Note. The first column is the name of the record, the second column is the number of R waves marked in MIT-BIH, the third column is the number of correctly detected R waves, the fourth column is the number of falsely detected R waves, the fifth column is the number of missed R waves, the sixth column is the evaluation indicator—sensitivity, and the seventh column is the evaluation indicator—positive prediction rate. According to the AAMIEC38 standard, the difference between the detected QRS complex and the manual mark is within 150 ms, which means that the location detection is successful.
