Electrocardiogram

Electrocardiogram changes in renal tubular acidosis is associated with potassium changes.

Hyperkalemia

EKG findings of hyperkalemia associated with renal tubular acidosis include:

  • Interventricular Conduction Delay
    • It is observed when K > 6.5 meq/L
    • Interventricular conduction delay is reflected by QRS widening that are inconsistent with LBBB or RBBB.
  • Sinus Arrest with Accelerated Junctional Rhythm[3][4][2]
  • Ventricular fibrillation

Hypokalemia

EKG findings of hypokalemia associated with renal tubular acidosis include:
