Detailed explanation-1: -After age 40, a third heart sound is usually abnormal and correlates with dysfunction or volume overload of the ventricles. Any cause of ventricular dysfunction, including ischemic heart disease, dilated or hypertrophic cardiomyopathy, myocarditis, cor pulmonale, or acute valvular regurgitation, may qualify.
Detailed explanation-2: -New ST-segment elevation of 1 mm (0.1 millivolt [mV]) or more in two or more limb leads (or precordial leads V4-V6) or by 2 mm or more in two or more precordial leads V1-V3) can indicate myocardial injury. Locating the “J” point is helpful in determining if the ST segment is elevated.
Detailed explanation-3: -Ventricular Aneurysm There is ST elevation with deep Q waves and inverted T waves in V1-3. This pattern suggests the presence of a left ventricular aneurysm due to a prior anteroseptal MI.
