Correlation of Iatrogenic mild hyperkalaemia and bradyarrhythmia: a problem of polypharmacy in elderly

Mild hyperkalaemia does not typically cause cardiac symptoms. However, for an elderly patient on atrio-ventricular (AV) nodal blocker, even mild hyperkalaemia may result in disastrous outcome. We report a case of persistent bradyarrythmia caused by iatrogenic hyperkalaemia in a patient who had conco...
