Hereditary diseases, which often manifest as ventricular tachycardia, can lead to cardiac arrest, cardiologist Marina Yakovleva. According to Doctor Peter, a sudden stop, according to the specialist, can even a perfectly healthy heart. "When as a result of an incredible set of circumstances - a sudden arrhythmia, a one-time spasm - a person dies and then, during the autopsy, it is impossible to understand what led to his death," said Yakovleva. If the patient had already had an acute myocardial infarction or has been diagnosed with an ischemic heart disease with heart failure, all this could lead to cardiac arrest. According to the specialist, there are also secondary causes that lead to cardiac arrest, for example, changes in the blood, as well as improper physical activity.
