Comparative StudyComparison of assessment methods of cardiac vagal modulation.
Several methods have been used to assess cardiac vagal modulation, but there are gaps regarding the association and accuracy of these methods. ⋯ HRV and RSA generated partially redundant results in healthy subjects and in patients with coronary artery disease, while the T4s generated results that were complementary to HRV and RSA in healthy subjects. In addition, RSA and T4s methods were more accurate when discriminating cardiac vagal modulation between healthy subjects and patients with coronary artery disease, when compared to HRV.
