The impact of atrial mechanical function on age‐dependent presentation of neurocardiogenic syncope

The contribution of atrial and ventricular function in neurocardiogenic syncope (NCS) pathophysiology is elusive.We assessed the influence of echocardiographic properties to the age of presentation and NCS recurrences.We assigned 124 patients with symptoms suggesting NCS, to those with syncope initiation at age <35 (group A, n = 56) and >35 years (group B, n = 68). Echocardiographic indices were measured before head-up tilt test (HUTT).A total...
