Vessel heterogeneity of TIMI frame count and its relation to P-wave dispersion in patients with coronary slow flow.

Background: The vessel heterogeneity of thrombolysis in myocardial infarction (TIMI) frame count (TFC) in patients with coronary slow flow (CSF) remains to be further evaluated, and the correlation between TFC heterogeneity and P-wave dispersion (PWD) has not been elucidated. We aim to investigate the vessel heterogeneity of TFC in coronary arteries, and its relation to PWD in patients with CSF and otherwise normal coronary arteries.

Methods: We studied 72 patients with angiographically documented CSF and 66 age- and gender-matched control subjects.
