ECG practical

Hello,

We did a practical on the ecg and am a bit confused.

and would be grateful for some help!
one question i got asked
2. are all your calculated values for resting heart rate as listed in data tables 1 and 2 exactly the same? if nor what do the differences indicate (hint: the heart rate is continuosly being modulated at rest)

I'm really not sure could it be something to do with environmental factors?

Thank you!

Movement, body temperature change, urm...random variance...I can't think of much tbh.

Psychological factors like stress vary the RHR. There's one for you!

Are tables 1 and 2 the same person? Or two different people?

Hey Hype :hello:

I assume it was done where the subjects were made to relax for a few mins, and then made to sit whilst being monitored...hence why I didn't mention stress.

I don't get the table 1/table 2 bit...could you this for us, OP?
I chose "stress" as my example since it's the stereotypical psychological factor, but it can be as simple as the "white coat effect", which is what I was mainly thinking of! Subject's HR could easily fall over time as they become a bit more acclimated to being strapped to a running ECG, or even rise for a wide range of thought patterns. :tongue:

If it's two different people, then that opens up a wide range of other factors, hence why we're asking OP! Even if it's the same person separated by a large period of time there are a few more factors that sneak in.
