[Antitachycardia pacing efficacy significantly improves with cardiac resynchronization therapy].
INTRODUCTION AND OBJECTIVES The effect of cardiac resynchronization therapy on antitachycardia pacing still has to be determined. PATIENTS AND METHOD A total of 490 heart failure patients with an indication for an implantable cardioverter-defibrillator participated in the VENTAK CHF/CONTAK CD study, a single-blind, randomized, placebo-controlled study. We compared antitachycardia pacing effic...
متن کاملOptimizing Antitachycardia Pacing
Implantable cardioverter-defibrillators (ICDs) substantially reduce sudden cardiac death. Paradoxically, even though ICDs are implanted to prevent sudden cardiac death by delivering therapies, appropriate and inappropriate ICD shocks have been associated with an increased risk of mortality.1 However, patients treated with ICD shocks show even poorer survival than patients treated with antitachy...
متن کاملHeart failure during cardiac pacing.
BACKGROUND Right ventricular apical (RVA) pacing creates abnormal left ventricular contraction, hypertrophy, and reduced pump function. The adverse effects of ventricular desynchronization may explain the association of RVA pacing with an increased risk of heart failure hospitalization (HFH) in clinical trials. METHODS AND RESULTS Baseline and postimplantation variables were used to predict H...
متن کاملTagged cardiac MRI: detection of myocardial boundaries by texture analysis
The noninvasive evaluation of the cardiac function presents a great interest for the diagnosis of cardiovascular diseases. Cardiac tagged MRI allows the measurement of anatomical and functional myocardial parameters. This protocol generates a dark grid which is deformed with the myocardium. Tracking the grid allows the displacement estimation in the myocardium. The work described in this paper ...
