ECG changes in Hyperkalemia
Synonym: Hyperpotassemia Definition: Serum potassium (K+) > 5 mEq/l Electrophysiologic basis of ECG changes: In patients with mild hyperkalemia, potassium conductance (IKr) through potassium channels is increased, which tend to shorten the AP duration and on the ECG causing tall tented T waves. With severe hyperkalemia, effect on RMP becomes…
