P-wave duration and dispersion in patients with coronary slow flow and its relationship with Thrombolysis in Myocardial Infarction frame count

Use of the TIMI frame count in the assessment of coronary artery blood flow and microvascular function over the past 15 years

“…P-wave dispersion and P-wave duration both were found to be greater among patients with coronary slow-flow phenomenon than among controls. They found a significant positive correlation between PD and mean TFC (r = 0.806, respectively; P \ 0.0001) [36]. With respect to the ST segment, among patients undergoing primary PCI for ST elevation myocardial infarction, a significant correlation between post PCI CTFC and persistent ST segment elevation has been demonstrated (r = 0.4, P \ 0.05) [37].…”

The increase in P-wave dispersion is associated with the duration of disease in patients with Behçet's disease

“…Prolonged P-wave duration and PD have been reported to represent an increased risk for atrial fibrillation (AF) in patients with no underlying [5,6]. Increased Pmax and PD are also related with stable angina pectoris [7], acute coronary syndromes [8], coronary slow flow phenomenon [9] and those undergoing coronary artery bypass surgery [10]. Although, there are few studies that demonstrated the electrical irregularity in patients with BD [10], to our knowledge, this is the first study evaluating PD in those patients.…”

Prediction of Reperfusion and Infarct Related Artery Patency after Thrombolysis in Acute Anterior Myocardial Infarction by Degree of P Wave Dispersion on ECG

“…10 P wave dispersion was significantly higher in 60 patients with paroxysmal lone AF than in 40 healthy controls (p <0.0001) in another study. 13 The multivariate regression analysis of odds ratios for characteristics of the subjects likely to cause IRA patency was studied. Out of the 5 variables, PWD120 was found to be the significant predictor of ST segment resolution as well as IRA patency.…”
