Key result
A novel automatic classification algorithm for premature ventricular contraction based on a three-bit linear interpolation error signal achieved a sensitivity of 94.8% and a specificity of 98.6%.
Why the study?
Early and effective ECG diagnosis could help prevent deaths from sudden cardiac arrest, prompting the development of new methods for automatic premature ventricular contraction classification.
A novel three-bit linear interpolation error signal-based algorithm demonstrates high sensitivity and specificity for automatic PVC detection in standard ECG databases.
About three million people die from sudden cardiac arrest (SCA) or infarction each year. It is the biggest killer on the planet and it can happen to anyone, anywhere, and anytime. Early and effective diagnosis from ECG signals can help save a large part of these SCAs. Premature ventricular contraction (PVC) detection and classification was performed with different methods. A new method of automatic classification of PVC based on a three‐bit linear interpolation error signal (LIES) is proposed in this paper. We start by a QRS detection, a nonlinear transformation and then a sliding window. This method was tested on normal and abnormal beats obtained from MIT‐BIH and AHA databases. The proposed algorithm with a sensitivity 94.8% and a specificity was 98.6%. is accurate. This algorithm is also automatic, robust, and fast.
