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...

introduction takotsubo cardiomyopathy (tcmp) is a rare acute cardiomyopathy characterized by acute chest pain syndrome, similar to myocardial infarction, except that no significant stenosis is observed on coronary angiography in patients with this condition; these findings aid the diagnosis of tcmp. case presentation we discuss an unusual case of tcmp in a 45-year-old woman with complete heart ...

A case of a 71-year-old male with congenital complete heart block is discussed. Patient remained asymptomatic with stable electrocardiograms.
