Compute_Hr function miscalculates.

I am working on the MIT-BIH records. The aim is to calculate the Heart Rate and find the maximum, minimum and the mean of the Heart rates. I extracted the ECG signal from the record, calculated the QRS peaks and calculated the Heart Rates using the compute_hr function from the wfdb package. Similarly extracted the QRS peaks from the annotation file and calculated the Heart Rates using the compute_hr function from the wfdb package. For the 101 record, the maximum Heart Rate from the annotations is 900.00bpm while the calculated qrs indices gave a maximum Heart rate of 111.3402bpm. I have this issue with many other records.

Python code:

record = wfdb.rdrecord(record_path, channels=[0])                                                                                                                                                                 
ann_ref = wfdb.rdann(record_path,'atr')
qrs_inds = processing.gqrs_detect(sig=record.p_signal[:,0], fs=record.fs)

heart_rate_wfdb = processing.compute_hr(sig_len=record.p_signal.shape[0], qrs_inds=qrs_inds, fs=record.fs)
heart_rate_wfdb = heart_rate_wfdb[np.logical_not(np.isnan(heart_rate_wfdb))]
heart_rate_min = "{0:.4f}".format(np.amin(heart_rate_wfdb))
heart_rate_max = "{0:.4f}".format(np.amax(heart_rate_wfdb))
heart_rate_mean = "{0:.4f}".format(np.mean(heart_rate_wfdb))

ref_heart_rate_wfdb = processing.compute_hr(sig_len=record.p_signal.shape[0], qrs_inds=ann_ref.sample[1:], fs=record.fs)
ref_heart_rate_wfdb = ref_heart_rate_wfdb[np.logical_not(np.isnan(ref_heart_rate_wfdb))]
ref_heart_rate_min = "{0:.4f}".format(np.amin(ref_heart_rate_wfdb))
ref_heart_rate_max = "{0:.4f}".format(np.amax(ref_heart_rate_wfdb))
ref_heart_rate_mean = "{0:.4f}".format(np.mean(ref_heart_rate_wfdb))`

Can someone tell me what is that I am doing wrong?

processing.compute_hr のエントリーポイントから開始し、issue にある record 101、qrs_inds、ann_ref.sample[1:] を使って比較を再現してください。2 つの QRS インデックス入力によって心拍数の極値がどのように異なる結果になるかを確認してください。不一致が説明され、確認された不具合があれば回帰テストでカバーされれば完了です。
