Right-Ventricular Pacing Catheterization
JAMA: The Journal of the American Medical Association, 1972To the Editor.— In answer to a question concerning the method of inserting a right-ventricular pacing catheter in a patient with acute myocardial infarction and complete heart block ( 219 :766, 1972), Dr. Samet responded by minimizing the usefulness of the "combined central venous pressure monitoring-pacing electrode catheter." I feel that the ...

Ventricular Fibrillation and Competitive Pacing
New England Journal of Medicine, 1967SUDDEN death in persons with artificial pacemakers is a continuing and disturbing problem. Causes include pacemaker-catheter displacement, electric-component failure, broken wires and rising pacing threshold. Each of these may be resolved in a relatively simple fashion once recognized.1 , 2 More of an unsolved problem is that of competitive rhythm ...

The American Journal of Cardiology, 1986
To assess the hemodynamic effects of physiologic pacing, 13 patients with DDD pacemakers who had varying degrees of atrioventricular (AV) block were studied with radionuclide ventriculography during VVI, DVI and VDD modes. Radionuclide ventriculography was performed with patient in the supine position at rest 5 to 10 minutes after the pacing mode and ...

Right ventricular enlargement mimicking electrocardiographic left ventricular pacing
Journal of Electrocardiology, 2006Electrocardiographic right bundle branch block morphology during cardiac pacing is occasionally the result of accidental placement of pacemaker or defibrillator leads into the left ventricle. Inadvertent lead placement in the left heart is associated with a risk of systemic embolism.

Right Ventricular Outflow Tract Pacing
Pacing and Clinical Electrophysiology, 1997“He who expresses an opinion should not voice it as correct and right but set it forth as a contribution to the consensus of opinion, for the light of reality becomes apparent when two opinions coincide. A spark is produced when flint and steel come together. Man should weigh his opinions with the utmost serenity, calmness, and composure.

Chronic right ventricular apical pacing (RVAP) has been associated with negative hemodynamic and clinical effects. The aim of the present study was to compare RVAP with right ventricular septal pacing (RVSP) in terms of echocardiographic features and clinical outcomes. A total of 93 patients without structural heart disease and with an indication for a

Is Right Ventricular Outflow Tract Pacing an Alternative to Left Ventricular/Biventricular Pacing?
Pacing and Clinical Electrophysiology, 2004The right ventricular apex has been used as the traditional pacing site since the development of transvenous pacing in 1959. Some studies suggest that pacing the right ventricular apex may cause remodeling and is harmful. In the past decade, there have been a multitude of studies of the hemodynamic, electrophysiological, electrocardiographic, and ...

Triple‐Site Ventricular Pacing in a Biventricular Pacing System
Pacing and Clinical Electrophysiology, 2001VAN GELDER, B.M., et al.: Triple‐Site Ventricular Pacing in a Biventricular Pacing System. This case report describes a patient with heart failure in whom a biventricular pacing system was successfully implanted. During control of the pacing system, three morphologies of the paced QRS complex could be elucidated.

Ventricular safety pacing, ventricular sense response, and ventricular tachycardia
Heart Rhythm, 2010The ventricular sense response (VSR) algorithm enforces biventricular pacing on ventricular sensing to maximize biventricular pacing in patients with atrial fibrillation. This report describes a case of recurrent ventricular tachycardia that may be facilitated by this enforced pacing algorithm.
