Journal ArticleDOI
Biventricular Pacing Decreases Sympathetic Activity Compared With Right Ventricular Pacing in Patients With Depressed Ejection Fraction
Mohamed H. Hamdan,Mohamed H. Hamdan,Jason Zagrodzky,Jose A. Joglar,Clifford J Sheehan,Karthik Ramaswamy,Jeffrey F. Erdner,Richard L. Page,Michael L. Smith +8 more
TL;DR: LV-based pacing results in improved hemodynamics and a decrease in SNA compared with RV pacing in patients with LV dysfunction regardless of the QRS duration.
Journal ArticleDOI
Biventricular pacing decreases the inducibility of ventricular tachycardia in patients with ischemic cardiomyopathy
Jason Zagrodzky,Karthik Ramaswamy,Richard L. Page,Jose A. Joglar,Clifford J Sheehan,Michael L. Smith,Mohamed H. Hamdan +6 more
TL;DR: The purpose of this study was to assess the effect of BV pacing on the inducibility of sustained monomorphic ventricular tachycardia in patients with coronary artery disease.
Journal ArticleDOI
Baroreflex Gain Predicts Blood Pressure Recovery During Simulated Ventricular Tachycardia in Humans
Mohamed H. Hamdan,Jose A. Joglar,Richard L. Page,Jason Zagrodzky,Clifford J Sheehan,Stephen L. Wasmund,Michael L. Smith +6 more
TL;DR: These data strongly suggest that arterial baroreflex gain contributes significantly to hemodynamic stability during simulated VT, and may help the clinician tailor therapy directed toward sustained VT.
Journal ArticleDOI
Effect of P-Wave Timing During Supraventricular Tachycardia on the Hemodynamic and Sympathetic Neural Response
Mohamed H. Hamdan,Mohamed H. Hamdan,Jason Zagrodzky,Richard L. Page,Stephen L. Wasmund,Clifford J Sheehan,Mathew M. Adamson,Jose A. Joglar,Michael L. Smith +8 more
TL;DR: The data suggest that the superior maintenance of hemodynamic stability during long-RP tachycardia is accompanied by reduced sympathoexcitation, which is primarily mediated by the arterial baroreceptors, with a modest cardiopulmonary vasodepressor effect.
Journal ArticleDOI
Increased sympathetic activity after atrioventricular junction ablation in patients with chronic atrial fibrillation.
Mohamed H. Hamdan,Richard L. Page,Clifford J Sheehan,Jason Zagrodzky,Stephen L. Wasmund,Karthik Ramaswamy,Jose A. Joglar,Michael L. Smith +7 more
TL;DR: The increase in SNA, along with the prolongation in APD, may play a role in the pathogenesis of ventricular arrhythmias that occur after AVJ ablation.
