Method of normalizing tachycardia ECG based on P-wave and T-wave data interpolation
View Patent ↗The present disclosure relates to a method of normalizing a tachycardia electrocardiogram (ECG) on the basis of P-wave and T-wave data interpolation. The method of normalizing a tachycardia ECG on the basis of P-wave and T-wave data interpolation includes (a) receiving a first ECG signal from a subject, (b) detecting P-wave and T-wave peaks in the received first ECG signal, (c) segmenting the received first ECG signal into one-cycle ECG signals on the basis of the detected P-wave and T-wave peaks, (d) segmenting the one-cycle ECG signals into a P-wave period, a QRS complex period, and a T-wave period, and (e) normalizing the segmented P-wave and T-wave periods through data interpolation.
1. A method of normalizing a tachycardia electrocardiogram (ECG) on the basis of P-wave and T-wave data interpolation, the method comprising:
(a) receiving a first ECG signal from a subject;
(b) detecting P-wave and T-wave peaks in the received first ECG signal;
(c) segmenting the received first ECG signal into a one-cycle ECG signal on the basis of the detected P-wave and T-wave peaks;
(d) segmenting the one-cycle ECG signal into a P-wave period, a QRS complex period, and a T-wave period; and
(e) normalizing the segmented P-wave and T-wave periods through data interpolation.
2. The method of claim 1 , further comprising, before operation (a), receiving a second ECG signal from the subject.
3. The method of claim 2 , wherein operation (e) comprises normalizing the segmented P-wave and T-wave periods according to a cycle of the second ECG signal through data interpolation.
4. The method of claim 1 , wherein operation (b) comprises:
(b-1) detecting an R-wave peak in the received first ECG signal; and
(b-2) detecting the P-wave and T-wave peaks in the received first ECG signal on the basis of a position of the detected R-wave peak.
5. The method of claim 4 , wherein operation (b-1) comprises detecting the R-wave peak by using a Pan-Tomkins algorithm.
6. The method of claim 4 , wherein operation (b-2) comprises detecting a peak in a preset period on a left side of the R-wave peak as the P-wave peak and detecting a peak in a preset period on a right side of the R-wave peak as the T-wave peak.
7. The method of claim 1 , wherein operation (c) comprises segmenting the received first ECG signal into the one-cycle ECG signal on the basis of a preset position on a left side of the P-wave peak and a preset position on a right side of the T-wave peak.
8. The method of claim 4 , wherein operation (d) comprises segmenting the one-cycle ECG signal into the QRS complex period on the basis of preset positions on a left side and a right side of the R-wave peak.
9. The method of claim 2 , wherein operation (e) comprises, when sizes of the P-wave and T-wave periods of the first ECG signal are respectively smaller than sizes of P-wave and T-wave periods of the second ECG signal, normalizing the P-wave and T-wave periods through data interpolation.
10. The method of claim 1 , further comprising, after operation (e), combining the P-wave and T-wave periods, of which data has been interpolated, with the QRS complex period.
11. A computer-readable recording medium in which a program for executing the method according to claim 1 in a computer is recorded.
