Leadless wireless ECG measurement system for measuring of bio-potential electrical activity of the heart
First Claim
1. A leadless ECG measurement system for measuring of bio-potential electrical activity of the heart in a patient'"'"'s body, comprising:
- at least one multi-contact bio-potential electrode assembly adapted for attachment to the patient'"'"'s body, said electrode assembly being formed of an electronic patch layer and a disposable electrode layer;
said disposable electrode layer having a plurality of contact points for engagement with the surface of the patient'"'"'s body and configured to measure short-lead ECG signals in response to electrical activity in the heart; and
a processing unit being provided and configured to produce a transfer function which computes estimated long-lead ECG signals based on the measured short-lead ECG signals from said plurality of contact points, said processing unit employing a system identification technique to define said transfer function.
