Leonard Bernstein's Young People's Concerts with the New York Philharmonic stand among his greatest achievements. These televised programs introduced an entire generation to the joys of classical music. Bernstein conducted his first Young People's Concert on January 18, 1958, just two weeks after becoming Music Director of the New York Philharmonic. Such programs were already a Philharmonic tradition when Bernstein arrived, but he made them a centerpiece of his work, part of what he described as his "educational mission." Looking back on the concerts years later, he referred to them as being "among my favorite, most highly prized activities of my life." When he took a sabbatical season from the orchestra in 1964-65, he still came back to lead the Young People's Concerts. He continued to lead these programs until 1972, even though he had stepped down as director of the Philharmonic in 1969. Bernstein led a total of fifty-three Young People's Concerts during those fourteen years, and covered a broad range of subjects. The works of the great composers were explored, including tributes to modern masters such as Dmitri Shostakovich, Paul Hindemith, Gustav Holst, Aaron Copland and Charles Ives. Bernstein discussed "Jazz in the Concert Hall," "Folk Music in the Concert Hall," and "The Latin-American Spirit." He explained the intricacies of Music Theory in programs such as "Musical Atoms: A Study of Intervals" and "What is a Mode?" He broached complex aesthetic issues such as "What Does Music Mean?" (his first program) with clarity and without condescension. Bernstein also used the Young People's Concerts to introduce young performers to the musical world. The sixteen year-old pianist André Watts made his debut in the concert of January 15, 1963. Originally broadcast on Saturday mornings, the programs were considered so important that for three glorious years CBS presented them at 7:30 p.m. (prime time for television viewing). Eventually the programs were moved to Sunday afternoons. The concerts were translated into other languages and syndicated to forty countries.

Doctor Says You Need a Pacemaker? The Three Biggest Mistakes to Avoid

!±8± Doctor Says You Need a Pacemaker? The Three Biggest Mistakes to Avoid

If you just suddenly got the news that you might need a pacemaker, you are going to find out two things. First, it's a big decision. Second, no one is really out there trying to help you make that decision. Your doctor may advise you to take a few days to "think about" getting a pacemaker. But what exactly should you think about? You're going to find out there is not a whole lot of information available to the general public. The information that exists is mainly geared to doctors. So how do you make a decision.

There are three big mistakes you can make when considering a pacemaker.

The first mistake occurs when people try to make the decision without doing any research or getting any facts. Granted, there may be situations where you could need to get a pacemaker or defibrillator immediately; but these would be pretty rare. In most cases, you should have the freedom to take a few days or weeks to think about it without compromising your condition.

That being said, how exactly do you do research? You can go online and look at pacemaker-related sites but many times this information can be more confusing than helpful. A great resource are the pacemaker forums online. Just Google pacemaker + forum (or any keyword + forum) and you will turn up the current most active forums discussing this topic. While you may not get the most scientific information from forums, you will be able to "talk" online with real people who have pacemakers and were once in the position you're in now.

The second mistake most people make is that they do not ask specific questions of their doctor. Now this is understandable, because if your doctor just suddenly tells you that you might need a pacemaker, you probably don't know what to ask! If you have serious unanswered questions, make another appointment to see your doctor. Consider your physician as a consultant and adviser and get your questions answered.

When I say "specific," I mean that you should control the conversation. Most of us let the doctors do the talking, but doctors can be busy individuals who are not as sensitive as they could be to your particular concerns. You must know the real, medical name of what is wrong with your heart. Ask the doctor to spell it (or hand him or her a notepad and ask that it be written down). Do not let yourself be intimidated. Just because you're unfamiliar with these names today does not mean you can't learn about them.

You need to know the device the doctor is recommending. Is it a pacemaker or defibrillator? Now this question is a bit tricky in that every defibrillator contains a built-in pacemaker (but not the other way around). The point is, you need to know if your device is going to be the kind that might shock you (defibrillator) or not shock you (pacemaker). There is a third kind of device called a CRT system. If your doctor tells you that you need CRT, ask the same question again: is this a pacemaker or defibrillator? (CRT pacemakers don't shock, but CRT defibrillators do.)

That's it. Two questions. But using these questions, you can do research on your cardiac condition and the device the doctor recommends. There are far too many people walking around with pacemakers who never got those questions answered--and who may not even know them now!

If you have other concerns of your own, add those to the list and be sure and get a good, clear answer from your doctor. You may want to know when and where the pacemaker surgery is done, how long it will take, the risks of surgery, and so on.

The third mistake you can make when considering a pacemaker is not finding out who is doing the actual pacemaker implantation. Pacemakers are implanted in the upper chest in a procedure known as "minimally invasive surgery." However, all surgery has risks attached to it.

Ideally, your pacemaker should be implanted by a physician who does a lot of these implants with good success. So how can you find out? Ask! Your physician may be the one doing the implantation. Ask how many of these surgeries he has done a year and what kind of success he has had. If he does less than 10 implants a year, he is probably not as experienced at this kind of procedure as you would like.

Many doctors will refer you to another doctor for the actual implant. Find out how many such implants the physician doing your operation has performed. More is better. You can even call the hospital where your surgery is likely to be performed and ask how many pacemaker people are treated there every year.

Why is more better? The more frequently a doctor performs a surgery, the more skilled he or she becomes at the nuances of that particular operation. The more pacemaker patients a hospital treats, the better prepared they are at dealing with pacemaker-related concerns. If you are not happy with the physician your doctor recommends, you can tell the doctor that you would like the surgery to be performed by somebody who does this sort of operation very often.

Pacemaker implantation is considered "routine surgery," but it is not necessarily a common operation. Some hospitals probably do very few (or even no) pacemaker implantations at all. Those are the places you do not want to have your operation, even if it's a world-class hospital right next door to you. Find an experienced pacemaker implant team-or you can also ask your physician to find one for you.

If you hit a brick wall in this area, contact the Heart Rhythm Society at hrsonline.com to learn more about doctors who specialize in this type of work.

That's it. It is important for you to know the exact, medical name of your heart condition and exact name of the type of pacemaker or defibrillator you are being asked to consider. Use that information to do some research on your own: look things up online and while you're there, check out the forums to talk to other pacemaker people. Last but not least, make sure your implant team is experienced in pacemaker or defibrillator implant surgery.

Should you get a pacemaker? I'm not a doctor so I cannot tell you. Every medical procedure, even the simplest, has risks and benefits. It's a big decision, but it's one you can make with the help of your doctor and with a little bit of research!

Biphasic Defibrillators

!±8± Biphasic Defibrillators

A defibrillator is an instrument that carries out defibrillation on the chambers of the heart. When the device is implanted in the user, it is known as an implantable cardioverter or internal cardiac defibrillator (ICD). Traditionally, monophasic waveforms were used in these implements but research studies have shown that biphasic waveforms are better suited for such equipments.

In monophasic defibrillators, electrical pulses are sent rapidly from one electrode to the other, in a single direction. In case of biphasic defibrillation, the direction of the pulses alternates, completing one cycle in approximately 10 milliseconds. Biphasic defibrillation was originally developed and used for implantable cardioverter-defibrillators. They use a different waveform technology than the monophasic ones. It uses either a biphasic truncated exponential (BTE) waveform or a rectilinear biphasic waveform. In the first phase, the current moves from one paddle to the other as with monophasic defibrillators. During the second phase, the current flow reverses direction, thus lowering the electrical threshold for successful defibrillation.

The American Health Association has a different opinion about low-energy biphasic defibrillation. As per them, biphasic defibrillation is now a part of advanced cardiac life support guidelines. Biphasic shocks at energy levels of 200 joules or less are at least as safe and effective as monophasic shocks with traditional energies between 200 and 360 joules. Biphasic shocks of 200 joules or less are now classified as a Class II-A recommendation.

The biphasic defibrillation process varies depending on the specific biphasic waveform used. External biphasic defibrillation offers equal or better value at lower energies than traditional monophasic waveform defibrillators .It has less risk of post -shock myocardial dysfunction and skin burns. There is a significant cost and size saving which helps in the proliferation of the automated external defibrillators.

When low-energy biphasic shocks were used, the left ventricular ejection fraction and mean arterial pressure returned to baseline more quickly.
In conclusion, based on all the research studies carried out till date, biphasic cardioversion is more effective than monophasic cardioversion in patients with acute atrial fibrillation

Automated External Defibrillators

!±8± Automated External Defibrillators

In an industrial environment where there is a risk of electrical shocks or any other type of accident, having first aid measures in place to treat victims is essential in order to improve survival rates and provide on the spot aid as quickly as possible. An automated external defibrillator is a critical link in this first aid response and surviving a life threatening accident.

The first minutes after an accident are the most important time in treating the victims, and by having a fully trained first aid tech on site and them, the chances of the accident victim surviving and not suffering long term damage is greatly increased.

In the case of electrocution, the main threat to the person involved is that the shock can lead to a heart attack. The flow of high levels of electricity through the body disrupts the normal electrical patterns that control the heart's rhythm. This causes the heart to lose its natural rhythm and go into a state of cardiac arrhythmia, which can lead to a full cardiac arrest.

The most effective treatment against cardiac arrhythmia after an accident is the use of an Automated External Defibrillator or AED. These devices are similar to the defibrillators that are used in hospitals to treat patients who have suffered cardiac problems, but work in a slightly different way, and are designed to provide immediate on the spot care for victims of accidents.

Probably the most important aspect of the AED is the fact that it can be used by a person without extensive medical schooling, meaning that provided appropriate training has been given to the individual, an automatic external defibrillator can be used in the workplace.

The secret of the ease of use and simplicity from a treatment point of view of the AED is that it is automated. This contains a computer that is able to derive information from the patient's condition, analyse the information it collects, and then diagnose the exact problem. They can deliver a controlled and appropriate electric shock to the patient in order to cancel out the arrhythmia and allow the heart to return to its regular rhythm.

An automated external defibrillator offers a number of features that makes it simple to use and ideally suited to dealing with accidents. Firstly, the device can be used by almost anyone, as most of the functions and diagnosis work is carried out by the computer rather than by the operator, meaning that it will not be affected by the situation. In addition to this, they will provide feedback to the operator. All will determine initially whether any treatment is required, and only shock the patient if its programming advises it that it will be beneficial.

Most of them include a voice and recorder that collects information throughout the period of their usage. This data, which includes the heart condition of the patient as well as the sounds from the environment around the patient can be downloaded and subsequently analysed to make sure that everything possible was done, and that the device worked correctly. The data can also be used to ensure that future generations of them take into account more information to provide better diagnoses and treatment options to give better and ever more advanced treatment to victims.

Because an AED will only shock under circumstances under which it determines that the shock will correct the arrhythmia of a patient, users are protected under good faith legislation in the USA, which means that even if a patient dies as a result of the treatment being applied, the person who controlled and applied the automated external defibrillator cannot be held liable.

The reason why this particular protection is required is that under a high pressure situation, when seconds matter in delivering treatment to save the life of an accident victim, the rescuer should not be put off from doing their best for fear of a negative outcome.

The reason why every workplace should have at least one AED and trained operators is simple. By having an automatic external defibrillator available in the event of an accident that results in heart problems, the chances of the victim surviving are much higher than otherwise. Early treatment is vital in maximising the likelihood of a cardiac patient making a full recovery, and by having the equipment on hand in case of problems, your workplace will be a much safer place for everyone there.
