The rhythm is regular, at a rate of 36 beats/min. The QRS complex duration is normal (0.08 sec), and there is normal morphology, although there is poor R wave progression from V1-V3, which is ...

The diagnosis is normal sinus rhythm, second-degree atrioventricular (AV) block-Mobitz type I or Wenckebach, and sinus node exit block (Figure 2). The rhythm is regular except for two long RR ...
