It seems a "feminine pattern", a previous ECG could help. Another option is that the electrodes where placed not exactly in the same spot (is compared to previous ECG's). T waves are asymmetrical, there is no ST down or up-sloping and the QT interval (measured and corrected) is normal. I would say that these are non-significant changes.
I think that a previous ECG could help in the analysis. In any case, ST depression is not significant, there is a negative T wave in V2, but it's important either the comparison with previous ECG or the electrodes position. I dont' think any correlation with amiodarone therapy (QTc is normal).
Only the first beat in V3 has a negativ T, I would repeat the ECG. I think these negative T-waves are normal and the variation from a former ECG is depending from the location of the electrodes.
Probably not. But the more important question is whether or not the patient has had a stress test (imaging), and if there are any significant symptoms.
In my opinion, these ECG changes may be related with the use of amiodarone. Although ECG is not specific to the electrophysiologic effects of amiodarone (prolonged QT etc.), this may be a manifestation of amiodarone-induced hypothyroidism. Therefore, the patient must be examined for thyroid function.
I agree with Timothy. It is important to follow up this patient. V2-V3 abnormalities sometimes can offer early signs for ischemia, e.g. Wellens syndrome http://en.wikipedia.org/wiki/Wellens'_syndrome
