Abstract: An electrocardiography (ECG) monitoring device may be configured to receive ECG data from a patient via one or more sensors. The ECG monitoring device may transition between different types of ECG monitoring in response to a trigger condition being satisfied. Types of ECG monitoring may differ by various aspects, such as one or more of: an update interval for transmitting ECG data over an electronic network via a communication component; whether analysis of the ECG data is performed onboard the hybrid ECG device; characteristics or events to be detected via the onboard analysis; a sensitivity level for the onboard analysis; whether detection of a characteristic or event results in generation of a notification or an alert; or information included in a notification or alert.
