Left ventricular hypertrophy can produce specific ECG patterns in precordial leads that mimic myocardial infarction, highlighting the need for careful interpretation to avoid misdiagnosis.
The electrocardiograms of patients in whom myocardial infarction was excluded at autopsy are presented to bring out the following features of left ventricular hypertrophy that may be mistaken for myocardial infarction: (1) QS patterns and/or abnormal RS-T elevation in leads from the right precordium; (2) abnormal Q waves, multiphasic QRS and/or cove plane inversion of the T waves in leads from the transitional zone; (3) prominent Q waves, marked RS-T depression and/or sharply inverted T waves in leads from the left axilla.
