- I really have to control for potential confounders. There are a lot of things that influence our rate variability. Dan quinceanera, who's an expert in heart rate variability sort of gets this nice graph, you have to consider caffeine intake. cemetry medications such as beta blockers or alpha blockers, for instance, depress antidepressants, TCAS can also affect it. Alcohol consumption, time of day exercise, food intake, water intake, and also bladder filling could also play a role.
- This is why when you're doing autonomic nervous system testing at the hospital, you have a very detailed procedure. In order to prepare for the autonomic nervous system. You have to you know, stop a lot of these medications 48 hours before some of it 24 hours beforehand, no alcohol analgesics 12 hours before in the morning, I have no support stock, these don't presets no confined clothing, and then three hours before no nicotine, coffee and food. So you have to take these into consideration when you're doing research when incorporating heart rate variability.
- So my recommendations for Heart Rate Variability you really wants to obtain however, commercials in identical settings. This means same time, same posture, environment, activity, extract, etc. To avoid potential confounders. If you're not able to account for this or control it, then at least record them and then account for other potential factors like whether you're stressed type of meals, sleep, Thompson quality, etc. Accounting for these things really make the heart rate variability of data that you collect useful.
- The other thing I mentioned is incorporate heart rates along with heart rate variability, because sometimes they have different information. And the final thing is you the next last thing is it's better to choose within person versus between person analysis because there's a lot of variability that happens between individuals so you want to follow variability over time. And then you want to consider including electric thermal measurements as to this is the answer to hoppings question. You could use the skin conductance measures as another way to assess sympathetic nervous system. So the final summary 1980's in 2000, saw major advances in cardiovascular care.
- Heart Rate Variability was and remains the most practical means to assess the autonomic nervous system. Heart Rate Variability lost his prognostic usefulness for post mi mortality with the advent of modern cardiovascular care. But however, it still may be useful for diagnostic diagnosis of diabetic autonomic neuropathy and overall autonomic function. And many factors influence heart rate variability, accounting for these factors will influence or improve your heart rate variability usefulness in your research. And then that's it
