EKG examples
EKG below demonstrates R in V5 is 26mm, S in V1 in 15mm. The sum is 41 mm which is more than 35 mm and therefore LVH is present according to the Sokolow-Lyon criteria.
EKG below demonstrates left ventricular hypertrophy according to the Sokolow-Lyon criteria
EKG below is an another example of extreme left ventricular hypertrophy in a patient with severe aortic valve stenosis
EKG of a patient with LVH and subendocardial ischemia leading to positive cardiovascular markers in blood testing
EKG below shows features of Left ventricular hypertrophy in individual lead
EKG BELOW shows sinus rhythm with P waves that are terminally negative in V1 which is suggestive of left atrial abnormality. There is a tall R wave in V5 greater than 30 mm., a deep S wave greater than 30 mm. in V2, and an R wave in lead II greater than 20mm. There are diffuse ST/T wave changes. All of these finding suggest left ventricular hypertrophy. This woman in fact has IHSS.
The rhythm in the EKG shown below is not clear. It could be sinus with very flat P waves (there are prominent U waves that make it difficult to see P waves) or perhaps nodal rhythm, with most likely ventricular premature complexes. There is a right axis deviation of the QRS and tall R waves in V5 (> 35mm) with wide spread ST changes. The EKG suggest left ventricular hypertrophy with possibly a left posterior fascicular block.
