Peak endocardial acceleration-based clinical testing of the "BEST" DDDR pacemaker. European PEA Clinical Investigation Group.


The peak endocardial acceleration (PEA, unit g) shows a near correlation with myocardial contractility during the isometric systolic contraction of the heart (dP/dtmax), with sympathetic activity and, thus, with physiological heart rate modulation. The (Biomechanical Endocardial Sorin Transducer (BEST) sensor is incorporated in the tip of a pacing lead and… (More)
