Implication

Systematic review assesses heart rate variability changes due to sleep deprivation in randomized controlled trials, suggesting potential cardiovascular implications.

Key Points

Sleep deprivation may impair cardiac autonomic function, evidencing significant decreases in RMSSD and increased LF and LF/HF components.
The meta-analysis included 11 studies with 549 participants, showing mixed results for various heart rate variability indices after sleep deprivation.
Randomized controlled trials were evaluated using the Cochrane Risk of Bias tool to ensure methodological quality in assessing heart rate variability.
Further research is necessary to standardize heart rate variability protocols and clarify physiological mechanisms affected by sleep deprivation.
