Figure 2.

Enlargement of initial electrocardiogram. This patient had pacemaker-mediated tachycardia near the upper rate limit of 120/min. A pacing stimulus (asterisk) precedes each ventricular complex, and a retrograde P wave (↓P) is seen just after each wide ventricular complex. The P wave axis (upright in aVR and inverted in II) indicates retrograde conduction.
