Selective site ventricular pacing
Current Opinion in Cardiology, 2006The traditional site for ventricular pacing, the right ventricular apex, produces an abnormal pattern of ventricular depolarization and there is growing evidence that pacing from this site is associated with adverse functional and structural changes in the left ventricle. This is manifest clinically as an increased morbidity and mortality.

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 ...

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 ...

The Prescription of Minimal Ventricular Pacing
Pacing and Clinical Electrophysiology, 2012Contemporary devices include sophisticated algorithms specifically designed to minimize ventricular pacing, with the intention of limiting the patient's exposure to potentially deleterious effects of right ventricular pacing. The added complexity and adverse effects (some potentially life‐threatening) associated with the use of these algorithms are ...

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.

An Esophageal and Gastric Approach to Ventricular Pacing
Pacing and Clinical Electrophysiology, 1995Using a unipolar esothoracic pacing system (where current passes from a point source positioned in the distal esophagus to a chest wall pad) and pulse duration of 50 msec, satisfactory 1:1 ventricular capture was obtained in57 (86%) of 66 patients, with a mean threshold current of 27.7 mA at an optimal depth of 40.3 cm from the lower lip.

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 ...

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

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 ...
