A Battery‐ and Leadless Heart‐Worn Pacemaker Strategy
Advanced Functional Materials, 2020Over the past half‐century, cardiac pacing technology has adhered to one basic system. However, many pacemaker‐related complications are related to this system, particularly in terms of the power supply and leads.

A Case of Pacemaker and Pacemaker-Like Syndrome
Journal of Interventional Cardiac Electrophysiology, 2003This report describes the occurrence of both pacemaker syndrome and a pacemaker-like syndrome (so-called "pseudopacemaker syndrome") in a patient who exhibited an atrioventricular junctional rhythm probably on the basis of sick sinus syndrome. The clinical and hemodynamic manifestations of the two clinical situations were similar and associated with ...

Pacemaker pseudodysfunction with a coronary sinus pacemaker
American Heart Journal, 1974Abstract A permanent transvenous coronary sinus pacemaker functioned effectively for 22 months both as an atrial and ventricular pacemaker. Slow atrial flutter resulted in failure of the pacemaker to capture the myocardium and thus incorrectly suggested pacemaker dysfunction.

Rapid advances in pacing technology will continue to affect the quality of life of many patients with cardiovascular disease. A truly "smart" device that seemed fanciful 30 years ago now seems to be a virtual certainty by early in the next century.

A brief overview of the history and development of circuit designs applied in pacemakers has been presented. The advances in IC designs have resulted in increasingly sophisticated pacing circuitry, providing, for instance, diagnostic analysis, adaptive rate response, and programmability.

Cardiac Electrophysiology Clinics, 2016
The electrocardiogram (ECG) raises the question of inappropriate device behavior and the possibility of ventricular lead oversensing causing failure of ventricular pacing. Careful analysis of the ECG proved that the mode of pacing was set to managed ventricular pacing (MVP) mode.

The pacemaker syndrome is a complex of clinical signs and symptoms related to the adverse hemodynamic and electrophysiologic consequences of ventricular pacing in the absence of other causes. Neurologic symptoms or those suggesting low cardiac output or congestive heart failure, temporally related to the onset of ventricular pacing, are indicative of ...

The American Journal of Medicine, 1970
Described here are seven cases of permanent transvenous pacemakers associated with a pacemaker click. The graphic findings and roentgenographic appearance of the catheter position are discussed. Although these cases appear to represent penetration at least of the right ventricular myocardium by the catheter tip, there was no evidence of pacemaker ...

The field of cardiac pacing has expanded rapidly in recent years. Engineering improvements and microprocessor technology have resulted in a vast increase in pacemaker technology. The "high-tech" edge of cardiac pacing often discourages all but the pacemaker specialist from approaching a malfunctioning pacemaker.
