Investigation of the Risk of Sudden Cardiac Death Using Heart Rate Variation in Migraineurs

Objective: Migraine is an episodic syndrome that results from dysfunction of the sympathetic nervous system and consists of various clinical features. The aim of our study is to evaluate the risk of sudden cardiac death and autonomic dysfunction in patients with migraine by heart rate turbulence (HRT) and heart rate variability (HRV). In addition, it is aimed to inform patients about their cardiovascular risks. Material and Method: A total of 77 individuals, 35 of whom were chronic migraine sufferers and 42 healthy individuals, who were followed up by the neurology clinic over the age of 18 and under the age of 70, were included in this study. A 24-hour holter recording was made for all participants. Heart rate variability and heart rate turbulence parameters were calculated using European Society of Cardiology studies. Findings: A significant difference was found between the migraine and control groups in terms of Tonset measurements (p=0.004). There was no statistically significant difference in terms of other variables. Conclusion: Our findings showed that Tonset, one of the heart rate turbulence parameters, was associated with autonomic function in patients with migraine, whereas heart rate variability parameters were not associated with autonomic dysfunction in patients with migraine.
