Heart pacing and intracardiac electrogram monitoring system and associated method
First Claim
1. An implantable human heart pacing and monitoring system comprising:
- (a) an implantable housing;
(b) a heart pacer circuit within said housing;
(c) a first pacing-sensing electrode connected to said pacer circuit;
(d) a telemetry circuit within said housing;
(e) an A-V data lead connected to said telemetry circuit and including a data wire electrically separate from said first pacing-sensing electrode and;
(I) a detecting atrium ring electrode, and(II) a detecting ventricle ring electrode, wherin said atrium ring and said ventricular ring are electrically tied in common to said data wire, and said data wire is operable to feed a complete intracardiac electrogram to said telementry circuit; and
(f) a coil connected to said telemetry circuit and operable to transmit at least one pacer circuit function and the complete paced and nonpaced intracardiac electrogram.

Abstract
A heart pacing and monitoring system includes a new lead system which, when used in conjunction with a telemetry-pacemaker system, permits the transmission of the complete intracardiac electrogram and is not adversely affected by pacemaker outputs or after potentials. Detecting ring electrodes are placed in both right atrium and ventricle in order to optimize electrogram (EGM) detection. Electrically separate from the pacing-sensing electrodes, the detecting electrodes are structurally part of a transvenously placed ventricular lead no larger than a conventional bipolar lead. The EGM telemetry system is also compatible with telephone monitoring systems. The present system is operative to detect and telemetrically record the entire normal and abnormal electrogram even in pacer dependent patients.

8. A method for pacing and monitoring a human heart, the steps comprising:
-
(a) implanting an implantable heart pacing and monitoring system within a patient, said system including an implantable housing, a heart pacer circuit within said housing, a first pacing-sensing electrode connected to said pacer circuit, a telemetry circuit within said housing, an A-V data lead including a data wire electrically separate from said first pacing-sensing electrode and; (I) a detecting atrium ring electrode, and (II) a detecting ventricle ring electrode, said atrium ring and said ventricular ring being electrically tied in common to said data wire; and a coil connected to said telemetry circuit, said system being implanted with said atrium ring electrode in the patient'"'"'s atrium for P-wave detection, and said ventricle ring electrode in the patient'"'"'s ventricle for R-wave detection; (b) pacing the patient'"'"'s heart by operation of said first pacing-sensing electrode and said pacer circuit; (c) feeding a complete intracardiac electrogram from said ring electrodes to said telemetry circuit by said data wire; (d) transmitting said intracardiac electrogram across the patient'"'"'s skin by way of said coil; and (e) receiving said intracardiac electrogram by an externally located telemetry probe connected to heart monitoring equipment. - View Dependent Claims (9, 10, 11, 12, 13)
