What is ECG feature of Hyperkalemia includes and explain in detail?
(B) Wide QRS complex # ECG is essential and may be instrumental in diagnosing HYPERKALEMIA in the appropriate clinical setting.> ECG changes have a sequential progression of effects, which roughly correlate with the potassium level. ECG findings may be observed as follows:> Early changes of hyperkalemia include peaked T waves, shortened QT interval, and ST-segment depression.> These changes are followed by bundle-branch blocks causing a widening of the QRS complex, increases in the PR interval, and decreased amplitude of the P wave.> These changes reverse with appropriate treatment.>Without treatment, the P wave eventually disappears and the QRS morphology widens to resemble a sine wave. Ventricula' fibrillation or asystole follows.> ECG findings generally correlate with the potassium level, but potentially life-threatening arrhythmias can occur without warning at almost any level of hyperkalemia.> Atrial fibrillation and J waves are not features of hyperkalemia.
