What are the common causes of cardiogenic syncope?

Cardiac syncope more common causes are arrhythmia, cardiac output obstruction, myocardial disease itself, etc.

1, arrhythmia

whether chronic arrhythmia or tachyarrhythmia may lead to sudden decrease in cardiac blood transfusion volume, cerebral insufficiency and syncope.

2, cardiac output obstruction

If the patient has aortic valve stenosis, arterial dissection, etc., may lead to left ventricular blood flow obstruction, insufficient blood supply can lead to cerebral ischemia, and then syncope.

3, myocardial disease itself

If the patient has myocarditis, myocardial ischemia and other myocardial disease, cardiac contractility decreased, cardiac output decreased, can lead to cerebral insufficiency and syncope.
