Electrocardiography transmits information about the electrical function of the heart by changing the state of its component waves, namely the P, QRS and T waves, which represent one cycle of the heart. The amplitude and interval of the P-QRS-T segment determine the function of the heart. Cardiac arrhythmia manifests itself as a state of abnormal electrical activity in the heart, which is a hazard to humans. Currently, the onset of ischemic cerebrovascular disease is associated with electrocardiographic changes in patients who did not have primary heart disease. Aim: We estimated the frequency of electrocardiographic changes to be remarkable. The aim of the study is to analyze heart disease in electrocardiogram (ECG) signals for cardiac arrhythmias that lead to ischemic stroke, using the result of normal and abnormal ECG waves. Methods: Study sample of 75 patients which had been admitted to the Cardiology department of PIMS Hospital Islamabad for one-year duration from March 2019 to March 2020. A 12-lead resting ECG was performed on all patients, using Cardiofax S ECG-1250K for high-level 12-lead analysis. All records were translated by a similar person who is a cardiologist who did not know the medical history of the subject. In particular, the following ECG abnormalities were looked for: ST segment elevation or depression, T wave aberration (inversion or high T wave), bundle branch block, left ventricular hypertrophy (LVH), arrhythmia, QT wave lengthening, and other changes. In the results of 75 patients, approximately (58.67%) were men, and (41.33%) women, their mean age (62 years). The control group consisted of (52%) men and (48%) women, mean age (61.5 years). The frequency of electrocardiographic changes in the study group was (58.67%), while in the control group - the patient (25.33%). Key words: Arrhythmia, Cardiac ischemia, Resting ECG, Ischemic Stroke, ST Segment depression.
