How Do Contraceptives and Hormone Replacement Therapy Affect Cardiac Arrhythmias?
Hormonal contraceptives and hormone replacement therapy (HRT) can have varying effects on cardiac arrhythmias. While combined oral contraceptives (COCs) containing estrogen might have a protective effect against some arrhythmias, they can also increase the risk of thromboembolic events. Progestin-only contraceptives are considered safer in patients with a history of arrhythmias. HRT should be used cautiously, especially in postmenopausal women with a history of cardiovascular disease.
