Key result
Peak endocardial acceleration dynamic monitoring produced physiological pacing rates that were highly correlated with metabolic needs during exercise (r = 0.97).

Does peak endocardial acceleration (PEA) sensor-driven rate responsive pacing provide physiological pacing rates related to metabolic needs in patients with AVB/SSS?
Effect estimate: r = 0.97
The PEA sensor in the SORIN Best Living System produces physiological pacing rates that correlate highly with metabolic needs during exercise.
Greco et al. (2003) conducted an observational in Advanced AVB and/or SSS (n=15). Peak endocardial acceleration (PEA) sensor vs. Predicted metabolic pacing rate profiles was evaluated on Correlation between deltaPEA exercise steps and calculated energy cost of exercise (MET) (r = 0.97). Peak endocardial acceleration dynamic monitoring produced physiological pacing rates that were highly correlated with metabolic needs during exercise (r = 0.97).
