Wireless cardiac sensor

A wireless cardiac sensor is provided. The sensor may be utilized by a patient, on themselves, in an at home or other non-clinical environment. A sensor housing contains ECG electrodes and an audio transducer to simultaneously capture heart sound and ECG data with a single device. The ECG electrodes may be positioned on opposite sides of, and preferably adjacent to, an audio transducer sensor, for placement against a user's chest. The wireless cardiac sensor may include a button on a surface opposite the ECG electrodes and audio sensor, facilitating one-handed operation by a patient. The sensor transmits acquired data to a personal electronic device, such as a smartphone, via a wireless communication link. The personal electronic device may in turn transmit data to a centralized server and/or health care provider devices, via a wide area network.
