Common errors in ECG diagnosis of coronary artery disease.

A variety of clinical conditions not associated with ischemic heart disease can have ECG features mimicking those of ischemic etiology. Some of these entities are: ventricular hypertrophy, intraventricular conduction defects, pre-excitation syndrome, pericarditis, electrolyte disturbances, etc. This can lead to erroneous diagnosis and uncalled for hazardous treatment. A careful comprehensive evaluation with in depth analysis of the ECG can overcome such errors. We have reviewed some of these conditions and elaborated upon the differentiating features.
