Abstract
In some embodiments, a cardiac monitoring system includes multiple sensors configured for implantation in a cardiovascular system of a user. Each sensor includes a sensing unit configured to be disposed in sensory communication with the location for measuring a biological parameter in the at least one heart chamber. The sensing unit is also configured to generate a sensory signal associated with the biological parameter. Each sensor also includes a wireless transceiver configured to receive the sensory signal from the sensing unit. The wireless transceiver is further configured to wirelessly transmit the sensory signal to an external processing device disposed outside a body of the user. The external processing device monitors, based on the sensory signal received from at least two sensors from the plurality of sensors, cardiac health associated with at least one of an implanted device or a surgery.
