Concept for ECG reading of QTc interval

As @Christian_Reich and @mkwong discussed in this thread, we need convention list of concept_ids for measurement. (For ECG and echocardiography and so on). I also plan to convert ECG data into CDM, and I don’t want to use different concept_ids from @vjacob’s.

@Christian_Reich, do you know where we can store these information?
I cannot enter the THEMIS WG I google doc currently (I don’t know why. But possible reason is that I’m in Singapore now.).
