Atrial pacemaker

An artificial atrial pacemaker stimulates the atria to generate a rhythm. The most common type is AAI, where the atria are sensed to detect if there is an adequate intrinsic rhythm and pacing is only delivered if required. This causes a pacemaker spike before the p wave.

Can you see through this paced rhythm? 30424

This ECG is from an elderly woman who presented with 2 hours of chest pain on a background of multiple stents, a pacemaker, stroke and COPD.

This ECG shows paced rhythm with excessively discordant ST segments (modified Sgarbossa positive). The cause was a 95% thrombotic lesion of the RCA.

A 50-something with h/o coronary bypass has chest pain and a ventricular paced rhythm – 5, post cath 16409

This ECG is from a man in his 50s who presented with chest pain on a background of previous CABG and dual chamber pacemaker. This was the second repeat ECG after intervention.

This ECG shows dual chamber paced rhythm with some native beats.

A 50-something with h/o coronary bypass has chest pain and a ventricular paced rhythm – 4, post intervention 16406

This ECG is from a man in his 50s who presented with chest pain on a background of previous CABG and dual chamber pacemaker. This was the repeat ECG post intervention.

This ECG shows atrial pacing with resolved ST elevation but T wave inversion in inferior leads and upright T wave in aVL. The cause was an inferior and right ventricular MI.
