Three cases who underwent surgery in different areas of the craniofacial region were reported with bradycardia developing intraoperatively during flap traction. Many cases of the oculocardiac reflex during treatment of the orbital region have been reported in the literature. This manuscript recorded that reflex bradycardia can occur during traction or stretching of any structure innervated...

The central cardiovagal mechanism of the medulla oblongata was explored by stimulation and ablation techniques in the anesthetized cat. Insertion of an electrode into the nucleus solitarius (NS) occassionally evoked slight and transient bradycardia, but similar mechanical irritation to the nucleus ambiguus (NA) usually evoked prolonged and intense bradycardia. Electrical stimulation of the dors...

The clinical course of sinus bradycardia and sinus tachycardia has been studied in 735 patients owith acute myocardial infarction admitted to a coronary care unit. Sinus bradycardia was considered to have occurred when two or more records showed sinus rhythm with a rate below 6o a minute, and sinus tachycardia when a sinus rate over 0OO a minute occurred in two or more records. Hospital mortali...

INTRODUCTION Congenital bradycardia-tachycardia syndrome is a rare disorder. Its association with multiple congenital anomalies/mental retardation (MCA/MR) syndrome is exceptional. CASE PRESENTATION We report a case of a new association of MCA/MR with bradycardia-tachycardia syndrome in an 18-year-old Indian man. This syndrome is characterized by mental retardation with delayed development of...

Some otolaryngologists administer topical phenylephrine for bleeding control in adenoidectomy surgery. Absorption of this drug from surgical site can lead to increase in blood pressure due to vasoconstriction and then bradycardia related to baroreceptore reflex.  Our case was an intraoperative arrest of a 9-yrs-old girl related to administration of topical phenylephrine during adenoidectomy how...

OBJECTIVE To estimate the existence and degree of fetal accumulation of acid during end-stage bradycardia as reflected by the base deficit. This may set a criterion for proper intervention during labour. SETTING Maternity unit of the Tel Aviv Medical Centre. SUBJECTS Forty-three consecutively born term infants whose mothers were delivered by vacuum extraction were analysed: 27 because of en...
