How to Recognize Regional Wall Motion Abnormalities on Echocardiogram?

Echocardiography is only next to ECG in the investigations used in modern day emergency departments for evaluation of coronary artery disease and myocardial infarction. Though troponin estimation is needed for final confirmation of myocardial injury, it takes time to get a standard troponin report. Emergency management can be initiated much before that with the help of echocardiography and ECG. Regional wall motion abnormality is the hallmark of coronary artery disease in this scenario. Though there are other causes like myocarditis and stress cardiomyopathy, by and large, coronary artery disease is the most important cause of regional wall motion abnormalities.
