Defibrillators Raise The Quality Of Life

Various Forms and Uses of a Defibrillator

A defibrillator plays a very important role in the field of medicine. It is used to restore a normal heart rhythm through sending an electrical shock to the heart when heartbeat becomes dangerously fast due to ventricular fibrillation or ventricular tachycardia. Both conditions may be life-threatening, and could lead to cardiac arrest, and even cardiac death. Other conditions that require defibrillation are long QT syndrome, cardiomyopathy, and arrhythmogenic right ventricular dysplasia and survivors of sudden cardiac death.

Defibrillation is the ultimate treatment for life-threatening cardiac arrhythmias ventricular fibrillation and pulseless ventricular tachycardia. To deliver a therapeutic jolt of electrical energy to the affected heart, a defibrillator is used. Such treatment restores normal heart rhythms before cardiac arrest occurs. It works by depolarizing a critical mass of the heart muscle, stopping the arrhythmia, and reestablishing normal sinus rhythm.

Patients with a history of myocardial infarction and a reduced ejection fraction are at increased risk for life-threatening ventricular arrhythmias. Which of these patients are the most appropriate candidates for implantable cardioverter-defibrillator (ICD) therapy is unclear. Factors influencing the decision are discussed.

There are different forms and sizes of defibrillators. Those types you see in a hospital are called manual defibrillators or defibrillator paddles or, and they can only be operated by healthcare professionals. On the other hand, the AED can be used by lay people with only less training, which is handy for emergency purposes where no healthcare professional is around. ICDs or implantable cardio-verter defibrillators are implantable in the patient’s chest.

There’re two types of manual defibrillators: external and internal. External units work together with electrocardiogram readers. Through the device, the clinician can diagnose a cardiac condition, decide on the right amount of charge in joules, and send the shock through pads or paddles. However, such process necessitates thorough medical knowledge and experience. Because of that, you can only see these units in hospitals and some ambulances, generally.

Manual internal defibrillators are similar to manual external defibrillators. Only, internal leads which are in direct contact to the heart are used to deliver the shocks. The leads function both ways: either to detect an abnormal rhythm or to deliver the actual shock. Usually, you can find such units in operating rooms, where the chest is likely to be open, or can be easily opened by a surgeon.

When there is any cardiac arrest, a device called defibrillator is used to give electrical energy to the heart to release it from the arrest. With the advancement in the technology automatic defibrillator leads are developed and fitted ...

For emergency cases where no healthcare professional is around, AEDs are available. Automated external defibrillators are based on computer technology to study the heart rhythm and advise whether a shock is necessary. Unlike manual types, AEDs can be used by lay persons with less training. PADs or public access defibrillators are AEDs that can be found in public places including airports, hotels, and shopping centers. There are also some AEDs which are held by trained personnel who will attend incidents.

Implantable cardio-verter defibrillators or ICDs are another type. They are implanted in the patient’s chest, and could function similarly to pacemaking. ICDs continuously observe and monitor the patient’s heart rhythm, and if necessary, also correct an irregular heart rhythm (arrhythmia) depending on the device’s programming. A pacemaker can also be used in conjunction with an ICD to treat complex arrhythmias.

Those are some of the various forms and uses of a defibrillator. Although they vary in shapes and sizes, all of them aim to convert an unhealthy cardiac rhythm into a more standard rhythm. It plays a significant role in saving lives of people, whether the unit is automated or manual, internal or external, or used by medical professionals or lay men.
