This article presents the result of applying a fuzzy neural network to QRS wave recognition in Electrocardiogram (ECG) signals. Feature extraction is performed on records of the MIT-BIH Arrhythmia Database to obtain input values for the fuzzy neural system. The features or primitives are based on...

1. Understand the ECG Phases: The ECG (electrocardiogram) consists of several phases: P wave, QRS complex, and T wave. Each of these phases corresponds to specific electrical events in the heart. 2. Identify the Cardiac Events: - P Wave: Represents atrial depolarization (contraction of the ...
