Defibrillator: Its Different Forms and Uses

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.

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 are both internal and external manual defibrillators. The clinician diagnoses a cardiac condition through external units that work in conjunction with electrocardiogram readers. After the diagnosis, the clinician then decides on the charge in joules to deliver to the patient’s chest, and sends the shock through pads or paddles. Medical knowledge and experience is needed to perform this treatment, thus they are only generally found in hospitals and some ambulances.

Manual internal defibrillators are just about identical to the external version. The difference is that the charge is delivered through internal leads attached to the heart. The leads are used to detect when the heart is experiencing a rhythm that demands a shock, and to deliver the shock. Generally, you can find these units exclusively in operating rooms, where the chest is likely to be open, or can be quickly opened by a surgeon.

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 the different types and uses of a defibrillator. But although they are different in shape and size, all of them have a specific goal. That is to convert an unhealthy cardiac rhythm into a more normal rhythm. And whether, it is used by medical professionals or lay men, external or internal, automatic or manual, it helps lessen incidences of cardiac arrest or cardiac death.
