| Popis: | Hemodynamic evidence of systolic assist after dynamic cardiomyoplasty remains inconsistent. One of the relevant factors may be how the burst stimulator is programmed. In 3 patients who underwent cardiomyoplasty for idiopathic dilated cardiomyopathy, we examined the modes used to determine the delay period between the R-wave sensing and the onset of burst stimulation during cardiac systole. These modes include the fixed time mode, the valve-synchronized mode, and the flow-optimized mode. The rationale for choosing these modes and the benefits conferred by each are discussed. |
