Described herein are systems, devices, and methods for cardiac monitoring. In particular, the systems, devices, and methods described herein may be used to conveniently sense the presence of an intermittent arrhythmia in an individual. The systems, devices, and methods described herein may be further configured to sense an electrocardiogram
Claim CLM-00001. 1. A method of cardiac monitoring, comprising:
sensing an activity level of a user with a first sensor on a wristlet or a smartwatch worn by the user; when the activity level is resting, sensing a heart rate parameter of the user with a second sensor on the smartwatch or wristlet; determining a discordance is present between the activity level value and the heart rate parameter; based on the presence of the discordance, indicating to the user, using the smartwatch or wristlet, a possibility of an arrhythmia being present; and receiving electric signals of the user from an electrocardiogram sensor (“ECG”) on the smartwatch or wristlet to confirm a presence of the arrhythmia, wherein the ECG sensor comprises a first electrode and a second electrode.

Claim CLM-00010. 10. A smartwatch or wristlet, comprising:
a processor, a first sensor configured to sense an activity level value of a user, wherein the first sensor is coupled to the processor, a photopletysmogram (“PPG”) sensor configured to sense a heart rate parameter of the user when the activity level value is resting, wherein the PPG sensor is coupled to the processor; an electrocardiogram (“ECG”) sensor configured to sense electrical signals of a heart, wherein the ECG sensor comprises a first electrode and a second electrode, and wherein the ECG sensor is coupled to the processor; and a non-transitory computer readable storage medium encoded with a computer program including instructions executable by the processor to cause the processor to:
determine if a discordance is present between the activity level value of the user and the heart rate parameter of the user;based on the presence of the discordance, indicate to the user a possibility of an arrhythmia being present;receive electric signals of the user from the ECG sensor to confirm the presence of the arrhythmia.
