AEDs Are Implanted Just Under The Skin In Chest
Different Types and Uses of a Defibrillator
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.
For life-threatening cardiac arrhythmias ventricular fibrillation and pulseless ventricular tachycardia, defibrillation is the definitive treatment. In this treatment, a defibrillator is used to deliver a therapeutic dose of electrical energy to the affected heart. Before the affected heart suffers from sudden cardiac arrest, defibrillation works to restore normal heart rhythms. It depolarizes a critical mass of the heart muscle, ends the arrhythmia, and reestablishes normal sinus rhythm.

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.
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.
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.
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.
