figure. cardiac monitor showing sinus rhythm on arrival (a) and complete heart block immediately after the head impulse test (b). an electrophysiological study showed no evidence of atrioventricular nodal conduction abnormalities or hypersensitive carotid sinus reflex, and the cardio...
The intricate relationship of the vagus nerve to cardiac function raises concern that vagal stimulation may affect cardiac rhythm and function. Previous pre- and postmarketing studies have not shown this to be a significant problem, with the incidence of bradyarrhythmias reported to be about 0.1%....
Heart rhythm disturbances are also described, most common being a wandering pacemaker [5,6]. Another common finding is the decrease in heart rate as age increases. At fifteen years of age, 70% of the patients present with sinus bradycardia. Atrioventricular block may ...

In a pregnant patient who has CHB with an escape rhythm with narrow QRS complexes and rate of >50bpm, permanent pacemaker implantation can be delayed until after delivery, as described in this case report.SA Heart JournalViljoen, CharleHoevelmann, JulianSliwa, KarenChin, Ashley...
On hospital day 3, the patient spontaneously converted to normal sinus rhythm (heart rate range 108 to 135 bpm), and vasoactive support was weaned. He was asymptomatic during the remainder of his stay and was discharged home on hospital day 5. An echocardiogram at discharge showed normal bi...
Mapping is performed during sinus rhythm, and ablation performed at the site of recording of Kent bundle activation. We describe a case of a patient with Wolff-Parkinson-White syndrome presenting with rapid atrial fibrillation requiring cardioversion. This patient subsequently underwent catheter ablation ...
The rhythm was diagnosed as complete heart block and a permanent pacemaker was inserted. This condition is considered disqualifying for U.S. Navy aviation duty. Conclusion: It is easy to dismiss a single episode of syncope in this age group as due to orthostasis, hangover, or other benign ...

Due to concerns about His-Purkinje disease, symptomaticcomplete heart block without a reversible cause, we placed adual-chamber pacemaker. The patient has not had recurrenceof symptoms since pacemaker implantation. The paced andsensed AV delay values were set at 275 and 250 ms, respec-tively. ...
