Idiopathic atrial flutter, high grade atrioventricular block and sino-atrial dysrhythmia in a young man. Effects of exercise testing.
نویسنده
چکیده
A 25-year-old man with idopathic atrial flutter and high grade atrioventricular (AV) block is described. Postcardioversion, sino-atrial (SA) and AV nodal dysrhythmias occurred. Treadmill exercise during atrial flutter increased AV conduction to 2:1, and normalized SA and AV nodal function following cardioversion. A neurogenic basis for these arrhythmias is hypothesized.

This study is of a family with a syndrome of atrial fibrillation or flutter with advanced or complete atrioventricular (A-V) block, involving four members in two generations. Less serious arrhythmias were documented in another 15 members (three generations). Inheritance was by autosomal dominance with varying degrees of expression. An atrial biopsy was obtained in one of the members, a 40-year-...

متن کاملEffects of Diphenylhydantoin on Atrioventricular Conduction in Man By RICHARD
The effects of intravenous diphenylhydantoin (5 mg/kg) on atrioventricular conduction in man at controlled heart rates in the digitalized and undigitalized state were studied. In undigitalized subjects, diphenylhydantoin administration consistently decreased A-V conduction time in each individual subject when identical heart rates were compared. Ouabain infusion produced an increase in A-V cond...

The mammalian sino-atrial node is not a uniform tissue in histological and electrophysiological terms. The differences in ionic currents underlying the regional differences in electrial activity are only just beginning to be understood. One of the ionic currents it is thought to play a role in the center of sino-atrial node for action potential upstroke should be transient Ca+2 current ...
