title: Adaptive fetal ECG signal extraction based on LabVIEW and C# implementation
abstract: This paper deals with the using of adaptive filters in the biological signal processing area. It focuses on the design and implementation of adaptive filters based on virtual instrumentation in the LabVIEW development environment from National Instruments. The experiments are devoted to certain adaptive algorithms (LMS, NLMS, RLS, QR RLS) which are implemented in LabVIEW and C# programming language in the form of dynamically linked DLL libraries. The implemented algorithms are tested in extraction of fetal ECG signal from the abdominal ECG signal of mother. The algorithms are compared in their computation time and the improvement of signal to noise ratio (SNR) value.

title: Pulse Transit Time Based Blood Pressure Estimation in LabVIEW Environment using Non Contact ECG Electrodes and Pulse Sensor
abstract: Sphygmomanometers are conventionally used for measuring blood pressure, namely systolic and diastolic pressures. While measuring the maximum output pressure of the heart, namely systolic, the blood flow is cut with the pressure exerted by the cuff, which may discomfort the patient. To avoid this discomfort, we propose a contactless and cuffless blood pressure measurement system (CBPS) of estimating the blood pressure using non contact capacitively coupled ECG electrodes and a commercial pulse sensor together with an analog signal acquisition circuitry and a LabVIEW program which calculates the systolic and diastolic pressures from the pulse transit time (PTT) Moreover, non contact ECG electrodes do not need conductive gel, and the CBPS provides almost instant BP results. These features of the CBPS enable continuous recording of the blood pressure together with the ECG signals in a holter device utilizing contactless electrodes.

title: A Low Cost Remotely Analysis of ECG Signal based on LabVIEW
abstract: Electrocardiography (ECG) is a popular technique that is widely used to detect cardiac problems. One of the difficulties in developed countries is the lack of the number of specialists in heart diseases compared with the number of patients. Another problem is the high cost of ECG devices and medical services. This work helps to minimises the effects of these problems by development of a low cost ECG that can register and analyse the ECG signal of the patient. The ECG graph and the analysed data are sent to a remote expert for diagnosis by utilising diverse of communication technologies. In this work, the Internet is used as a low price and widely available technology. The history of the patient records is also stored in a cloud server. So the solution is characterized by being cheap, easy to use, and efficient for remote usage.

title: National Instruments LabVIEW Biomedical Toolkit for Measuring Heart Beat Rate and ECG LEAD II Features
abstract: Electrocardiogram (ECG) is undoubtedly the gold method for assessing heart activities. However, the ECG machine for measuring ECG is mostly only available in health care center especially in the third world countries. Therefore, this research proposed to utilize the product of National Instruments i.e. LabVIEW Biomedical Toolkit and data acquisition device as an alternative approach to acquire ECG features and heart beat rate (HBR) As for performances verification, the NI LabVIEW instruments are tested simultaneously with two types of ECG machine which are Philips PageWriter TC 30 and KenZ ECG 108. The results indicated that the ECG features and HBR obtained from NI LABVIEW instruments are agreed well with the measurements attained from both of the ECG machines. Hence, this study proved that NI LabVIEW instruments are highly potent for measuring ECG features and HBR. Moreover, the computerized NI LabVIEW instruments with the self interpretation function can always outperform most of the conventional ECG machines that are still required cardiologists for manually interpreting the results printed on the ECG paper.

The collection and analysis system performance is reliable, and the module is practical and easy to operate. The normalization of collection provides convenience and reference for the analysis and recognition of the follow up heart sound, ECG data building and pathology signal.

title: Development of a 12 Lead ECG Signal Processing Algorithm Using NI LabVIEW(r) and NI ELVIS(r)
abstract: Several research projects about ECG signal processing have been made by proponents from different countries, most of which focused on the portability, accessibility and interpretations presented. The projects implemented algorithms which only eliminated a certain number of ECG noise artifacts. ECG NI, on the other hand, is a research project which aims to create a signal smoothing algorithm using a new technological platform the NI LabVIEW. By using NI LabVIEW and its compatible hardware device, the NI ELVIS, the proponents created a system which eliminates noise artifacts such as Baseline Wander, Wideband Noise and Power Line Interference for a 12 lead ECG reading. The signal processing was done through the use of LabVIEW's virtual instruments (VIs) Aside from eliminating noise, it also provides readings and pre diagnostic interpretations as well as the option to export the waveform for reference. ECG NI was subjected to noise immunity, accuracy and user friendliness tests. Based on the results of these tests, ECG NI is noise immune in terms of the ECG signal read due to its high signal to noise ratio, the accuracy was acceptable since previous studies only focused on certain noise artifacts without verifying the accuracy of the preprocessed signal. The user friendliness of ECG NI was determined through surveying cardiologists. Hence, the proponents were able to create a signal smoothing algorithm using NI LabVIEW and NI ELVIS which was noise immune, accurate and user friendly.

title: A Differential Algorithm for Non Invasive Extraction of Fetal ECG and Analysis using LabVIEW
abstract: In this paper by using Differential techniques, extracting the Fetal ECG for Fetal extraction from two ECG signals recorded at thoracic abdominal area of mother's skin. The thoracic ECG is assume to be almost completely maternal ECG while abdominal ECG is consider to be composite as it contains both mother's and Fetal ECG signals. The maternal component in abdominal ECG is non linearly transform version of maternal ECG,so by identifying this non linear relationship and aligned maternal ECG signals with maternal component in abdominal ECG. Thus we extract the Fetal ECG component by subtracting the aligned version of maternal ECG signals from the abdominal ECG. Extracted ECG will study along with continuous comparison with sonographic report. The User interface will be based upon LabVIEW. The output is connected to the personal computer (pc) for analysis of the result which is

title: Parameter Extraction of ECG Using Labview
abstract: The electrocardiogram presents the electrical activity of the heart, which informs about the condition of the heart muscle. The interpretation and diagnostic of this signal lead to detect various cardiac abnormalities and diseases, for that the feature extraction and the denoising are very useful in cardiology. Therefore, nowadays the interest of medical researchers is to invent techniques according to the technological revolution for the ECG diagnostic instead of the traditional ones that are until now still used at hospitals and clinics. The purpose of this project is to develop an algorithm based on efficient approaches and methods via the Labview Software interface, in order to extract and calculate the main parameters from an ECG signal. The recorded ECG signals were taken from the MIT BIH Arrhythmia database and tested by our algorithm. The main features that were extracted are P, Q, R, S and T amplitudes and durations, all waves onsets and offsets, PR, ST and QT segments and PR, QT interval and QRS duration. In order to evaluate the performance and efficiency of our VI code, we compared the extracted feature values to the real one read manually from the ECG paper and we concluded that it achieved good results especially in detecting all waves' amplitudes, QRS duration, PR and QT intervals.
