Abstract:
An active implantable medical device, comprising:means for detecting spontaneous events in a ventricular or atrial cardiac cavity; means for measuring an interval separating successive detected events; means for analyzing a heartbeat rate, according to said measured intervals; and means for eliminating double detection of a detected event comprising means for evaluating successive measured intervals (t1, t2, t3, t4, t5, t6, . . . ) separating a series of consecutive detected events (R1, Râ€²1, R2, Râ€²2, R3, Râ€²3, . . . ), and identifying therefrom a short interval and a long interval and an alternation of short intervals (t1, t3, t5, . . . ) and long intervals (t2, t4, t6, . . . ) in said successive intervals as a double detection corresponding to a detected spontaneous event followed by a detected artifact.
