Long-term efficacy of physiologic dual-chamber pacing in the treatment of end-stage idiopathic dilated cardiomyopathy

Effect of Beta-Blocker Treatment in Dilated Cardiomyopathy With Bradyarrhythmias

“…Recently, some investigators have suggested that dualchamber pacing has a beneficial therapeutic effect for patients with severe DCM symptoms. [19][20][21] However, in our study the one patient who already had a permanent dualchamber pacemaker implanted did not show any beneficial effects with the pacing therapy or the additional betablocker therapy. Another patient who had permanent ventricular pacing did not improve by pacing therapy alone, but showed improvement after additional betablocker therapy.…”

Why Cardiac Resynchronization Therapy (CRT) is Usually Prescribed along with Automatic Implantable Defibrillation (AID)? Is it a Sensible Decision? Historical Perspective

“…Another significant reference is the DAVID Trial [9]. Several other papers appeared about dual-chamber pacing applied to congestive heart failure during the last decade of the former century; in fact and without expressly saying it, all aimed at correcting rightleft ventricular dyssynchrony, but mostly centering the criterion on the A-V delay [10][11][12][13][14][15][16][17][18][19]. Observe that the last reference comes from a multicenter clinical study, and it is over 17-years-old.…”

Interfacing with the nervous system: a review of current bioelectric technologies

“…For decades, implantable cardiac pacemakers and defibrillators have been in widespread clinical use and have proven efficacious in the long-term treatment of many cardiac disorders [1,50,71]. Recently, this technology has been adapted by Mueller et al to serve as a laryngeal pacemaker system implanted directly into laryngeal muscles in patients with bilateral vocal fold paralysis to improve breathing and swallowing, without compromising vocalization [94].…”
