Frequent atrial premature triple beats in patients with coronary artery disease are not myocardial ischemia, but a type of arrhythmia. Atrial premature beats are atrial anisotropic beats that occur before the normal heartbeat; triple rhythm is two normal heartbeats plus one atrial premature beat; and frequent refers to the number of occurrences of more than five per minute; and premature beats refer to the rhythm of the heartbeat has changed, so atrial premature beats in triple rhythm belongs to a kind of arrhythmia; frequent atrial premature beats in triple rhythm can induce myocardial ischemia. And myocardial ischemia is a pathological state, is due to coronary artery stenosis and caused by the myocardial blood supply and oxygen supply is insufficient; the typical clinical manifestations of the patient is the anterior region of the heart pain, discomfort, serious cases can have anterior region of the heart pain, pressure sensation; and myocardial ischemia can be accompanied by cardiac arrhythmia. Arrhythmia and myocardial ischemia is not a concept, so frequent atrial tricyclic rhythm is not myocardial ischemia, if you have symptoms of physical discomfort, you should go to the hospital in time to consult a physician’s guidance.
