What causes antegrade atrioventricular reentrant tachycardia?

1. Drug stimulation

If the patient uses cyclophosphamide, adrenaline and other drugs for a long time, it may cause myocardial damage, resulting in abnormal cardiac conduction, which may induce orthodromic atrioventricular reentrant tachycardia.

2. Developmental malformation

Due to congenital abnormality, cardiac conduction is abnormal, which may cause orthodromic atrioventricular reentrant tachycardia.

3. Coronary atherosclerotic heart disease

If the patient has coronary atherosclerotic heart disease, atherosclerosis occurs in the coronary artery, resulting in myocardial ischemia and necrosis, affecting myocardial conduction, causing the above situation.
