The Electrocardiogram Classification Research on Electrocardiogram RR Interval Variation

QRS complex wave segment of electrocardiogram (ECG) beat reflects the electrical activity of the heart. The RR interval is always be used in the arrhythmia classification. In this paper, we use statistical histogram method to analysis RR interval features in depth. From all of RR interval statistical result, RR interval is a very important and basic ECG beat classification feature. However merely considering RR interval, there is no obvious classification boundary between premature ventricular contract (PVC) and normal beat, other features should be introduced.
