Percutaneous transluminal coronary angioplasty as a model of cardiac ischemia: Clinical and modelling studies.

摘要: Percutaneous transluminal coronary angioplasty (PTCA) is a palliative therapy for artery disease in which balloon-tipped catheter inserted into partially occluded and inflated to pressures of 4-12 bar durations 10-300 s. The resulting block antegrade blood flow provides an experimental model ischemia has been studied this dissertation. technique body surface potential mapping (BSPM) was used continuously record 117-lead ECGs from patients undergoing PTCA; isointegral maps recorded before inflation the balloon were subtracted those during produce difference maps. Based on these maps, inflations could be separated groups corresponded had dilated.
