Abstract: The clinical symptoms of myocardial ischemia and infarction are not observable at an earlier stage. Early diagnosis of the same is very crucial to avoid sudden cardiac deaths. Left ventricular dysfunction is a common pathway to various cardiac disorders. Left ventricular dysfunction resulting into inefficient pumping of the oxygenated blood further causes structural and functional changes in the heart. The paper proposes an early, safe, easily deployable, cost effective and non-invasive technique that can be used as confirmative diagnostic tool obtained from 2-lead ECG sample collected for 3-5 minutes duration that diagnoses left ventricular dysfunction. The proposed index derived from Poincare plot of RR interval provides a guideline to the echo-cardiologist and saves his time and also controls inter operator diagnostic variation. Also the test can be performed by paramedical personnel saving the echo-cardiologist's time. The proposed paper lists the results of index of control group, iabetic subjects with and without myocardial ischemia. The index value is found to match the Left ventricular dysfunction diagnosed from echocardiogram findings.
