comment How does strength of a pulse related to EKG(ECG)?
Great suggestions. Yes, we are interested in the normal heart. I'll test with your suggestions. Thank you.

The paper you shared could be very useful. Thank you again.

comment How does strength of a pulse related to EKG(ECG)?
Thank you for the detailed response! We have a setup where surface of cortex is imaged at high speed, and the image is contaminated by the displacement of the brain. This displacement significantly varies per beat, and we want to remove the effects. EKG and the video are pretty much all we are measuring.

Thanks for the response. Hypertrophy would be a long term effect, right? I am interested in beat-to-beat variability. Do you have a reference for this by any chance? We are sure that it is the displacement of brain due to the heartbeat, and the displacement varies from beat-to-beat. We wish to control it as much as possible, but just wondering if there are better features in ECG that can be used to do so.

@MCM to me it's not a matter of granularity, but fundamental plausibility. I can always improve signal-to-noise ratio, and do signal processing to improve the readings. But is there any signal related to beat strength at all?

@louism Thanks for the interest. I suspect volume would be the best, but pressure or delay could also be useful. Any reference is welcome!

comment What happens once a brain is full?
This answer only talks about short-term aspects, while the original question is about long-term perspectives, I think.

comment The distance the electromagnetic field of the heart can be detected
I heard such anecdotes from electrical engineering friends. Their circuit was so sensitive that you would see your own heart beat on the oscilloscope just in the vicinity. I don't know what the exact distance was. Perhaps you could as this Q at EE.SE electronics.stackexchange.com ?
