background: complete atrioventricular block (av block) is a serious complication of slow pathway ablation therapy in the treatment of atrioventricular nodal re-entrant tachycardia (avnrt).   the present study was aimed at determining whether the electroanatomical pace mapping of koch’s triangle could significantly improve the safety, efficiency, and efficacy of selective slow pathway ablation i...

in human several kinds of electrocardiographic findings have been reported in association with pneumothorax such as decreased and/or alternating qrs amplitude (electrical alternans). however, electrocardiographic changes concurrent with pneumothorax have rarely been discussed in veterinary literature. a 3-year-old male crossbreed dog was presented with a history of car accident. thoracic au...

the coronary slow flow phenomenon (csfp) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. although the relation between the csfp and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the csfp and the conduction system disorder. in this case report, we describe a patient with the csfp ...

OBJECTIVE The purpose of this work was to analyze outcome with focus on growth in infants fetally exposed to heart block-associated maternal anti-Ro52/SSA autoantibodies and identify maternal factors other than the autoantibodies increasing the risk of fetal heart block. PATIENTS AND METHODS Thirty-two pregnancies in 30 anti-Ro52-positive mothers were included. Seven fetuses developed second-...

A 63 year old man with complete atrioventricular block was diagnosed as having Fabry's disease. A short PR interval is a common electrocardiographic finding in Fabry's disease, but complete atrioventricular block is a very rare complication. Necropsy indicated that lipid accumulation in the atrioventricular conduction system was the probable cause of this patient's atrioventricular block.

Paroxysmal atrioventricular-block is a poorly-recognized cause of atrioventricular conduction abnormality leading to syncope and can be fatal. Here we report a case of paroxysmal atrioventricular-block presenting as syncope treated effectively with pacemaker implantation and review the current literature on prevalence, known mechanisms and treatment for it. Importantly we provide the diagnostic...

INTRODUCTION Acute ethanol ingestion can prolong the PR interval, but searching Medline, we have found only one report of Wenckebach-type atrioventricular block in ethanol poisoning. We present a high-degree atrioventricular block in an ethanol-poisoned patient. CASE PRESENTATION A 17-year-old woman with a non-contributory medical history ingested 3dcl of vodka and was found comatose. On arri...
