The R waves in V5 and V6 are so tall that they are overlapping with the tracing in the channel above. ST segment depression and T wave inversion are seen in inferior and lateral leads. This is a pressure overload pattern which can be seen also in severe systemic hypertension and hypertrophic obstructive cardiomyopathy. In hypertrophic obstructive cardiomyopathy there may be associated prominent Q waves due to septal hypertrophy. In volume overload pattern the ST segment depression and T wave inversion are not usually seen while the R waves will be tall in lateral leads and the T waves upright and tall. A small narrow q wave is also seen in volume overload patterns due to aortic regurgitation or patent ductus arteriosus \/ ventricular septal defect with large left to right shunt. LVH with strain pattern can sometimes be seen in long standing <a href=\"https:\/\/johnsonfrancis.org\/professional\/severe-aortic-regurgitation-echo\/\">severe aortic regurgitation<\/a>, usually with associated left ventricular hypertrophy and systolic dysfunction.<\/p>\n<p>The sensitivity of LVH strain pattern on ECG as a measure of LVH has ranged from 3.8% to 50% in various reports [1].
