Electrocardiogram (ECG) is one of the most common tests done at the hospitals.In this paper, we aim to develop a method which deploys ECG data to diagnose the sleep ailment, Apnea.A technique deploying wavelet packet transform on RR interval of ECG has been presented.Probability density functions of data, both when Apnea is present and when it Wired is not, are obtained by constructing histograms of decision variable for each signal segment.From the overlapping PDFs of the normal and abnormal cases, a threshold is then derived.

This helped in segregating the Apnea cases from normal cases.The stated method provided a 100% accuracy in diagnosing Sleep Apnea.
