The initial negative deflections in the QRSs of inferior leads suggest Q waves of inferior infarct. However, the PR interval is short and typical delta waves are present in other leads, proving that ...

Background: Baseline Q waves may provide additional value compared with time from the onset of symptoms in predicting outcomes for patients with ST-segment elevation. We evaluated whether baseline Q ...

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. There is an ...
