Key result
Postexercise 87-lead body surface mapping identified the specific diseased coronary artery in all patients exhibiting type A (LAD), type B (RCA), or type C (LCx) map patterns.
Why the study?
Does 87-lead body surface mapping after treadmill exercise identify the specific diseased coronary artery in patients with effort angina pectoris and single-vessel disease?

Does 87-lead body surface mapping after treadmill exercise identify the specific diseased coronary artery in patients with effort angina pectoris and single-vessel disease?
Postexercise 87-lead body surface mapping can accurately identify the specific diseased coronary artery based on distinct ST-T isopotential map patterns in patients with effort angina and single-vessel disease.
Kubota et al. (1989) conducted an observational in Effort angina pectoris and single-vessel disease (n=21). 87-lead body surface mapping after treadmill exercise was evaluated on Identification of the diseased coronary artery (LAD, RCA, or LCx). Postexercise 87-lead body surface mapping identified the specific diseased coronary artery in all patients exhibiting type A (LAD), type B (RCA), or type C (LCx) map patterns.
