2:1 atrioventricular block is a form of second-degree AV nodal block and occurs when every other P wave is not conducted through the AV node to get to the ventricles, and thus every other P wave is ...
The atrial rate is approximately 160 beats per minute (bpm) with inverted P waves in II-III-AVF. The narrow ventricular complexes are regular at 80 bpm, with 2:1 atrioventricular (AV) block. These ...
All cases admitted or discharged from our institution between January 2008 and June 2009 with a diagnosis of AV block were reviewed. In addition, beginning in June 2009, data from all patients ...
This is a narrow complex tachycardia with a rate of 124 beats/min. The QRS morphology and axis are normal. The QTc is prolonged, at 529 ms (normal, 390-450 ms for men). The underlying P waves appear ...
Right ventricular pacing restores an adequate heart rate in patients with atrioventricular block, but high percentages of right ventricular apical pacing may promote left ventricular systolic ...
Patients with atrioventricular (AV) block who don’t have an indication for cardiac resynchronization therapy (CRT) do better when treated with conduction-system pacing versus right ventricular septal ...
