ECG signals are used to diagnose it. This study aims to eliminate signal noise by converting available wavelets and extracting existing waves. The location-related properties and amplitude of these waves will be extracted to develop a model based on the random forest algorithm for training and evaluating the algorithm.</span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span sans-serif="" style="font-family:Calibri,"><b><span style="font-size:12.0pt"><span new="" roman="" style="font-family:" times=""><span style="color:#2f5496">Materials & Methods:</span></span></span></b> <span style="font-size:12.0pt"><span new="" roman="" style="font-family:" times="">This study uses the MIT-BIH dataset, which contains digital ECG signals extracted from Holter bands for different patients at Arrhythmia Hospital from 1975 to 1979. The study applies signal processing and machine learning techniques to classify ECG signals and identify heart patients. The MATLAB software implemented the algorithm, which was evaluated based on accuracy, error rate, TP, FP, Precision, Recall, F-Measure, and ROC criteria. These criteria were determined by a confusion matrix.</span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span sans-serif="" style="font-family:Calibri,"><b><span style="font-size:12.0pt"><span new="" roman="" style="font-family:" times=""><span style="color:#2f5496">Results:</span></span></span></b> <span style="font-size:12.0pt"><span new="" roman="" style="font-family:" times="">The study results and comparisons demonstrate that the proposed method is highly effective in detecting heart patients.
