How secure (theoretically) would a heartbeat biometric be?

My professor mentioned that heartbeats were unique signatures and ECGs or fitbits that measure your pulse could be used as a biometric, but I’m not as convinced for some reason.

Even if there was a database storing your heartrate over the past month, your current heart rate could be different with time, right? Also I’m guessing that commercial-use devices would be accurate only up to a point?

So yeah, how secure would a heartbeat biometric be? Please me if I’m way off or not, and if there are other threats that I hadn’t considered. Thank you.
