1. A method for use in monitoring a patient, the method comprising:
receiving, from a wearable cardioverter defibrillator (WCD) system, WCD system data, wherein the WCD system includes an electrocardiogram (ECG) electrode and the WCD system data comprises data generated based, at least in part, on an ECG signal of the patient that was sensed by the ECG electrode for at least one hour;
computing raw heart rate (HR) values for respective ones of short ECG signal segments of the ECG signal;
aggregating groups of the raw HR values into respective first time bins;
deriving first HR values for respective ones of the first time bins, from at least some of the raw HR values aggregated into each first time bin;
marking as error-prone a certain one of the first HR values for which an error condition is determined to be met;
storing the first HR values, the stored first HR values having been thus derived from the WCD system data;
displaying in a first manner the stored first HR values but not the certain one of the first HR values, and displaying in a second manner different from the first manner the certain one of the first HR values.
