Mapping the critical diastolic pathway in intra-atrial reentrant tachycardia using an automated voltage mapping program.

abstract：INTRODUCTION:Vasovagal reflex is the most common type of syncope but its etiology is not fully elucidated. Venous return and cardiac output are key in hemodynamic control. The aim of the study was to assess cardiovascular biomarkers and echocardiographic measures at rest and during hypovolemia in women with and without...
