ST elevation in a PVC

ST elevation in a premature ventricular complex can provide very useful clues to differentiate between benign and ischemic ST elevation. For example, if the PVC has a RBBB shape, it suggests infarction if there is any concordant ST elevation present.

Another Cardiac Arrest – Is it OMI this time? Use your skills from the previous post! Repeat 23min later.

This ECG is from a male in his 40s who developed sudden shortness of breath and arrested soon after. This was the initial ECG after 5 shocks for VT/VF when he was intubated and without any spontaneous movements.

This ECG shows high lateral ST elevation. Within the PVCs there is excessive discordant ST elevation in I and aVL, as well as excessive depression in II, III, aVF, V5 and V6. The cause was an acute posterolateral MI. The ST segments were initially misinterpreted as being part of the QRS complexes.

A 70-something woman with syncope and a wide complex

This ECG is from a woman in her 70s who presented after a syncopal episode on a background of coronary artery disease.

This ECG shows wide complex rhythm with excessive discordant ST elevation in V1, V2 and aVR. The cause was a 90% proximal right coronary artery occlusion.
