May support remote ECG monitoring for sleep apnea; hypothesis-generating pending prospective clinical validation.
The Hurst Exponent of the time series plays a crucial role to differentiate between a sleep apnea patient from a normal patient. They are anti-persistent in nature and the former has more self similarity compared to a normal patient. It has been established that they are AR process and non stationary and Semblance analysis also suggests strong correlation both positive and negative between them. We have proposed tentative mathematical models of the normal and apneal patient using Yule Walker method. This paper illustrates the development of a wireless transmitter system, aimed to transmit low frequency ECG signals over a remote distance. The chief motivation behind this work is to develop a wireless tele-cardiology system, which will be developed to aid the rural health-care management. The transmitter will act as a prime component in the Portable Telecardiology Kit, which is one of the main component of a wireless telecardiology solution for detecting preliminary level cardiac abnormalities.
