Claim 0:
1. A method of cardiac monitoring, comprising:
continuously sensing an activity level of a user with a first sensor of a wearable device comprising a wristlet or a smartwatch worn by the user;
continuously sensing a set of heart rate parameters of the user with a second sensor of the wearable device;
in response to sensing a resting activity level, comparing, using a machine learning (ML) algorithm, the resting activity level with the set of heart rate parameters to determine whether a discordance is present between the resting activity level and the set of heart rate parameters sensed when the resting activity level is sensed, wherein the set of heart rate parameters comprise an indication of a heart rate variability and an indication of a heart rate value;
in response to determining that the discordance is present:
indicating to the user, using the wearable device, a possibility of an arrhythmia being present;
initiating an ECG of the user using ECG electrodes of the smartwatch;
receiving electric signals of the user from the ECG electrodes of the smartwatch; and
displaying an ECG rhythm strip from the received electric signals; and

improving an accuracy with which the ML algorithm to identifies an arrhythmia by:
storing the resting activity level and the set of heart rate parameters as part of a historical set of parameter values, the historical set of parameter values including previously recorded resting activity levels and previously recorded heart rate parameters;
storing the ECG rhythm strip as part of a historical set of ECG data comprising previously recorded ECG rhythm strips; and
training the ML algorithm by comparing the historical set of parameter values with the historical set of ECG data.
