Dome and dart P wave is seen in: A. Left atrial rhythm B. Right atrial rhythm C. Sinus rhythm D. Junctional rhythm Answer: A The dome and dart P wave in left atrial rhythm is seen in Lead V1. The initial dome represents the left atrial activation and the terminal dart represents the right atrial [...]

Which of the following rhythms is taken as a marker of successful ablation of atrioventricular nodal re-entrant tachycardia (AVNRT)? A. Ventricular tachycardia B. Sinus rhythm C. Junctional rhythm D. Atrial fibrillation Answer: C Usually a short run of accelerated junctional rhythm occurs during successful radiofrequency catheter ablation of AVNRT. Non inducibility of tachycardia is an [...]

Click on the image for a larger view This tracing shows a normal ECG with sinus rhythm at about 75 per min. Sinus rhythm is identified as a narrow QRS rhythm with P waves preceding each QRS complexe with a fixed and normal PR interval in the range of 120 to 200 msec. P waves [...]

Click on the image for an enlarged view Regular sinus rhythm at about 60 per minute with a wide QRS is noted. The PR interval is 200 msec. The initial Q waves in II, III and aVf suggests an old inferior wall myocardial infarction. The QRS is wide, lasting 160 msec. The slurred S waves [...]
