Heart stoppages are a medical emergency where the heart suddenly ceases to beat. The condition is also known as cardiac arrest, sudden cardiac arrest, or sudden cardiac death. Other synonyms for the same condition include heart failure, arrhythmia, cardiovascular collapse, and cessation of heartbeat. Sudden cardiac arrest can be caused by various factors, including heart disease, electrical abnormalities in the heart, trauma, and drug overdose. It is a serious and life-threatening condition that requires immediate medical attention. Symptoms of heart stoppages include sudden loss of consciousness, absence of breathing, and lack of pulse. In such cases, performing cardiopulmonary resuscitation (CPR) immediately can increase the chances of survival.
