The afferent pathway of the late response (R2 component) of the blink reflex in response to transcutaneous electrical stimulation of the facial nerve over the stylomastoid foramen remains uncertain. The two major hypotheses regarding the afferent pathway of R2 are that it may consist of either the trigemino-facial or the facio-facial reflex. This study was(More)
A 32-year-old man underwent catheter ablation of an orthodromic atrioventricular reentrant tachycardia. The sinus rhythm electrocardiogram exhibited a normal PQ interval and no delta waves, but atrial pacing produced a prolonged PQ interval and wide QRS morphology with right bundle-branch block due to antegrade accessory pathway (AP) conduction. During the(More)
A 46-year-old man after a tricuspid valve replacement due to traumatic severe tricuspid regurgitation developed cavotricuspid isthmus-dependent counterclockwise atrial flutter. During a linear ablation using a contact force-sensing irrigated ablation catheter, the flutter could be terminated by a radiofrequency application within a deep pouch just below the(More)
The blink reflex excitability recovery curves were studied in 12 patients with postparalytic facial dysfunctions (PPFD) and 12 healthy control subjects. The inhibitory effects of the conditioning stimuli on the ipsilateral R2 and contralateral R2 responses observed in control subjects were significantly less in patients with PPFD. The enhanced recovery of(More)
