Causes of malignant arrhythmias

Malignant arrhythmia is mostly secondary to various myocardial diseases, severe myocardial ischemia, etc.

If the patient has basic cardiomyopathy, such as hypertrophic cardiomyopathy, dilated cardiomyopathy, restrictive cardiomyopathy, etc., it can easily lead to abnormal heart structure and myocardial fibers in the patient. Scars appear, which can lead to malignant arrhythmia or sudden cardiac death. In addition, the acute phase of acute myocardial infarction can easily cause severe myocardial ischemia, and the heart is prone to ventricular tachycardia or fibrillation. Examination can reveal malignant arrhythmia, which can lead to sudden death.

It is recommended that patients even if they go to the hospital for treatment, they should actively receive treatment after identifying the cause.
