In cardiovascular care, it most often refers to vagal (vagus nerve) effects on heart rate and rhythm. It is commonly discussed when interpreting heart rate variability, fainting episodes, and certain arrhythmias. It can also be used as a general marker of autonomic balance alongside sympathetic activity."}
