Web31 May 2024 · Moderately elevated potassium levels (6.0–7.0 mmol/l) typically result in PR interval prolongation, decreased P wave amplitude, disappearance of the P wave, widening of the QRS complex or conduction blocks with escape beats, while severe hyperkalemia (> 7.0 mmol/l) may induce ventricular fibrillation and asystole on the ECG [ 3 ].
WebThe first two cases demonstrated the most common changes associated with hyperkalaemia of (1) tall peaked T-waves (2) reduction in amplitude and eventually loss of the P-wave and (3) bizarre widening of the QRS interval (table 1, fig 5 B–D). These ECG changes can be explained by the electrolytes physiological effect on myocardial cells.
