It is a biofeedback tool that addresses the relationship between respiration and heart rate.
RSA - respiratory sinus arrhythmia.
Paced breathing and HRV measurements from the iPhone camera or a bluetooth HRM.
Also inspired by the work of Dr. Richard Gevirtz.
we have an option to export session data in a simple format that is compatible with KUBIOS.
It writes a list of “TimeStamp RR-Distance” pairs to a textual file that is attached to an eMail message.
