Quantitation of basal dyssynchrony and acute resynchronization from left or biventricular pacing by novel echo-contrast variability imaging.

OBJECTIVES This study sought to test a novel echocardiographic method based on contrast variability imaging (CVI), to quantify cardiac dyssynchrony and magnitude of resynchronization achieved by left ventricular (LV) and biventricular (BiV) pacing therapy. BACKGROUND Left ventricular or BiV pacing is a promising new therapy for patients with heart failure and intraventricular conduction delay...

A comparison of cardiac resynchronization by sequential biventricular pacing and left ventricular pacing to simultaneous biventricular pacing: rationale and design of the DECREASE-HF clinical trial.

BACKGROUND The first generation of cardiac resynchronization therapy (CRT) devices approved for the treatment of heart failure used simultaneous biventricular (BiV) pacing to achieve ventricular resynchronization. Left ventricular pacing alone and sequential BiV pacing also show promise as alternative ways to deliver CRT, but have not been studied together in a large randomized trial. METHODS...

lectrocardiographic imaging of cardiac resynchronization herapy in heart failure: Observation of variable lectrophysiologic responses

BACKGROUND Cardiac resynchronization therapy (CRT) for congestive heart failure patients with delayed left ventricular (LV) conduction is clinically beneficial in approximately 70% of patients. Unresolved issues include patient selection, lead placement, and efficacy of LV pacing alone. Being an electrical approach, detailed electrical information during CRT is critical to resolving these issue...

Dual intraventricular response after cardiac resynchronization

Figure 1 A: Baseline electrocardiogram (ECG) during biventricular pacing at 60 beats per minute showing an underlying left atrial flutter and bigeminy. The premature ventricular complexes have the same morphology and a coupling interval of 630 ms, indicated by the blue rectangle. B: Baseline ECG, after reprograming the lower pacing rate at 30 beats per minute, showing poor residual atrioventric...

Effect of epicardial or biventricular pacing to prolong QT interval and increase transmural dispersion of repolarization.

Prolong QT Interval and Increase Transmural Dispersion of Repolarization To the Editor: The recent article by Medina-Ravell et al1 addresses a potentially harmful effect of cardiac resynchronization therapy on ventricular repolarization. The authors found that single epicardial and biventricular pacing in patients with congestive heart failure increased the QT interval and the transmural disper...
