Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1] [2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.
Arrhythmias are due to problems with the electrical conduction system of the heart. [2] A number of tests can help with diagnosis, including an electrocardiogram (ECG) and Holter monitor. [5] Many arrhythmias can be effectively treated. [2] Treatments may include medications, medical procedures such as inserting a pacemaker, and surgery. [6]
If a life-threatening arrhythmia is detected, the device can deliver a small electric shock to terminate the abnormal rhythm and restart the heart. [ 1 ] Implantable defibrillators are often recommended for those with CPVT who have experienced blackouts, ventricular arrhythmias or cardiac arrest despite taking appropriate medication. [ 2 ]
Some of these conditions can be minor, while others can be life-threatening. Coronary Artery Disease. Coronary artery disease is the most common type of heart disease. ... Arrhythmia. An ...
An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
Electrophysiologists are often involved when severe or life-threatening arrhythmias are being treated, or when multiple drugs must be used to treat an arrhythmia. Antiarrhythmic agents such as flecainide , dofetilide , and amiodarone are commonly used to try to control rhythms.
Life-threatening arrhythmias cause most sudden cardiac arrests, according to Cleveland Clinic. Even a low impact projectile or a strike to the middle of the chest with a hand ...
Ventricular fibrillation (vfib) – Fibrillation of the ventricles is a life-threatening arrhythmia and should be treated by defibrillation and is a medical emergency. Vfib results from uncoordinated contraction of the ventricles and defibrillation acts as a 'reset' to synchronize contraction (i.e., a normal rhythm).
