Heart rate variability in patients with syncopes

P = .002) was featured in HT + PAF subjects (n = 35) when compared with HT-PAF subjects (n = 33). Conclusion: In our study, higher SBP, LA enlargement associated with lower atrial contraction and reduced EF, as well as prolonged P wave, PR, and QT interval durations seem to characterize HT men with PAF. On the contrary, only abdominal obesity and diastolic dysfunction seem to be significant characteristics related to PAF in HT women. These gender differences should be keep in mind for a careful assessment of HT patients to recognize the risk of AF.
