Abstract:

Voluntary cardio-respiratory synchronization VCRS is a technique where an individuals breathing is voluntarily phase locked with hisher heart beat. A signal is generated tone or light from the ECG that is used to pace the breath with a fixed number of heart beats for inspiration and expiration. A small portable device was developed that can create a tone to pace the breathing and record the data for repeated measurements for extended periods of time days or weeks. The device was tested on an individual over a four-week period. Measurements of heart rate variability were made at various times throughout the day for a total of 68 recordings. The data were analyzed to separate out respiratory and non-respiratory induced changes in the heart rate using a unique time domain analysis. The results showed significant variability over the measurement period.
