Paper Title - Automatic Detection of Heart Disease Using Spatial Velocity


Abstract
Computer aided automatic ECG signal processing has drawn significant attention of the researchers over the past decade or so. Identifying the features of ECG signals such as peaks, the intervals and the segment has been one of the major area of research in one dimensional ECG signal processing. An accurate and proper estimation and detection of this features can help in better diagnosis of heart related diseases such as arrhythmia and so on. Even though there have been several previous studies that have proposed different techniques for efficiently detecting ECG properties, very few works have suggested simultaneous feature extraction from all twelve lead of data and integrated this features into a decision making process . In this work we have proposed a novel ECG signal processing and feature estimation technique by combining time domain windowing technique with spatial velocity and FFT. First we filter the signals with rectangular window and separate out the improper frequency band .We follow it by a spatial velocity plus temporal domain filtering which provides the high peaks of the R-Peak locations based on this reference points we calculate the rest of the other peaks, their amplitude and onset and offset using time domain windowing technique. We further propose a novel T-wave alternan detection system by using FFT and temporal analysis system. We evaluate our technique using piezonets, normal sinus rhythm as well as T wave alternate public data base. Results shows that our system can detect the peaks with an accuracy of 91.5333% and precision of 0.0546 recall of 1.2582. Keywords— T wave alternan, spatial velocity.
