Defibrillator Delivers A Shock To Patient

Defibrillator: Its Different Forms and Uses

A defibrillator is one very essential medical device. When a patient experiences ventricular fibrillation or ventricular tachycardia and thus dangerously fast and chaotic heartbeat, defibrillation is done to restore a normal heart rhythm. Also, patients with arrhythmogenic right ventricular dysplasia, cardiomyopathy, QT syndromes and survivors of sudden cardiac death need defibrillation. Using defibrillators help prevent cases of cardiac arrest and cardiac death.

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.

Defibrillators have several forms and sizes. Manual defibrillators or defibrillator paddles are what you see in a clinical setting such as the hospital. They can only be used by trained and skilled healthcare professionals. Automatic external defibrillators or AED can be used by lay people with only less training, which makes it perfect for emergency instances where no healthcare professional is present. ICDs or implantable cardioverter defibrillators are implanted in the patient’s chest.

Manual defibrillators can either be external or internal. External types work with electrocardiogram readers, which allow the clinician to diagnose a cardiac condition. Then, basing on previous knowledge and experience, the clinician will deliver the appropriate charge in joules through pads or paddles on the patient’s chest. Doing so requires detailed medical knowledge, and for this reason, these units are usually found only in hospitals and some ambulances.

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.

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.

ICDs or implantable cardio-verter defibrillators are another form. Such units are implantable (patient’s chest), and can perform the same function as pacemaking. ICDs regularly check on the patient’s heart rhythm, and if required, also corrects arrhythmia or abnormal heart rhythm based on the device’s programming. The pacemaker can be used together with ICDs for events that involve treating complex arrhythmias.

A defibrillator can come in various forms and uses. However, no matter how different they are in shape and size, they all aim to restore an unhealthy cardiac rhythm into a more normal rhythm. So, whether it’s automatic or manual, internal or external, or used only by medical professionals or lay men, it plays a significant role in saving lives of people.
