Infarcts and Ischemia ECG 11
- Normal sinus rhythm
- Ventricular paced rhythm
- Anterior myocardial infarction
Technically, the diagnosis of an anterior myocardial infarction on an ECG has never been validated in the setting of a paced rhythm. However, that was the case in this ECG; there was acute occlusion of the proximal left anterior descending coronary artery. Note that the ST segments in V4 and V5 are dramatically elevated in a shape different from a normal paced QRS morphology, which is in a left bundle branch block pattern. This meets Sgarbossa criteria; but again, this has not been validated in a paced rhythm.
