label: Prominent V1-V2 R wave
label_lc: prominent v1-v2 r wave
description: The R wave in leads V1-V2 is normally considerably smaller in amplitude than the S wave in the same leads. Prominent R wave in these leads implies the R wave is larger than the S-wave, which may indicate cardiovascular pathology. This term includes Tall R wave in lead V1, which is defined by a R/S ratio greater than 1.
