Mitral valve m-mode echo in complete heart block with atrial tachycardia

Mitral valve motion in atrial tachycardia with block.

A 56-year-old man was found to have WolffParkinson-White Syndrome in 1968 after a sudden episode of atrial tachycardia had reverted to normal sinus rhythm. He discontinued maintenance medication and did well until March, 1973, when he presented with a one week history of dyspnea on exertion due to obvious congestive heart failure; he was found to have atrial tachycandia ( atnial nate 240/minute...

Atrial flutter with complete heart block.

The association of atrial flutter and complete heart block is very uncommon. Amongst 168 cases of atrial flutter described by Willius (1927) only one had complete heart block, and in a review of 20,000 electrocardiograms Di Gregorio and Crawford (1939) found the combined dysrhythmia only twice. Campbell (1944) in his analysis of 64 cases of heart block does not mention the association, and of t...

Carbamazepine induced atrial tachycardia with complete AV block.

BACKGROUND/AIM Carbamazepine, a widely used antiepileptic drug that has been used for the treatment of both partial and generalized seizures, for trigeminal neuralgia, as a mood stabilizer and for treatment of neuropathic pain syndromes, may have negative chronotropic and dromotropic effects on the cardiac conduction system. DESCRIPTION OF CASE We report a case of cardiac syncope due to atria...

Hyperkalemia-induced complete heart block

Background: Potassium, as an extracellular ion, plays an important role in the electrophysiologic function of the myocardium and any change in extracellular concentration of this ion might have a marked impression upon myocyte electrophysiologic gain. High serum potassium levels are thought to impair pulse conduction in Purkinje fibers and ventricles more than that in the Atrio...
