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...

متن کاملParoxysmal Heart Block in Bundle Branch Block.
When a patient is suspected of having Stokes-Adams disease the electrocardiogram is of critical importance, particularly in respect of the auriculo-ventricular (A-V) conduction time. Should this not be prolonged, the possibility of paroxysmal heart block remains, although the diagnosis of Stokes-Adams disease is uncertain without some degree of heart block recorded graphically. It is not known ...
متن کاملTransient Left Bundle Branch Block due to Severe Hyperkalemia
Hyperkalemia is a potentially life-threatening electrolyte imbalance that can lead to sudden death from cardiac arrhythmias and asystole. We present a case of transient left bundle branch block pattern on an electrocardiogram (ECG) secondary to hyperkalemia in a patient with history of end-stage renal disease. A 52-year-old man presented to the emergency room (ER) with chief complaints of weakn...
متن کاملComplete heart block induced during cardiac catheterization of patients with pre-existent bundle-branch block. The hazard of bilateral bundle-branch block.
or bundle of His. Blockage of both the right and left bundle branches would be tantamount to block at these locations. This is the well-established concept of bilateral bundle-branch block.1-3 It highlights a hazard inherent in catheterization of the ventricle opposite that which is already the site of bundle-branch block. Since the advent of cardiac catheterization, numerous reports have been ...
