Normal limits (96% range) for STonset (STo, the J-point amplitude) in vessel-specific bipolar left anterior descending (LAD), left circumflex (LCX) and right coronary artery (RCA) leads and in chest leads V1-V6 for the combined group of women. Bipolar LAD lead is recorded from 1/2 interspace below V8 to V3, LCX from 1/2 interspace above V2 to 1/2 interspace above V8, and RCA 1 interspace above V2 (at third interspace) to left iliac crest. Electrode placements for limb leads are the same as for Mason-Likar leads and V3-V6 positions for monitoring leads are at the level of V1 and V2.
