Does the use of oral contraceptives containing 20 μg ethinylestradiol and 150 μg gestodene influence heart rate autonomic modulation in women?
Third-generation oral contraceptives containing 20 μg ethinylestradiol and 150 μg gestodene do not influence heart rate autonomic modulation, whereas physical activity significantly alters HRV patterns.

Suggests third-generation oral contraceptives may not disrupt cardiac autonomic function; leaves open whether these.
OBJECTIVE: To evaluate the influence of oral contraceptives (OCs) containing 20 μg ethinylestradiol (EE) and 150 μg gestodene (GEST) on the autonomic modulation of heart rate (HR) in women. METHODS: One-hundred and fifty-five women aged 24 ± 2 years were divided into four groups according to their physical activity and the use or not of an OC: active-OC, active-non-OC (NOC), sedentary-OC, and sedentary-NOC. The heart rate was registered in real time based on the electrocardiogram signal for 15 minutes, in the supine-position. The heart rate variability (HRV) was analysed using Shannon's entropy (SE), conditional entropy (complexity index [CInd] and normalised CInd [NCI]), and symbolic analysis (0V%, 1V%, 2LV%, and 2ULV%). For statistical analysis the Kruskal-Wallis test with Dunn post hoc and the Wilcoxon test (p < 0.05 was considered significant) were applied. RESULTS: Treatment with this COC caused no significant changes in SE, CInd, NCI, or symbolic analysis in either active or sedentary groups. Active groups presented higher values for SE and 2ULV%, and lower values for 0V% when compared to sedentary groups (p < 0.05). CONCLUSION: HRV patterns differed depending on life style; the non-linear method applied was highly reliable for identifying these changes. The use of OCs containing 20 μg EE and 150 μg GEST does not influence HR autonomic modulation.

Rebelo et al. (2011) reported a cross-sectional. Oral contraceptives vs. Non-oral contraceptive users was evaluated on Heart rate variability (Shannon's entropy, conditional entropy, and symbolic analysis). The use of oral contraceptives containing 20 μg ethinylestradiol and 150 μg gestodene did not significantly influence heart rate autonomic modulation in active or sedentary women.
