Smartwatch assemblies having electrocardiogram sensors, photoplethysmography sensors, and blood pressure monitors and related methods

A smartwatch assembly, comprising:

• an outer frame portion;
• an insert portion removably insertable into the outer frame portion, the insert portion comprising:
• a casing;
• a controller disposed within the casing;
• an electrocardiogram sensor operably coupled to the controller, the electrocardiogram sensor having at least two electrodes configured to be placed in contact with a user's skin;
• a photoplethysmography sensor operably coupled to the controller and oriented to face the user's skin;
• and
• a display operably coupled to the controller and configured to show data related to measurements taken by the electrocardiogram sensor and the photoplethysmography sensor,
• wherein the photoplethysmography sensor is configured to detect trigger events in a heart function of the user,
• wherein, in response to the detection of a trigger event, the smartwatch assembly is configured to alert the user of the detected trigger event via the display, and
• wherein, in response to a user interaction, the electrocardiogram sensor is configured to initiate an electrocardiogram measurement.

A smartwatch assembly system, comprising:

• at least one processor;
• and
• at least one non-transitory computer-readable storage medium storing instructions thereon that, when executed by the at least one processor, cause the system to:
• monitor a user's heart function via a photoplethysmography sensor;
• detect a trigger event related to the user's heart function via the photoplethysmography sensor;
• in response to detecting the trigger event, initiate an electrocardiogram measurement of the user via an electrocardiogram sensor;
• and
• show data related to the electrocardiogram measurement via a display.
