ECG app not working on Apple Watch

I cannot get the ECG app to take a reading. Sometimes it starts and gets all the way down to a few seconds left, then restarts at 30 seconds. I have tried restarting twice and it still doesn't work. Any suggestions?

Pairing the watch again with your iPhone, setting it up as a new device, would be the next step to rule out a software issue:
