It's OK: Rule of Thumb is in general we consider QTc of 480+ as something to look at, and even some might consider more than 500 as significant

Punt: Leave the interpretation of your ECG to a cardiologist and the appropriateness of continuing on medication to the prescribing doc. In general, see: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3940069/
