ABSTRACT:
A pacemaker system and method are provided with an improved way of detecting the presence of noise, and particularly intermittent noise. When a first signal is sensed by the pacemaker sense circuit, the pacemaker schedules and starts to time out a next escape interval while continuing to time out the escape interval which was previously set. The pacemaker sets up a predetermined noise interval and continues to monitor senses, for the purpose of determining whether the first sense is to be treated as a true cardiac signal, or as noise. In the preferred embodiment, if a second sense occurs within the noise interval, and before time out of a minimum pacing interval, the first sense is determined to be noise, and the pacemaker continues to time out the initial escape interval; however, if no additional sense occurs during the noise interval, the pacemaker proceeds to time out the previously set next escape interval. In the case of a second sense within the noise interval but after time out of the minimum pacing interval, the second sense triggers a safety pace, to protect from continuous inhibition by pulsed noise.
