• 1 other identifier: E17154
• Study Type: interventional
• Target: 5
• Locations: 1 country
• Sites: 2

Brief Summary

This study will address whether acute adaptive RV pacing in sinus rhythm patients with severe LV systolic dysfunction and RBBB is superior to no ventricular pacing, and is as effective as echocardiographically optimized biventricular (BIV) pacing based on Medtronic ECG belt and cardiac performance as assessed by the echocardiographic parameters of RV and LV function.

Conditions

Right Bundle-Branch Block

Outcome Measures

Primary Outcomes (1)

• Effectiveness of adaptive Right Ventricular (RV) pacing

  Echocardiographic parameters to measure cardiac function, including: 1. Left Ventricular Outflow Tract velocity time interval(LVOT VTI), 2. dP/dt of Left Ventricle (LV) and RV, 3. Myocardial Performance Index (MPI), 4. Right Ventricular Outflow Tractvelocity time interval (RVOT VTI); and 5. 3D derived Systolic Dyssynchrony Index (SDI).

Secondary Outcomes (1)

• Battery/device longevity

CRT Optimization

OTHER

Each patient will have atrial pacing 10% higher than the sinus rate or atrial pacing at a rate of 60 bpm if significant sinus bradycardia is present. Each patient will have six ECGs and echocardiographic sequences performed in the same session. In addition six electrical activation evaluations by the Medtronic ECG belt will be done as well. The first study will always be with no ventricular pacing. One study will be echocardiography-optimized BIV pacing and four studies for echocardiography-optimized (?) adaptive RV-only pacing with different AV intervals. A random-sequence will be performed to determine the order for the rest of the studies.
