<prompt> Sine wave in ECG is seen in?HyperkalemiaHypokalemiaHypercalcemiaHypocalcemia  <response>: a. HyperkalemiaRef: Nelsons 20e p 357-360Hyperkalemia produces a sequence of changes in ECG:1st ECG finding: Narrowing and peaking tenting of the T wavesQFurther elevation of K leads to AV conduction disturbances, P-wave amplitude widening of QRS intervalSevere hyperkalemia eventually causes with a slow sinusoidal sine-wave pattern followed by asystole.
