Objectives and Background

The clinical symptoms of migraine point to autonomic disturbances, especially to disrupted regulation of the circulatory system and autonomic balance. Autonomic nervous system disorders in patients with migraine have rarely been studied and have shown conflicting results. Heart rate turbulence (HRT) has been shown to be an independent and powerful predictor of mortality. The aim is to determine HRT in patients with migraine in comparison with the normal population.


Fourteen patients (mean age: 43±2, thirteen women) with migraine age and sex matched, fourteen healthy subjects (mean age: 47±2, thirteen women) were included to the study. Twenty four hours ambulatory electrocardiography recordings were taken from all subjects (Reynolds Medical Holter System, P700 V8.255). HRT parameters, Turbulence Onset (TO) and Turbulence Slope (TS), were calculated with HRT View Version 0,60-01 software programme from Holter recordings.


There were no significant differences in TO and TS values between migraine and control subjects (TOmigraine: −0,0279±0,092, TOcontrol: −0,0289±0,0076; TSmigraine: 13,5212±3,1267, TScontrol: 16,4252±3,2516, respectively).


HRT parameters which determine the risk of sudden death did not alter in migraine patients.
