Device and method for determining a criterion of frequent occurance or severe extrasystoles (atrial or ventricular)

摘要

The device includes device for detection of cardiac activity signals in at least a cardiac cavity and device for determining a cardiac cycle, device for sensing the occurrence of extrasystolic activity, an extra-systolic counter, device for incrementing the extrasystolic counter so as to sense each extra-systole, and device for decrementing, for each cardiac cycle, the extra-systolic counter in the absence of extra-systoles. The device also includes device for attributing a weighting to each extrasystolic detection. The incrementing device applies to the detection of each extrasystole the weighting associated with it. The application of a weighting is also applied by the decrementing device, in the absence of extrasystolic activity.
