Real-time Heart Monitoring and ECG Signal Processing

چکیده
Arrhythmias are a form of heart disease involving irregular heartbeats. Premature ventricular contractions (PVCs) are a type of arrhythmia that may indicate ventricular tachycardia (VT), a potentially life-threatening condition. A stand-alone embedded system has been developed to facilitate real-time arrhythmia detection, performing electrocardiogram (ECG) signal processing and alerting the patients doctor of VT via wireless messaging. Heart data records from the MIT-BIH arrhythmia database were used to test the accuracy of the template-matching algorithm. For testing, a PC program sent heart data to the CC3200 LaunchPad using the WFDB toolbox (which accesses the arrhythmia database). For our template-matching algorithm, the preliminary MATLAB simulation results have an overall accuracy of 91% and a PVC sensitivity of 85.9% for the 18 records tested. These results suggest that the template-matching algorithm is a viable, low-complexity solution for PVC detection.

The aim of this study is to show that the measures derived from Electrocardiogram (ECG) signals many a time perform better than the same measures obtained from heart rate (HR) signals. A comparison was made to investigate how far the nonlinear symbolic dynamics approach helps to characterize the nonlinear properties of ECG signals and HR signals, and thereby discriminate between normal and cong...
