title: Cardiac pacing as emergency care for serious bradyarrhythmia with circulatory shock.
abstract: Three cases of bradyarrhythmia with serious illness of extracardiac organs are reported. Case 1 had sick sinus syndrome. He was admitted to our hospital complaining of syncope and developed apnea. Case 2 had complete atrioventricular block and serious hepatic failure in the hospital. Case 3 had paroxysmal atrioventricular block. He complained of syncope which followed convulsions. Their symptoms might be due to circulatory shock caused by a lazy lower pacemaker from the ventricle. Emergent temporary pacing successfully improved the extracardiac organ dysfunction. Although their bradyarrhythmias were transient, permanent pacemakers were implanted to inhibit the recurrence. A quick temporary pacing should be indicated in patients with critical bradyarrhythmia like our cases for survival.
