摘要:
An implantable heart monitoring device including a sensing unit, a signal quality analysis unit, and an evaluation unit. The sensing unit is connected to at least one electrode that picks up electric potentials. The sensing unit processes electrical signals corresponding to the electric potentials, and generates sense signals including events corresponding to myocardial contractions. The signal quality analysis unit determines whether a noise condition (NC) and/or a low signal indication is present for an event and generates an indication signal. The evaluation unit evaluates the sense signals and the indication signals, treats a detected event as non-valid if a NC and/or low signal indication signal is present for that event, and uses only intervals defined by two consecutive events which do not have a NC and/or a low signal indication to determine a rate of events of the sense signal.
