Response of heart rate variability and cardiorespiratory phase synchronization to routine bronchodilator test in patients with asthma
Chin J Physiol. 2021 Jul-Aug;64(4):177-185. doi: 10.4103/cjp.cjp_19_21.ABSTRACTHeart rate variability (HRV) and cardiorespiratory phase synchronization (CRPS) were employed to study the cardio- and respiratory interactions in patients with asthma receiving inhalation of beta2-agonist (Berotec 200 mcg) for routine bronchodilator test. Both time- and frequency-domain parameters were used to analyze the HRV. A weighted G-index was introduced to study the quality of the CRPS. The HRV parameters, in both the time and frequency domains, exhibited significant changes pointing to a sympathetic activation of the autonomic balance i...
