文摘BACKGROUND Classic electrocardiographic manifestations of hyperkalemia starting with peaked symmetrical T-waves are widely recognized in daily clinical practice but little evidence is documented how quickly it can evolve in real-time.CASE SUMMARY An elderly diabetic and hypertensive male presented with acute renal failure and rhabdomyolysis.He experienced cardiac arrest with moderate hyperkalemia despite medical treatment and hemodialysis.Telemetry changes were retrospectively studied and found to have significant rhythm changes that occurred just less than 10 minutes prior to the cardiac arrest.CONCLUSION In hyperkalemia,telemetry rhythm can change instantaneously in a significant way.Rapidly rising potassium could be life threatening and may require more than medical treatment.
