Question: what does voltage criteria for left ventricular hypertrophy mean?
Answer: 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.
