Wireless cardiac sensor

A wireless cardiac sensor comprising:

• a sensor housing having a first rectangular side for positioning against a user's chest, wherein the sensor housing is a rectangular cuboid in shape having first and second long rounded edges and first and second short rounded edges;
• a battery within the sensor housing for powering the sensor;
• an ECG transducer within the sensor housing, the ECG transducer comprising plurality of electrodes exposed on a first side of the sensor housing for recordation of ECG data measured from skin of a patient;
• an audio transducer within the sensor housing, the audio transducer comprising an audio transducer sensor exposed on the first side of the sensor housing for recordation of heart sound data, wherein the ECG transducer electrodes and the audio transducer sensor collectively form a sensor package on the first side of the sensor housing, wherein a first ECG transducer has a first curved and linear edge at the first short rounded edge and a second transducer has a first curved and linear edge positioned away from the second short rounded edge, and wherein the first curved and linear edges of the first and second transducer extend across the diameter of the audio transducer;
• and
• a wireless transceiver, the transceiver adapted for transmitting said ECG data recorded by the ECG transducer and said heart sound data recorded by the audio transducer, to a personal electronic device in near-real time;
• in which the sensor housing also has a second side opposite the first side, the sensor further comprising a button for actuation by a user, the button exposed on the second side of the sensor housing and positioned directly above the sensor package.

A wireless system, comprising:

• a sensor housing having a first side for positioning against a user's chest;
• a battery within the sensor housing for powering the sensor;
• an ECG transducer within the sensor housing, the ECG transducer comprising plurality of electrodes exposed on the first side of the sensor housing for recordation of ECG data measured from skin of a patient;
• an audio transducer within the sensor housing, the audio transducer comprising an audio transducer sensor exposed on the first side of the sensor housing for recordation of heart sound data,
• wherein the ECG transducer comprises two electrodes positioned on opposite sides of, and adjacent to, the audio transducer sensor, such that the ECG transducer electrodes and audio transducer sensor form a sensor package occupying only a portion of the first side of the sensor housing, wherein the audio transducer sensor is circular and wherein the two electrodes each have an edge extending across a diameter of the transducer, the edge adjacent the circular audio transducer and each have linear edges defining opposite edges from the adjacent edges;
• a wireless transceiver, the transceiver adapted for transmitting said ECG data recorded by the ECG transducer and said heart sound data recorded by the audio transducer, to a personal electronic device proximate the sensor;
• and
• the personal electronic device proximate the sensor (“PED”), the PED comprising:
• a PED wireless transceiver configured for communication with the sensor wireless transceiver to convey cardiac data therebetween;
• and
• a user interface comprising a graphical display screen configure to render displays conveying diagnostic information derived from cardiac data received by the PED wireless transceiver, wherein the user interface is configured to visually prompt the user regarding positioning of the housing.
