Minimizing right ventricular pacing

The American Journal of Cardiology, 2005
e v w t c p M t w large body of evidence has emerged recently in several important trials (Dual Chamber and VVI mplantable Defibrillator, Multicenter Automatic Defirillator Implantation Trial-II [MADIT-II], Mode Selecion Trial, Danish AAIR vs DDDR, and Post AV Nodal blation Evaluation [PAVE]), thus underscoring the armful effects of long-term right ...

Pacing for Ventricular Tachycardia

Pacing and Clinical Electrophysiology, 1984
Plusieurs problèmes restent à résoudre avant que les stimulateurs puissent jouer un rôle majeur dans le traitement de la tachycardie ventriculaire. Nous citons des exemples pour illustrer quelques difficultés à résoudre. les mécanismes qui contribuent au succès ou à l'échec de la stimulation antitachycardie sont discutés.

Selective site ventricular pacing

Current Opinion in Cardiology, 2006
The 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 pacing in atypical ventricular tachycardia

Journal of Electrocardiology, 1981
Ventricular pacing was effective in controlling recurrent bouts of atypical ventricular tachycardia (Torsade de Pointes), in four patients. This arrhythmia was induced by quinidine or disopyramide therapy. Isoproterenol, which is the usually recommended therapy, was ineffective in two of the patients and was considered hazardous in two others.

Long-term left ventricular pacing

Acta Cardiologica, 2000
A 57-year-old female was implanted with a Biotronik Pikos VVI pulse generator. During her follow-up period right bundle-branch block was observed. Therefore further posteroanterior and lateral chest X-ray and echocardiography were performed. Only the transoesophageal echocardiography showed exactly the abnormal pathway of the electrode through the ...

Tachyarrhythmias Despite Ventricular Programmed Pacing

IEEE Transactions on Biomedical Engineering, 1970
Ventricular-programmed pacemakers are designed to avoid the possibility of dangerous or lethal arrhythmias provoked by stimulation during the vulnerable phase of the ventricle. Even so, rapid heart action (tachyarrhythmia) may still occur. Illustrative examples are presented in which tachyarrhythmia is presumed to have occurred or in which the ...

Selective site right ventricular pacing

Heart, 2009
The right ventricular apex (RVA) has been the elective site for placing endocardial pacing leads since 1959 when Furman described the use of the transvenous route for pacemaker implantation. This site was used because it is easily accessible, readily identified and associated with a stable position and reliable chronic pacing parameters.

Adaptive Pacing During Ventricular Fibrillation

Pacing and Clinical Electrophysiology, 2003
While it has been shown that pacing during ventricular fibrillation (VF) can capture a portion of the epicardium, little is known about the characteristics of the area captured or about whether adaptively changing the pacing rate during VF will increase the area captured.

Asystole Following Left Ventricular Pacing

Pacing and Clinical Electrophysiology, 2004
During biventricular ICD implantation, pacing the epicardial inferior posterior‐lateral surface of the left ventricle via the coronary sinus produced asystole. The proposed mechanism is a Bezold‐Jarisch reflex manifested by a drop in heart rate and blood pressure through direct C fiber stimulation. (PACE 2004; 27[Pt. I]:815–817)
