The phase image: its relationship to patterns of contraction and conduction.

摘要: To determine the relationship of phase changes and abnormalities ventricular contraction conduction, we performed image analysis blood pool scintigrams in 29 patients. Eleven patients had no evidence or ECG conduction abnormalities, four seven abnormal both variables. The delay generally related to degree abnormality. mean hypokinetic segments differed from that normokinetic same patient (p less than 0.025), akinetic dyskinetic 0.001) 0.005), but there was a significant overlap normal segments. Also, with minimal associated regional presented dispersion pattern consistent different normal. A single study at rest stress demonstrated effect heart rate on assessment confirmed independent effects delay. Acquisition analytic methods should add significantly resolution method.
