Frequency Domain HRV Intermediate-term HRV
{"Image DocumentName": "Frequency Domain HRV Intermediate-term HRV", "Image ImageDescription": "Very low frequency power (VLF) At ~20 sec-5 min frequency. Reflects activity of renin-angiotensin. system, vagal activity, activity of subject. Exaggerated by sleep apnea. Abolished. by atropine. Low frequency power (LF) At 3-9 cycles/min Baroreceptor influences on HR, mediated by SNS and vagal influences. Abolished by atropine. Renin-angiotensin system \u2013 regulates blood pressure via the kidney. Atropine \u2013 inhibits acetylcholine actions.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
