defibrilasyon

Defibrilasyon, also known as defibrillation, is a medical procedure used to restore normal electrical activity of the heart in cases of sudden cardiac arrest caused by arrhythmias such as ventricular fibrillation or pulseless ventricular tachycardia. The procedure involves delivering a controlled electrical shock to the heart through electrodes placed on the chest, aiming to depolarize a critical mass of cardiac cells and allow the heart's natural pacemaker to re-establish a normal rhythm.

Defibrilasjon is a critical intervention in emergency situations and is often performed using an automated external defibrillator (AED) or a manual defibrillator by trained medical personnel. The success of defibrillation depends on factors such as the timing of the shock and the location of the electrodes. Early defibrillation significantly improves survival rates in cases of sudden cardiac arrest.

The procedure is generally considered safe when performed correctly, but it can cause side effects such as skin burns at the electrode sites or, rarely, heart arrhythmias. Proper training and adherence to guidelines recommended by health authorities are essential for effective and safe use.

Defibrilasjon is a key component of advanced cardiac life support (ACLS) protocols and is often combined with cardiopulmonary resuscitation (CPR) to maximize chances of patient recovery. With increasing accessibility of AEDs in public spaces, immediate defibrillation has become a vital tool in public health efforts to reduce mortality from sudden cardiac events.
