Atrial interval based heart rate variability diagnostic for cardiac rhythm management system

摘要

A cardiac rhythm management system acquires atrial heart rate variability data. The system provides a graphic or other indication of patient well-being based on the atrial heart rate variability data. Such atrial heart rate variability information provides an indication of the autonomic balance between the sympathetic and parasympathetic/vagal components of the autonomic nervous system. One example of the system also provides time-domain processing of frequency components of the atrial heart rate interval signal to obtain the indication of patient well-being.
