Abstract:
The trigeminal autonomic cephalalgias (TACs) are characterized by the cardinal combination of short-lasting unilateral pain and autonomic phenomena affecting the head, including cluster headache, paroxysmal hemicrania and SUNCT. Infrequently reported have been cases with dissociation of these two cardinal features- usually with autonomic phenomena without pain, rather than the reverse. Herein is described the case of a 56-year-old man presenting with an unusual form of TAC resembling chronic paroxysmal hemicrania but with a lower frequency of occurrence, with temporal features not typical of previously described TACs, and consisting of severe unilateral head pain without any autonomic symptoms or signs, absolutely responsive to indomethacin.

Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism, and...
