Abstract
An electrocardiogram (ECG) monitoring system configured to determine an index that comprises a set of indicators, where each indicator is indicative of a level of signal quality in an ECG lead. Further, the ECG monitoring system assigns a first indicator from the set of indicators to a first ECG lead signal and communicates the first indicator to a user.
Claims20
An electrocardiogram (ECG) monitoring system configured to:
- determine noise from a first ECG lead signal, wherein the determination of the noise comprises subtracting a signal template corresponding to a noise-free cardiac signal from the first ECG lead signal;
- assign a signal quality indicator from a set of possible signal quality indicators to the first ECG lead signal based on the determined noise;
- and
- communicate the assigned signal quality indicator to a user.
1 more element
An electrocardiogram (ECG) monitoring system configured to:
- determine noise from a first ECG lead signal in two or more frequency segments, where the determination of the noise from the first ECG lead signal in at least one frequency segment comprises subtracting a noise-free signal template corresponding to a cardiac signal from the first ECG lead signal in the at least one frequency segment;
- assign a first indicator from a set of possible signal quality indicators to the first ECG lead signal, wherein the assignment of the first indicator is based on the determined noise from all frequency segments;
- and
- communicate the first indicator to a user.
