Can we customize ECG monitor Time using HealthKit?

Hi,

I am doing a research project and would like to get a long-term recording of ECG data. Is it possible to leverage health kit API to enable constant ECG reading longer than 30 seconds? Or it is not possible so that I can only retrieve the default 30-seconds long ECG from the database.

Best,
Brad
