ECG signal analysis for detection of Heart Rate and Ischemic Episodes

Electrocardiogram (ECG) is generally used fordiagnosis ofcardiovascularabnormalitiesanddisorders.Anefficient method for analysingtheECG signal towards the detection ofheartrate(HR)andischemic episodesfollows mainly fivestages:pre-processing, feature extraction,heart ratedetection,beat classification and ischemicepisoderecognition.Theheart rate is calculatedusing theextracted featuresoftheECG signal. Thecalculated HRvaluecan beanalysedforthedetectionofvariouscardiovascularabnormalities.Theabilityof the method wasvalidatedonEuropean ST-T database.Theperformance ofischemic episode detectionshows88.08% sensitivity(Se) and 92.42% positive predictive accuracy (PPA).
