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...
متن کاملAtrial flutter with exit block.
The mechanism of atrial flutter is controversial. A 76-year-old woman with rheumatic heart disease was referred to our clinic with an unusual rhythm disturbance which initially appeared to be classic atrial flutter at a rate of 300 beats/min. Later tracings, however, demonstrated a rate exactly one-half that of the earlier ECGs, with an identical p-wave morphology and vector. This latter rhythm...
متن کاملHyperkalemia-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...

متن کاملAtrial tachysystole (flutter?) with apparent exit block.
A case of atrial tachysystole with apparent exit block is reported in which the basic cycle length of atrial activity is 260 msec. Simultaneous right intra-atrial electrograms show cycle lengths of 510 to 780 msec which are roughly multiples of 260 msec establishing the diagnosis of exit block. Rapid atrial stimulation (1,200/min) to overdrive the rapid ectopic atrial pacemaker was only transie...
