A 76-year-old woman presents with a persistently rapid heart rate that she attributes to her pacemaker. What does the ECG show?

She returns for a follow-up visit for palpitations, and a 12-lead ECG is obtained ... in leads I and aVF and positive in leads aVR and V1 (^). A second atrial waveform is superimposed at the ...

The ECG also displayed a QR pattern with convex ST-segment elevation (STE) in leads V1, V2, and aVR, along with reciprocal ST-segment depression in the inferior and anterior (V1 to V4) leads. In ...

All the above results are obtained using single lead ECG for localization and detection. This helps in the reduction in device cost and improvement of patient comfort. These are the best results ...
