WebThe patient’s ECG shows a wide QRS complex and peaked T waves concerning for hyperkalemia. Appropriate treatment with calcium gluconate, insulin, and dextrose is initiated empirically. The laboratory values show a potassium of 7.1 mEq/L with a serum creatinine of 4.6 mg/dL. Nephrology is consulted for hemodialysis. WebThe normal T-wave. Assessment of the T-wave represents a difficult but fundamental part of ECG interpretation. The normal T-wave in adults is positive in most precordial and limb leads. The T-wave amplitude is highest in V2–V3. The amplitude diminishes with increasing age. As noted above, the transition from the ST segment to the T-wave ...

WebDec 22, 2024 · Hyperkalemia is a condition that can cause peaked T waves. Depending on the degree of hyperkalemia, the peaked T-waves may range from a low amplitude to tall peaks to a sinusoidal pattern on ECG. The mechanism of the T-wave morphologies is through inhibition of the positively charged extracellular potassium on repolarization of … WebMar 8, 2024 · Peaked T waves generally occur when potassium levels are about 5.5-6.5 mEq/L.
