Abstract: Electrocardiogram (ECG) signal shows the electrical activity of the heart and provides useful information that helps in analyzing the patients heart condition. This paper gives an insight in to the LabVIEW software which helps in the analysis of ECG signals. LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a graphical programming language that uses icons instead of lines of text to create programs. Processing of an ECG signal is done in two stages, filtering & feature extraction. Filtering is done through wavelet transform technique to remove the baseline wandering and noise due to breathing. ECG feature extraction VI is used for extracting various features like P onset, P offset, QRS onset, QRS offset, T onset, T offset, R, P & T wave, with which we calculate various parameters like Heart rate, QRS amplitude and their time duration. Further the heart rate is used to detect tachycardia and bradycardia conditions, while QT mean values are used to diagnose various heart diseases such as atrial tachycardia and hyperkalemia. The obtained result is alerted to the doctor through wireless communication.
