Abstract: A system for monitoring a heart of a patient, the system includes: (i) a physiological data input interface, operative for receiving signals indicative of cardiac activity of the patient; (ii) a processor configured to process the signals to provide monitoring results; and (iii) an output interface operative to provide the monitoring results; wherein the monitoring results include information indicative of: (a) a heart rate of the patient during a monitoring period; (b) at least one first time period in which the heart rate of the patient exceeded a first threshold; and (c) at least one second time period in which the heart rate of the patient exceeded both the first threshold and a second threshold.
