Ventricular standstill is a critical cardiac condition characterized by the complete cessation of electrical activity in the ventricles, which are the lower chambers of the heart responsible for pumping blood to the body. This leads to a sudden and severe drop in cardiac output, as the ventricles are unable to contract and pump blood effectively. It is a medical emergency that requires immediate intervention, as it can rapidly lead to a life-threatening situation. The causes of ventricular standstill can be varied, including severe electrolyte imbalances, certain medications, and conditions that affect the heart's electrical conduction system, such as complete heart block or third-degree atrioventricular (AV) block. In some cases, it can also occur due to a failure of the heart's pacemaker cells. Treatment for ventricular standstill typically involves the immediate use of a temporary pacemaker to restore the heart's rhythm. This is often followed by a thorough investigation to determine the underlying cause and to implement a long-term treatment plan. read more >>

Ventricular standstill is an uncommon yet potentially fatal arrhythmia, which requires urgent recognition and treatment. As the name suggests, the ventricles come to a standstill with an almost immediate cessation of cardiac output.read more >>
