I need to buy a portable HRV monitor to assess vagal tone in infants during several experiments.
I am looking for a new device since the one cited in the studies are mostly old.
Any suggestions?
Thanks a lot
There are various portable devices that measure lead II ECG for computation of HRV. Check out http://vivaquant.com/. They have a new device and good ECG processing.
You may want to try the empatica wristband. It's a bit pricy and does not compute the HRV automatically. But it allows you to receive RR intervals that can be easily used to compute HRV. It also portable and has a long lasting battery. Check it out at https://www.empatica.com/en-eu/research/e4/
you could consider using one of the many apps that link to a smartwatch. For example ithlete. https://www.myithlete.com/
They all require use of a heart rate monitor chest band and this might need modified for infants. There is an old but excellent review paper by Rosenstock (see below) . Alternatively simple, use intermittent rhythm strips as described by and colleagues
