Evaluation of Cardiac Autonomic Function in Patients With Alteration in Thyroid Hormones: Systematic Literature Review
Authors' conclusion
Both hypothyroidism and hyperthyroidism affect cardiac autonomic modulation, resulting in a reduction in heart rate variability. However, there were differences in relation to the availability of frequency and time data.

Pooled result
As reported in the abstract
- Patients with hypothyroidism or hyperthyroidism have reduced heart rate variability, reflecting decreased adaptive capacity of the heart
