Question

The immediate cause of many deaths is ventricular fibrillation, an uncoordinated quivering of the heart, as opposed to proper beating. An electric shock to the chest can cause momentary paralysis of the heart muscle, after which the heart will sometimes start organized beating again. A defibrillator is a device that applies a strong elec-

Key Concepts

Defibrillation

Defibrillation is the process of delivering a controlled electric shock to the heart with the aim of resetting its electrical state. This intervention is used to convert a disorganized, life-threatening rhythm such as ventricular fibrillation into a stable, organized rhythm.

Cardiac Electrical Activity

Cardiac electrical activity involves the generation and propagation of electrical impulses that regulate the heartbeat. Disruptions in this finely tuned system, such as those seen in arrhythmias, can lead to serious conditions that may require interventions like defibrillation.

Ventricular Fibrillation

Ventricular fibrillation is a severe type of cardiac arrhythmia characterized by chaotic electrical activity in the ventricles, leading to uncoordinated contractions. This results in ineffective blood circulation and can quickly lead to cardiac arrest if not promptly treated.
