A Pilot Study Comparing the Programmed Delay Between the Atrial and Ventricle Interval

Stopped early · Early Phase 1

Conditions studied: Heart Failure

In brief

The idea of this study is to compare different ways of setting up a pacemaker, using blood tests to give us information about how well it's working. We hope to learn if we can use this approach to figure out the best pacemaker setup ("programming") for each individual patient. The setting we propose to adjust is the timing between the impulse sent between top and bottom chambers.
