create Cardiac monitor / heart rate monitor/ ECG / EKG wave form?
So how do I create a cardiac monitor https://youtu.be/GVm8pFDxUjU you know those things that stand around in a hospital and go “beep-beep-beep”. How do you advise I animate this?
My problem: I want to have full control over this thing. I want it to show peaks when I need peaks and I need it to be flat when it is supposed to be flat. Any idea what’s the best way to do this? Thanks a million

I have found this tutorial https://library.creativecow.net/articles/rabinowitz_aharon/CC_Heart_Monitor/video-tutorial which I think is pretty great and useful.
Now I just need some help by sorting out my personal brain farts (yes I’ve said it). Here is what I am trying to do: You see a person that’s first calm and then she gets stressed. Should I just animate a normal beep line – it fades it black – swap the picture with a line that has a lot of peeks? Does this make the most sense? Or should I animate 1 normal one, 1 extreme one and 2 in betweens and then I build up tension? What is the best way to go about this? How do those heart monitors work? Does it jump straight to the highest peak? I mean what I could gather is that it monitors the heart rate and displays that with one line, then it refreshes the picture and monitors it again so the line will never move…hmm so should I have a normal line (up down) with a big peak in it all of a sudden???I am just very confused about all this.

I do not have any storyboard or anything like that. I am doing the animation (AE) and the video editing as well. I do not know the footage yet but I have been told “there will be 3 differently coloured waves to show fear, excitement and heart beat. so you will have some footage of a person and their different emotions”. That’s all I know so far and I am not perfectly sure what would be the best way to do this. I guess maybe render out 3 different waves with different peaks and an alpha and combine those?

I know that it will be a woman sitting in front of a computer and she reacts to stuff. There will be 3 lines (sweat, heartbeat, eye movement or something) shown at the same time. Since 3 different coloured lines are supposed to be shown at the SAME TIME (and I do not know how to time all this. Getting the timing right on such a thing sounds very time consuming) I figured I render out a normal version and a version with a lot of peaks for every colour (for all those 3 lines so 6 exports in total) with an alpha channel and then I just swap it from normal mood to extreme mood. That would have been my idea or is there a better way to solve this?
Maybe have an entire graph move from the left to the right and then I mark ALL the ups and downs and just mask it and make it move along for the entire sequence but that sounds like way too much work for editing an entire piece (about 6 minutes) plus graphics in one day.

Still my question is: How would I make something like posted in the video above. How do I make that point follow that line?
