What arrhythmia is commonly seen during cardiac arrest?

Ventricular tachycardia is a common arrhythmia encountered during cardiac arrest, particularly in cases of sudden cardiac arrest due to underlying heart conditions. This fast, abnormal heart rhythm originates in the ventricles and can lead to ineffective contractions, preventing the heart from pumping blood effectively to the body.

In the context of cardiac arrest, ventricular tachycardia can often degenerate into ventricular fibrillation, a chaotic and unsustainable rhythm that results in the cessation of effective blood circulation. The presence of ventricular tachycardia indicates a critical state of the heart's electrical system and signals the need for immediate intervention, such as CPR and defibrillation. Understanding the nature of the arrhythmias that occur during cardiac arrest is crucial for healthcare providers as they guide the appropriate and timely response to restore normal heart function.
