Abstract:This paper proposes a method for decomposing heart rate fluctuations into background, respiratory and blood pressure oriented fluctuations. A signal cancellation scheme using the adaptive RLS algorithm has been introduced for canceling respiration and blood pressure oriented changes in the heart rate fluctuations. The computer simulation confirmed the validity of the proposed method. Then, heart rate fluctuations, instantaneous lung volume and blood pressure changes are simultaneously recorded from eight normal subjects aged 20-24 years. It was shown that after signal decomposition, the power spectrum of the heart rate showed a consistent monotonic 1/fa type pattern. The proposed method enables a clear interpretation of heart rate spectrum removing uncertain large individual variations due to the respiration and blood pressure change.

Estimation of Heart Rate Variability Fluctuations by Wavelet TransformTechnique for separate estimation of fast and slow fluctuations in the heart rate signal is developed. The orthogonal dyadic wavelet transform is used to separate the slow heart rate changes in approximation part of decomposition and fast changes in detail parts. Experimental results using the recordings from persons practicing Chi meditation demonstrated the applicability of estimation heart rate fluctuations with the proposed approach.

Purpose: To evaluate the effects of passive music therapy on anxiety and vital signs among lung cancer patients at their first peripherally inserted central catheter placement procedure in China. Methods: A randomized controlled clinical trial was conducted in the cancer center of a hospital in Chengdu from May to December 2017. A total of 304 lung cancer patients who met the inclusion and exclusion criteria were recruited and randomly assigned to experimental ( n = 152) and control ( n = 152) group, respectively. The control group only received standard care, while the experimental group received standard care and passive music therapy during peripherally inserted central catheter placement (30–45 min) and after catheterization, until discharged from the hospital (twice a day, 30 min once). Measures include anxiety and vital signs (blood pressure, heart rate, and respiratory rate). Results: Repetitive measurement and analysis of variance showed that the patients in experimental group had a statistically significant decrease in anxiety, diastolic blood pressure, and heart rate over time compared to the control group, but no significant difference was identified in systolic blood pressure and respiratory rate. Conclusion: Passive music therapy can efficiently relieve the anxiety of lung cancer patients during peripherally inserted central catheter placement. It also can lower the patient’s diastolic blood pressure and slow down the heart rate. So, music therapy benefits patients with peripherally inserted central catheter.
