Abstract

Abstract An implantable apparatus for the detection and monitoring of spontaneous cardiac electrogram features in a comprises a cardiac monitoring device and a plurality of subcutaneous cardiac sensing electrodes electrically connected to the monitoring device. The sensing electrodes are configured for sensing cardiac electrogram features when implanted in spatially separate locations in a patient. A storage device contained within the monitoring device is operably associated with the subcutaneous electrodes and stores the cardiac electrogram features. Preferably, the plurality of subcutaneous electrodes are carried by a single elongate lead. A downloading device such as telemetry apparatus or transcutaneous electrical connectors may be provided so that the stored information can be downloaded to a separate apparatus external to the patient. In a preferred embodiment, the apparataus is a defibrillator. Methods of using such apparatus are also disclosed.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 110 words
A method for detecting cardiac electrogram features in a patient in need thereof, comprising: providing a plurality of subcutaneous sensing electrodes implanted in spatially separate locations in said patient, wherein said plurality of subcutaneous electrodes are carried by a single elongate lead; providing an implantable cardiac monitoring device operably associated with said subcutaneous sensing electrodes; detecting cardiac electrogram features through said plurality of sensing electrodes; and storing said detected cardiac electrogram features in said monitoring device to provide stored electrical activity; and extending said elongate lead from the xiphoid process of the sternum of said patient to a cardiac monitoring device implanted in the left pre-pectoral position in said patient.
Claim 2
Independent Claim 110 words
A method for detecting cardiac electrogram features in a patient in need thereof, comprising: providing a plurality of subcutaneous sensing electrodes implanted in spatially separate locations in said patient, wherein said plurality of subcutaneous electrodes are carried by a single elongate lead; providing an implantable cardiac monitoring device operably associated with said subcutaneous sensing electrodes; detecting cardiac electrogram features through said plurality of sensing electrodes; and storing said detected cardiac electrogram features in said monitoring device to provide stored electrical activity; and extending said elongate lead from the xiphoid process of the sternum of said patient to a cardiac monitoring device implanted in the left pre-pectoral position in said patient.
Claim 3
Dependent Claim 24 words
A method according to claim 1, further comprising the step of downloading said stored electrical activity to a separate apparatus external to said patient.
Claim 4
Dependent Claim 39 words
A method according to claim 2, further comprising the steps of: analyzing said stored electrical activity following said downloading step; and then generating a therapeutic recommendation for managing cardiac arrhythmia for said patient based on said stored electrical activity.
Claim 5
Dependent Claim 34 words
A method according to claim 1, further comprising positioning one of said subcutaneous electrodes adjacent the xiphoid process of the patient, and another of said subcutaneous electrodes adjacent the left axilla of the patient.
Claim 6
Dependent Claim 43 words
A method according to claim 1, wherein said detecting step comprises the step of detecting an event selected from the group consisting of QT interval, PR interval, ST interval, RT interval, T wave duration, QRS duration, R wave morphology, and T wave morphology.
