METHOD FOR SAMPLING A CARDIAC PARAMETER, ESPECIALLY AN INTRACARDIAC IMPEDANCE, IN AN ACTIVE IMPLANTABLE MEDICAL DEVICE SUCH AS A STIMULATOR, CARDIAC, DEFIBRILATOR, CARDIOVERTER AND / OR MULTISITE DEVICE

摘要

P This method consists in repeatedly executing, during a plurality of successive cardiac cycles (CYCLE 1 .. CYCLE 8), the steps consisting in detecting the instant (E) of occurrence of a ventricular event, and operating then a sampling of said signal during the cardiac cycle with a constant sampling step and a predetermined time offset (DELTAT1 .. DELTAT8) between the detected ventricular event and the first sample, this time offset being a variable progressive offset of one cycle to the next. /P
