This is a classic example of atrioventricular nodal blocks that can occur with inferior ... ischemia and AV conduction abnormalities such as the second-degree type II AV block seen in the ECG.

There are Q waves in the inferior leads and in leads V1-V4 (anteroseptal leads). This indicates an infarction, possibly old. What is concerning about this ECG tracing are the ST segments.

VPDs with very short coupling intervals developing during an acute stage of myocardial infarction would predict the development of early cycled reentry, potentially culminating in VF, and requires ...
