Background: QT dispersion is the interval between the longest QT (QTmax) as well as the shortest QT (QTmin) recorded on a surface 12-lead electrocardiogram. It has a predictive value for ventricular arrhythmias including patients with ischemic heart diseases as well. Coronary slow flow has been always an ambiguous entity on the scale of ischemic heart disease. The predictive value of QT dispersion for coronary slow flow may add a non-invasive tool for the identification of these patients. Objectives: Evaluation of QT dispersion in the prediction of coronary slow flow phenomena in patients having stable coronary artery disease experiencing coronary angiography. Results: In patients having coronary slow flow, QTc dispersion is prolonged. Conclusion:In patients having stable coronary artery disease, QTc dispersion can be employed as a simple non-invasive approach for predicting coronary slow flow; coronary slow flow is not necessarily associated with a benign course, as evidenced by the fact that these patients exhibit a prolonged QT dispersion.

Background: A significant but yet manageable risk factor for cardiovascular disease is hypertension. Increased mortality and morbidity are linked to it. Accurate blood pressure measurement is necessary for the early diagnosis of hypertension and the prevention of its consequences blood pressure (BP). The reading of blood pressure is typically identical in each arm. However, the term "inter-arm difference" refers to the natural occurrence of a reading disparity between the two arms Interarm blood pressure difference (IAD). Objective: To evaluate the incidence of different blood pressure between the two arms and to determine the connection between variations in interarm blood pressure and left ventricle (LV) systolic and diastolic parameters. Conclusion: Since monitoring BP is a straightforward but vital factor in identifying the population most at risk for future vascular events, particularly in HTN patients who appear to have control of their condition, learning It is crucial to know how common IAD is among adults.
