ANALYSIS OF HEART RATE CHANGES IN ANTERIOR AND INFERIOR WALL ST ELEVATION MYOCARDIAL INFARCTION

Maria Noor, Abdullah Bilal, M. Zarrar Arif Butt

An inferior wall myocardial infarction also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel. The basic aim of the study is to analyse the heart rate changes in anterior and inferior wall ST elevation myocardial infarction. This descriptive study was conducted in Health department Punjab during 2019. The data was collected from 100 patients of both genders. All patients of anterior and inferior wall ST elevation myocardial infarction only who got thrombolytic therapy with age range 30-60 of both gender were included. The data was collected from 100 patients of both male and female. Patients with NSTEMI were older than those with STEMI, and presented more often history of hypertension, previous MI and coronary revascularization procedures, and clinical signs of metabolic syndrome. Patients with NSTEMI had greater number of critical coronary stenoses, revascularization was more often incomplete, and such patients presented more often with symptoms of heart failure on initial admission to the coronary care unit. It is concluded that there is no difference among the heart rate variability indices in different type of MI, age group and gender. Data from this study show two major important results, first, that SA can detect differences in cardiac autonomic modulation after primary PCI.
