Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Lead V1 has a reading of 9 mmHg and V5 has a reading of 18 mmHg. Does this patient have LVH?
A
Yes
B
No
C
Not enough information
D
None of the above
Explanation: 

Detailed explanation-1: -So in LVH, we expect the ‘R’ waveforms to be enlarged/tall in these leads (conversely, we expect the ‘S’ waves to be deep in the right ventricular leads, that is V1 and V2). Suggested voltage criteria for LVH include: The sum of the S wave in v1 or v2, PLUS the R wave in v5 or 6 ≥35 mm.

Detailed explanation-2: -This condition is caused by changes in genes that cause the heart muscle to thicken. The thickening makes it harder for the heart to pump blood. It can occur even without high blood pressure. People with one parent with hypertrophic cardiomyopathy have a 50% chance of having the genetic mutation for the disease.
