Differential response to cardiac resynchronization therapy and clinical outcomes according to QRS morphology and QRS duration.
OBJECTIVES The goal of this study was to examine the relative impact of QRS morphology and duration in echocardiographic responses to cardiac resynchronization therapy (CRT) and clinical outcomes. BACKGROUND At least one-third of all patients treated with CRT fail to derive benefit. Patients without left bundle branch block (LBBB) or patients with smaller QRS duration (QRSd) respond less or n...
متن کاملInfluence of Intrinsic Myocardial Conduction on Paced QRS Morphology During Cardiac Resynchronization Therapy Follow up
We report two cases of patients of cardiac resynchronization therapy (CRT) whose ECGs, during follow up, showed different paced QRS morphology as compared to those of immediate post-device implantation. Parameters of leads, including sensitivity and capture thresholds, were unchanged. There was no lead dislodgement confirmed on fluoroscopy. The ECGs obtained in device off mode showed different ...
متن کاملDifferential Echocardiographic Response to Cardiac Resynchronization Therapy and Clinical Outcomes According to QRS Morphology and QRS Duration
Results A total of 496 patients were included in the study; 216 (43.5%) had LBBB and a QRSd 150 ms, 85 (17.1%) had LBBB and QRSd 150 ms, 92 (18.5%) had non-LBBB and a QRSd 150 ms, and 103 (20.8%) had nonLBBB and QRSd 150 ms. Echocardiographic response (change in ejection fraction) was better in patients with LBBB and QRSd 150 ms (12 12%) than in those with LBBB and QRSd 150 ms (8 10%), non-LBBB...

متن کاملOptimizing the pacing site in the ventricular septum by fluoroscopy and morphology of the paced QRS complex.
AIMS To analyze the paced QRS duration in various septal positions of the right ventricular leads and with different paced QRS vectors. To use the results to assess parameters suggesting the optimal site for right ventricular pacing. METHODS AND RESULTS A total of 609 patients with leads implanted in the right ventricular septum were classified using fluoroscopy in the lateral view (the prima...
