Ambulatory ECG recordings have been carried out in five patients suffering from CPH. During the study a total of 105 attacks occurred. Contrary to findings in cluster headache, no typical pattern of heart rate change was found in association with attacks of CPH. A striking finding in all patients, however, was that there were often large and rapid variations in heart rate which could be observed "before", "during" or "after" the attacks. One patient developed bradycardia and sino-atrial block and another bundle branch block together with episodes of atrial fibrillation in association with attacks.
对5例慢性阵发性头痛（CPH）患者进行了动态心电图记录。在研究期间共发生了105次发作。与丛集性头痛的研究结果相反，在CPH发作时未发现典型的心率变化模式。然而，所有患者的一个显著发现是，在发作“之前”“期间”或“之后”，经常会观察到心率有大幅度的快速变化。1例患者在发作时出现了心动过缓和窦房阻滞，另1例患者出现了束支阻滞并伴有房颤发作。
