AEDs Are Implanted Just Under The Skin In Chest
Various Forms and Uses of a DefibrillatorA 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 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 patients 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 patients 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.
Similar to the external version are manual internal defibrillators. However, for these units, the charge is sent by internal leads in direct contact to the heart. When the heart is experiencing an abnormal rhythm, the leads detect it and deliver the required electrical shock. Typically, you can see these units in operating theatres where the chest is likely to be open.

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 ...
Automated external defibrillators are available for emergency purposes. They are preprogrammed units using computer technology that are designed to analyze the heart rhythm and advise whether a shock is required. Lay persons can operate AEDs with minimal training. They are either PADs or public access defibrillators and can be found in corporate or government offices, hotels, airports and shopping centers. Or, they could be held by skilled personnel who will attend incidents.
ICDs or implantable cardio-verter defibrillators are another form. Such units are implantable (patients chest), and can perform the same function as pacemaking. ICDs regularly check on the patients heart rhythm, and if required, also corrects arrhythmia or abnormal heart rhythm based on the devices programming. The pacemaker can be used together with ICDs for events that involve treating 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.
