ABSTRACT

ECGs are important biomedical signals, which are reflective of an electric activity of the heart. They form a subject of intensive research for over 100 years. ECG conveys information regarding the electrical function of the heart, by altering the shape of its constituent waves, namely the P, QRS, and T waves. ECG Feature Extraction plays a significant role in diagnosing most of the cardiac diseases. One cardiac cycle in an ECG signal consists of the P-QRS-T waves. This feature extraction scheme determines the amplitudes and interval in the ECG signal for subsequent analysis. The amplitude and interval of P-QRS-T segment determine the function of heart. This paper reviews the 55 patients ecg and shows the abnormalities related with sex, age, food habit. This ecg result shows more than 45 age peoples are affected by heart problem. When compare to vegetarian, non vegetarians affected with cardiac problems. Patients with piles, urinary bladder disorders, chest pain, stomach pain, tumour, tiredness, thyroid, kidney problem, uterus problem, leg lesions also shows abnormal ecg levels like short PR intervals, ST depression, Sinus tachycardia, long QT interval, T wave abnormality, anterior myocardial infarction, abnormal sinus bradycardia, abnormal left axis deviation.

Keywords: ECG, Tachycardia, Bradycardia, myocardial infarction, kidney disorders.
