Right Atrial Pacing Impairs Cardiac Function During Resynchronization Therapy
OBJECTIVES We aimed to compare the hemodynamic effects of right-atrial-paced (DDD) and right-atrialsensed (VDD) biventricular paced rhythm on cardiac resynchronization therapy (CRT). BACKGROUND Cardiac resynchronization therapy improves hemodynamics in patients with severe heart failure and left ventricular (LV) dyssynchrony. However, the impact of active right atrial pacing on resynchronizatio...

متن کاملCardiac Resynchronization Therapy; Biventricular Pacing
Although the estimates from limited studies vary on the proportion of patients with heart failure who also have ventricular dyssynchrony as reflected by a prolonged QRS complex, often in the form of left bundle branch block, the number of such patients is large (27% to 53%) and it is certainly in excess of the rate for the general population. Among these patients, 10% to 15% are candidates for ...
متن کاملRight atrial appendage pacing in cardiac resynchronization therapy – haemodynamic consequences of interatrial conduction delay
The present case report describes a patient with an artificial mitral valve and dual chamber pacemaker implanted due to perioperative complete atrio-ventricular block. One year later an upgrade to cardiac resynchronization therapy (CRT) combined with ICD function was performed due to significant progression of heart failure symptoms. Beneficial effects of CRT are demonstrated, but unfavourable ...
متن کامل[Cardiac pacing and cardiac resynchronization therapy].
In this issue of iJACC (JACC: Cardiovascular Imaging), Botvinick et al. (1) perform a complex study involving the performance of equilibrium radionuclide myocardiography with phase analysis during ventricular tachycardia. The authors identify specific characteristics that define tolerability of the arrhythmia in individual patients. Most of these discriminating factors in the 2 patient groups i...
