Hyperkalemia masking left ventricular hypertrophy in electrocardiogram in a patient with end-stage renal disease

摘要

A patient of severe chronic renal failure presented with hyperkalemic electrocardiographic (ECG) changes and hyperkalemia. Following a session of hemodialysis, when he reverted to normokalemia, the repeat ECG revealed left ventricular hypertrophy (LVH). Thus we confronted with a situation of hyperkalemia, masking the LVH on ECG initially and when the hyperkalemia was corrected with dialysis the LVH showed in ECG. The plausible explanation for this electrophysiological behaviour was offered.Keywords: Electrocardiography, end stage renal disease, hyperkalemia, left ventricular enlargement
