Wobbly ECG revisited

The Cardiologist has been very slow at arranging my appointment for the results.  Its now two weeks since the TOE and still no call; I am assuming he is still golfing after the Easter break.

I have been reflecting on the recent Kardia readings showing activity after the T wave.  I found an interesting book; ECG interpretation made incredibly easy, 5th Edition by Lippincott, Williams and Wilkins.   From this, I have discovered there is such a thing as a U wave, which appears to be caused by either by digitalis use or hypercalcemia, which may by a thyroid issue, potentially a side effect of amiodarone.
