What lethal arrhythmia can multiple PVCs in a row cause?

Multiple premature ventricular contractions (PVCs) occurring in rapid succession can lead to ventricular tachycardia (VT). This is a potentially life-threatening condition where the ventricles of the heart beat at an abnormally fast rate, disrupting normal blood flow and increasing the risk of more serious arrhythmias.

When multiple PVCs occur consecutively, they can result in a series of rapid beats that don't allow for sufficient filling of the ventricles, ultimately affecting cardiac output. If this rapid rhythm continues, it may progress to ventricular fibrillation, which is a more chaotic and lethal arrhythmia. However, the immediate concern of multiple PVCs is often the development of VT.

Atrial fibrillation, by contrast, originates in the atria and is characterized by rapid, irregular beating, making it unrelated to the effect of multiple contiguous PVCs. Asystole refers to a state of no electrical activity in the heart and is not directly caused by PVCs. Ventricular fibrillation involves chaotic electrical activity like ventricular tachycardia but is a different process and tends to follow it if not treated, rather than being an immediate consequence of multiple PVCs.

Thus, the progression from multiple PVCs leading directly to ventricular tachycardia
