Filter by:The purpose of this study is to evaluate the exercise capacity of patients with complete heart block who are chronically being paced from the right ventricle. Also, we hope to correlate the level of uncoordinated contraction with the patients exercise capacity. We will enroll patients with complete heart block as diagnosed by standard electrocardiographic means and now have a permanent pacemaker. All patients we approach for this study will receive an echocardiogram to assess their heart function. As part of the echocardiogram, they will also receive a Tissue Synchronization Imaging (TSI) evaluation to assess the level of uncoordinated contraction they have. The patients will then be subjected to a cardiac exercise stress test which will involve them running on a treadmill until they cannot continue while data is collected regarding their heart's response to exercise. All portions of the study are noninvasive, which means they work from probes and monitors outside the body.
Pacemakers are implantable devices that pace (electrically stimulate) the heart. Some pacemakers have special programs to treat irregular atrial rhythms(top chambers of the heart beat too fast or too slow). Advances in pacemaker technology in recent years include features that automatically adapt to patient conditions without intervention from the clinician. Adapta (Model #ADDR01) is a new pacemaker that is designed to provide further automaticity advances by including the managed ventricular pacing (MVP) feature designed to promote intrinsic conduction (natural flow of electricity in the heart) by reducing unnecessary ventricular (lower chamber of the heart) pacing (electrical impulses). Adapta also contains a feature called TherapyGuide that is designed to allow the user to select certain conditions for each subject and receive a list of suggested pacemaker parameter value changes based on those conditions. The purpose of this study is to evaluate the overall system safety and clinical performance of the Adapta pacing system.
The purpose of this study is to collect data from pacemakers and determine how this information is used by physicians to care for their patients with pacemakers.
