Clinical utility of aVR lead T-wave in electrocardiogram of patients with ST-elevation myocardial infarction.

ABSTRACT:

Background

aVR lead is often neglected in routine clinical practice largely because of its undefined clinical utility specifications. Nevertheless, positive T-wave in aVR lead has been reported to be associated with poor clinical outcomes in some cardiovascular diseases. This study aimed to prospectively investigate the prognostic value and clinical utility of T-wave amplitude in aVR lead in patients with acute ST-elevation myocardial infarction (STEMI).

Methods

A total of 340 STEMI patients admitted to a tertiary heart center were consecutively included. Patients were categorized into four strata, based on T wave amplitude in aVR lead in their admission ECG (i.e. < - 2, - 1 to - 2, - 1 to 0, and ≥ 0 mV). Patients' clinical outcomes were also recorded and statistically analy
