What is the meaning of ST segment changes in sporadic atrial extrasystoles?

ST-segment change of occasional atrial extrasystoles refers to the occasional occurrence of atrial ectopic beats earlier than the basal rhythm, accompanied by ST-segment changes.

When ECG examination, if it indicates ST-segment change of occasional atrial extrasystoles, it means that ECG occasionally finds atrial ectopic beats earlier than the basal rhythm, and there are ST-segment changes. Such phenomena are mostly considered to be caused by myocardial ischemia, which can be caused by vasospasm angina pectoris, myocardial bridge, coronary atherosclerotic heart disease, etc. Systematic examination should be carried out in time to clarify the cause.
