Muazzez Isik has donated the above ECG to our website.ĮCG 3b. Serum potassium level was 9 mEq/L while serum calcium level was 7.8 mg/dL.ĮCG signs of both hyperkalemia and hypocalcemia are seen.ĭr. The ECG above belongs to a patient who refused to undergo hemodialysis for 10 days. The serum potassium level is 3.6 mEq/L.ĮCG 3a. The ECG of the same patient after hemodialysis. The pre-dialysis ECG of another patient with serum potassium level of 6.6 mEq/L.ĮCG 2b. Serum potassium level is 4.0 mEq/L.ĮCG 2a. ECG of the same patient immediately after hemodialysis. Serum potassium level is 7.1 mEq/L.ĮCG 1b. ![]() ECG of a chronic renal failure patient immediately before hemodialysis. Ĭhou's Electrocardiography in Clinical Practice. Hyperkalemia must be remembered in the differential diagnosis of wide-QRS tachycardia. Sinus tachycardia in a chronic renal failure patient with hyperkalemia may be erroneously diagnosed as ventricular tachycardia. Giant negative T waves (after treatment of hyperkalemia). Spontaneous conversion of atrial fibrillation įailure to observe these findings do not exclude the presence of hyperkalemia.īrugada-like electrocardiographic patterns The ECG findings of hyperkalemia have low sensitivity and low spesificity. ![]() Sharp, pointed T wave with a narrow base. P wave disappears or decreases in amplitude. ![]()
