Takes an ECG waveform and using "findpeaks" function thresholds and detects the QRS complex along with the PT peaks.
Also finds RR and QRS complex interval and heart rate in BPM.

未定义与 'double' 类型的输入参数相对应的函数 'lowpass'。
出错 ECG_PQRST_Revised (line 33)
[ecg1,d]= lowpass(ecg2,9/(fs/2)); %filtering (keep same) vary with dataset
a and b are notch filter coefficients.
this code is not based on any specific algorithm.
I have used thresholding to detect P,Q,R,S and T peaks of an ECG waveform.
what is meaning b and a
