Method and system for cardiac health monitoring

A system for monitoring a cardiac health of a subject by measuring an indicator of the cardiac health of a subject, the system comprising:

• a wearable device configured for being detachably attached to a thoracic region of the subject, the subject being ambulatory or at rest
• the wearable device comprising
• one or more sensors including one or more electrostatic sensors for sensing at least an electrocardiogram signal of the subject;
• and
• a communication module for communicating sensor data from the one or more sensors to a communication device;
• the communication device configured for
• receiving the sensor data from the wearable device,
• communicating the sensor data with a network server using a first communication channel and a second communication channel;
• and
• the network server being configured for
• receiving the sensor data from the communication device through the first communication channel and the second communication channel;
• processing the sensor data received from the first communication channel in real-time or near-real-time for performing one or more actions;
• comparing the sensor data received through the first communication channel and the second communication channel;
• storing the resulting sensor data;
• and
• processing the resultant sensor data for extracting information on the cardiac activity of the subject over a defined period of time.
