Respiratory sinus arrhythmia in cluster headache syndrome

Headache
P Kruszewski

Abstract

Respiratory sinus arrhythmia is regarded as indicative of cardiac vagal integrity. A ratio of the longest R-R interval to the shortest R-R interval during deep breathing test (E:I ratio) was calculated in controls (n = 49), cluster headache (n = 33) and CPH (n = 4) patients. E:I ratio decreased with age but was not dependent upon sex or upon smoking habits. Furthermore, there were no significant differences as regards E:I ratio between cluster headache patients in and outside a bout, or between patients with right-sided and left-sided headaches. However, the E:I ratio was found to be significantly lower in the cluster headache group as such, when compared with controls, but the number of patients disclosing pathological or borderline results was small, 2 and 2, respectively. This may indicate that a putative vagal dysfunction in cluster headache is usually less marked than in patients with e.g. diabetic autonomic neuropathy. Significant attack-related changes in the E:I ratio were detected in all individual patients though these changes were not of a uniform nature from individual to individual. E:I ratios were rather high in 3 out of 4 CPH patients examined. However, the number of patients in this group is too small to allow d...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
