Defibrillator: Its Different Forms and Uses

In the field of medicine, a defibrillator plays a very essential role. When heartbeat becomes dangerously fast and chaotic due to ventricular fibrillation or ventricular tachycardia, defibrillators deliver an electrical shock to the heart to restore a normal heart rhythm. Using it helps prevent cardiac arrest and cardiac death from happening. Patients with cardiomyopathy, arrhythmogenic right ventricular dysplasia, QT syndrome or survivors of sudden cardiac death require defibrillation.

Defibrillation is the best treatment for life-threatening cardiac arrhythmias ventricular fibrillation and pulseless ventricular tachycardia. It works by sending a therapeutic jolt of electrical energy to the affected heart through a device called a defibrillator. This treatment depolarizes a critical mass of the heart muscle, stops the arrhythmia, and reestablishes normal sinus rhythm. It restores normal heart rhythms before the affected heart suffers from sudden cardiac arrest.

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.

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.

For emergency purposes, automated external defibrillators are available. These units rely on computer technology to analyze the heart rhythm and advise whether a shock is needed. AEDs can be used by lay persons, who call for little training. Generally, they are held by qualified personnel who will attend incidents or are PADs or public access defibrillators that can be found in airports, hotels, shopping centers, and corporate or government offices, among others.

Then, there’re implantable cardioverter defibrillators or ICDs. These units are implanted in the patient’s chest, and they may also perform the pacemaking function. ICDs constantly monitor the patient’s heart rhythm, and if needed, also correct an abnormal heart rhythm or arrhythmia according to the device’s programming. In the event of complex arrhythmias, such devices can be combined with a pacemaker.

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.
