Cardiopulmonary exercise test is an essential test for deciding appropriate load in cardiac rehabilitation. Even in healthy subjects, vascular vagus nerve reflex may occur upon examination. In order to prevent this symptom, cool down is done after the load, but symptoms of vasovagal syncope are observed at a certain rate. The purpose of this study is to predict the development of vasovagal reflex in cardiopulmonary exercise tolerance test by evaluation of vagus nerve function using heart rate variability.
Others
If we can evaluate the risk of vasovagal syncope in advance, we believe that risks associated with lowering blood pressure and syncope can be avoided.

Fifteen (19.7%) patients had VS during or in the first 5 min after CPX. Seven (9%) patients had symptomatic VS. In the spectral analysis of HRV, significant differences in the normalized low frequency unit (nLF) and normalized high frequency unit (nHF) values were recognized between the two groups. A logistic model identified a significant association between the LF/HF ratio and the occurrence of VS.

We evaluated 76 subjects of 20 to 80 years of age who underwent a CPX in our hospital.
An analysis of HRV was performed 5 min before the CPX with the subject at rest using a portable electrocardiograph. The patients heart rate and blood pressure were continuously recorded during the CPX. VS was defined by symptomatic syncope or a 20 mmHg decrease in systolic blood pressure from the baseline value. Subjects were divided into two groups according to the occurrence of VS during CPX. An autoregressive model was used for the spectral analysis of HRV.
No adverse events
Symptomatic syncope or a 20 mmHg decrease in systolic blood pressure from the baseline value.
