QRS Complex Detection and Analysis of Cardiovascular Abnormalities: A Review

Abstract

The ability to evaluate various Electrocardiogram (ECG) waveforms is an important skill for many health care professionals including nurses, doctors, and medical assistants. The QRS complex is a vital wave in any ECG beat. It corresponds to the depolarization of ventricles. The duration, the amplitude and the complex QRS morphology are used for the purpose of cardiac arrhythmias diagnosis, conduction abnormalities, ventricular hypertrophy, myocardial infarction, electrolyte derangements etc. In this review, the different algorithms and methods for QRS complex detection have been discussed. Moreover, this review conceptualizes the challenge by discussing the effect of QRS complex on various critical cardiovascular conditions.
