متن کاملHeart rate variability during asymptomatic periods in children with recurrent neurocardiogenic syncope.
Neurocardiogenic syncope (NS) is a common clinical problem during childhood. In order to characterize the autonomic profile in syncopal children, we evaluated heart rate variability (HRV) of 27 patients, ages 8-17 years, in an asymptomatic period. HRV was calculated over a 24-hour (h) period for the time-domain indices and frequency-domain indices. The obtained results were compared to values i...

متن کاملDizziness and slow heart rate during exercise
The ECG at presentation shows an irregular baseline and no P-waves, suggesting atrial fibrillation. A regular multiform ventricular bigeminy with fixed coupling interval can be appreciated, which could be typically seen in digitalis intoxication [1]. Other potential ECG features of digitalis intoxication include decreased AV conduction (because of increased vagal effects on the AV node), possib...
متن کاملRecurrent Postural Vasovagal Syncope
Background—The pathophysiology of vasovagal syncope is poorly understood, and the treatment usually ineffective. Our clinical experience is that patients with vasovagal syncope fall into 2 groups, based on their supine systolic blood pressure, which is either normal ( 100 mm Hg) or low (70–100 mm Hg). We investigated neural circulatory control in these 2 phenotypes. Methods and Results—Sympathe...
