Does body surface mapping detect specific QRS changes indicating regional myocardial conduction delay during PTCA-induced ischemia?

Population

25 patients undergoing percutaneous transluminal coronary angioplasty (PTCA), including 20 with one-vessel disease and 5 with two-vessel disease.

Intervention

Body surface mapping (BSM) using a 62-lead radiotransparent electrode array during balloon inflation.

Comparator

BSM before and after balloon inflation.

Outcome

Specific changes in the QRS complex and QRS integral maps during ischemia.surrogate

Body surface mapping during PTCA reveals specific QRS changes indicative of regional myocardial conduction delay during acute ischemia.
