Circulation: Arrhythmia And Electrophysiology On The Beat

Dr Paul Wang:                   Welcome to the monthly podcast On The Beat, where Circulation: Arrhythmia and Electrophysiology. I'm Doctor Paul Wang, editor in chief, with some of the key highlights from this month's issue.                                                 In our first paper, Parikshit Sharma and associates reported on the use of permanent his bundle pacing to improve hemodynamics in 39 patients with right bundle branch block. His bundle pacing was successfully performed in 37, or 95 percent of the patients, and resulted in narrowing of the QRS complex from 158 milliseconds to 127 milliseconds. P = 0.0001. An increase in left ventricular ejection fraction from 31 percent to 39 percent. P = 0.004, an improvement in the New York Heart Association functional class from 2.8 to 2.0 P = 0.0001. This work suggests that his bundle pacing maybe helpful in right bundle branch block patients with left ventricular dysfunction.                                                 In our next paper, Philippe D
