Abstract: Electrical activity from tissue of a patient is monitored using a plurality of external electrodes to generate a plurality of electrical signals over time. The plurality of electrical signals are filtered using a first filter having a first frequency range to generate a plurality of first filtered signals. The plurality of electrical signals are filtered using a second filter having a second frequency range different than the first frequency range to generate a plurality of second filtered signals. At least one QRS complex is detected based on the plurality of first filtered signals. A QRS peak of the at least one QRS complex is detected based on the plurality of second filtered signals and the detected at least one QRS complex.
