Abstract
A TWA measuring apparatus includes: an electrocardiograph controlling section which is configured to produce an electrocardiogram from electrocardiographic signals of a subject; and a TWA measuring section which is configured to select at least two waveforms that contribute to a measurement of TWA, from the electrocardiogram, and which is configured to measure a presence of TWA by using the selected at least two waveforms.
Claims18
A T-Wave Alternans (TWA) measuring apparatus comprising:
- an electrocardiograph controlling section which is configured to produce an electrocardiogram from electrocardiographic signals of a subject;
- and
- a TWA measuring section which is configured to select a plurality of consecutive waveforms from the electrocardiogram, filter waveforms corresponding to noisy heart beats of the subject from the plurality of consecutive waveforms, and measure a presence of TWA by using the filtered plurality of consecutive waveforms.
A TWA measuring method comprising:
- producing an electrocardiogram from electrocardiographic signals of a subject;
- selecting a plurality of consecutive waveforms from the electrocardiogram;
- filtering waveforms corresponding to noisy heart beats of the subject from the plurality of consecutive waveforms;
- and
- measuring a presence of TWA by using the filtered plurality of consecutive waveforms.
