Abstract
A direct-implantable electrocardiographic (ECG) probe device includes a biocompatible housing, a battery disposed within the housing, one or more electrodes including an ECG electrode configured to sense an electrical signal in tissue of an atrium of a heart, circuitry disposed at least partially within the housing and configured to generate an ECG signal and wirelessly transmit the ECG signal through a chest wall, and an attachment structure configured to facilitate the attachment of the ECG probe device to a surface of the atrium.

A direct-implantable electrocardiographic (ECG) probe device comprising:
- a biocompatible housing;
- a battery disposed within the housing;
- one or more electrodes including an ECG electrode configured to sense an electrical signal in tissue of an atrium of a heart;
- circuitry disposed at least partially within the housing and configured to generate an ECG signal and wirelessly transmit the ECG signal through a chest wall;
- and
- an attachment structure configured to facilitate attachment of the ECG probe device to a surface of the atrium.
A heart monitoring system comprising:
- a plurality of electrocardiographic (ECG) leads configured to:
- be directly implanted in a surface of an atrium of a heart of a patient;
- sense an electrical signal in tissue of the atrium;
- and
- provide an ECG signal based on the sensed electrical signal;
- a monitor device coupled to the ECG leads and configured to receive the ECG signal;
- and
- a grounding pad electrically coupled to the monitor device.
A method of generating an electrocardiographic (ECG) signal, the method comprising:
- implanting one or more ECG probes on a surface of a heart of a patient;
- and
- generating an ECG signal using the implanted one or more ECG probe devices.
