A 2 1/2-year-old girl with bradycardia and left bundle branch block at birth began to experience "night cries" when deeply asleep. Electrophysiological study demonstrated congenital diffuse atrioventricular conduction disease with concealed paroxysmal atrioventricular block, nonpropagated His bundle depolarizations, severe sinus node abnormality, and a low atrioventricular junctional escape rhy...
A 52 year old patient presented with orthostatic dizziness and syncope caused by postural heart block. When the patient was supine, atrioventricular conduction was normal but when she assumed the upright posture she developed advanced atrioventricular block rapidly progressing to complete heart block. We are presenting a case of syncope caused by orthostatic heart block.
We describe a 73-year-old woman with a history of breast cancer and metastatic disease diagnosed in January 2002 (stable when we saw her) who was admitted for sudden dyspnea and presyncope. Complete atrioventricular block was documented, and a temporary pacemaker was implanted. Eight hours after admission she recovered sinus rhythm with left bundle branch block as seen in previous recordings. C...
We report the case of a patient followed since childhood for congenital complete atrioventricular block. At 28 years of age, atrioventricular conduction through an accessory pathway with long conduction times was detected. Periods of atrioventricular conduction alternated with periods of atrioventricular block. Sinus tachycardia and 1:1 exclusive conduction through the accessory pathway develop...
INTRODUCTION AND OBJECTIVES The aim of this study was to determine the duration of complete atrioventricular block complicating inferior wall acute myocardial infarction after the administration of fibrinolytic therapy. PATIENTS AND METHOD From 1 January 1992 to 31 January 2002 a total of 449 patients were admitted directly to our hospital with inferior wall acute myocardial infarction in the...
CONTEXT Patients with Alport's syndrome (causing 5% of end-stage renal disease) have a higher risk of heart conduction abnormalities. OBJECTIVE To report a case of Alport's syndrome developing complete atrioventricular block during renal transplantation. CASE REPORT A 21-year-old man with chronic renal failure due to Alport's syndrome was submitted to a renal transplantation under epidural ...
BACKGROUND Supraventricular tachycardia is common after heart transplantation. Adenosine, the standard therapy for treating supraventricular tachycardia in children and adults without transplantation, is relatively contraindicated after transplantation because of a presumed risk of prolonged atrioventricular block in denervated hearts. This study tested whether adenosine caused prolonged asysto...
A 32-year-old man presented with palpitation. He was diagnosed with pulmonary sarcoidosis by lung biopsy. The electrocardiogram showed first-degree atrioventricular block and complete right bundle branch block (CRBBB). We planned to examine laboratory data, echocardiography, Holter monitoring, and gallium-67 scintigraphy. Before he went through all these exams, he developed ventricular tachycar...
