What is abnormal heart?

Cardiac ST segment abnormalities may be caused by arrhythmia, myocardial ischemia, myocarditis and other factors, and the correlation analysis is as follows:

1. Arrhythmia

arrhythmia will cause abnormal heartbeat rhythm, resulting in myocardial excitability changes, causing potential remodeling, resulting in ECG ST segment abnormalities.

2. Myocardial ischemia

Myocardial ischemia is a common cause of ST segment abnormalities. When coronary artery blood supply is insufficient or blocked, myocardial damage may lead to ST segment elevation or depression, usually accompanied by chest pain, dyspnea and nausea.

3. Myocarditis

Myocarditis can lead to myocardial injury and inflammatory reaction, resulting in myocardial function impairment, resulting in ST segment abnormalities. Other related symptoms may include fever, fatigue, etc.
