Abstract: A method for QRS classification, the method may include generating, by a computer and based upon information representative of multiple QRS complexes of a patient, a QRS complex cluster tree; and updating, by the computer, the QRS complex cluster tree based upon information relating to other QRS complexes of the patient.

Abstract: A method for monitoring a heart of a patient, the includes receiving signals indicative of cardiac activity of the patient during a monitoring period; and processing the signals and providing monitoring results in response to a result of the processing; wherein the monitoring results comprise information indicative of: (a) the heart rate of the patient during the monitoring period; (b) at least one first time period in which the heart rate of the patient exceeds a first threshold; and (c) at least one second time period in which the heart rate of the patient exceeds both the first threshold and a second threshold.
