Title:
Clinical and haemodynamic correlates of heart rate variability in children with congenital heart disease | European Journal of Pediatrics
Description:
Heart rate variability (HRV) represents a noninvasive parameter for studying the autonomic control of the heart. Cardiac patients have a complex autonomic disturbance. The relation of HRV to this abnormality in children with congenital heart disease (CHD) has not yet been examined. The present study examined HRV indices from 24 h Holter recordings in 258 children with an operated or non-operated CHD, to determine their differences as an indicator of the severity of heart disease. The latter was defined clinically as New York Heart Association (NYHA) functional class I to IV and haemodynamically by invasive parameters. Five time-domain measures (SDNN, SDNNi, SDANNi, rMSSD and pNN50) and three frequency-domain measures (LF, HF and balance LF/HF) were compared with normal ranges. HRV was reduced in children with CHD, except in patients of NYHA class I. The level of reduction depended on the NYHA functional class. None of the measures was significantly related to haemodynamic data. Conclusion Heart rate variability is reduced in children with Congenital heart disease depending on the functional limitation but not on haemodynamic disturbances. Heart rate variability indices are sensitive markers of the clinical state.

How Does Link.springer.com Make Money? {💸}

We can't figure out the monetization strategy.

Not all websites focus on profit; some are designed to educate, connect people, or share useful tools. People create websites for numerous reasons. And this could be one such example. Link.springer.com might have a hidden revenue stream, but it's not something we can detect.
