RMS Electrocardiography System and Method
First Claim
1. A system for assessing a cardiac condition of a subject, the system comprising:
- electronic circuitry configured to record a plurality N of electrocardiographic signals from the subject to generate an ECG (electrocardiogram), the plurality N of signals including at least one of a standard clinical ECG recorded with 12 leads, and a Holter data stream; and
a processor configured to compute an RMS (root-mean-square) magnitude function from the recorded signals, and to measure from the RMS magnitude function one or more RMS variables that contain information about the cardiac condition of the subject.

Abstract
A system for assessing a cardiac condition of a subject includes a sensor configured to record a plurality N of electrocardiographic signals from the subject to generate an ECG (electrocardiogram). The system further includes a processor configured to compute an RMS (root-mean-square) magnitude function from the recorded signals, and to measure from the RMS magnitude function an RMS variable that contains information about the cardiac condition of the subject. The ECG may be a standard 12-lead clinical ECG. The measured RMS variables may include RMS T-wave width, RMS RT recovery time, and RMS QT interval.
