Abstract

Objective: In this study, we aimed to investigate the presence of atrial volume and decrease in contraction force by measuring left atrial volume and contraction with the head-up tilt table (HUTT) test in patients who were diagnosed with neurocardiogenic syncope (NCS).
Methods: Overall, 45 patients (26 females/19 males, mean age: 26.4±9.2 years) who experienced vasovagal syncope in HUTT (HUTT+) and 40 healthy controls (17 females/23 males, mean age:28.8±10.5 years; HUTT-) were included in the study.
Results: When comparing the groups in terms of left atrial ejection force, there was a significant difference between the HUTT+ and HUTT−vasovagal syncope groups (p=0.05). In both groups, there was a positive correlation between atrial ejection force and left atrial volume (r=0.287, p=0.016) and left atrial volume index (r=0.261, p=0.029).
Conclusion: We showed that the left atrial ejection force and the left atrial volume index were significantly lower in positive vasovagal syncope patients than those in the negative vasovagal syncope patients.
