Dynamic atrioventricular delay programming improves ventricular electrical synchronization as evaluated by 3D vectorcardiography

Atrioventricular Synchronization

Complete heart block implies an absolute independence between atria and ventricles that does not in fact always exist. Segers showed that, after complete block was artificially produced in the frog's heart, atria and ventricles would sometimes begin to beat exactly in phase, most commonly in a 2 to 1 ratio. He subsequently reported one clinical example of 2 to 1 A-V synchronization in a patient...

Optimization of Programming in Dynamic Cardiomyoplasty: Enhancing Synchronization of Muscle Wrap and Ventricular Contractions

Introduction: To obtain maximal benefit from dynamic cardiomyoplasty, stimulation parameters of the cardiomyostimulator need to be optimized. The two components for optimization include the muscle channel and the synchronization channel. This study looks at the issue of timing muscle contraction to ventricular contraction. Specifically, we compared 2 methods of obtaining optimal synchronization...
