Multi-vessel coronary artery disease (CAD) is associated with worse outcome in non-ST segment elevation myocardial infarction (NSTEMI) patients. Depending on the severity of CAD, there may be prolongation of atrial depolarization time as a result of left ventricular dysfunction and atrial ischemia. Therefore, we aimed to study whether the severity of CAD can be predicted with the P wave peak time (PWPT) in the electrocardiography (ECG) obtained during the diagnosis in NSTEMI patients. A total of 162 patients were included. The coronary angiography records of all patients were analyzed and SYNTAX scores were calculated. Patients were divided into two groups, according to CAD severity. In addition to well-known P wave parameters, PWPT, defined as the time from the beginning of the P wave to its peak, was measured in the leads DII and V1. The PWPTs in the leads DII and V1 were significantly longer in the group with severe CAD (71 ± 13 vs. 61 ± 12, p
