A Digital Filter for the QRS Complex Detection
IEEE Transactions on Biomedical Engineering, 1979The five step digital filter has been developed which removes components other than those of QRS complex from the recorded electrocardiogram (ECG). The final step of the filter produces a square wave whose on-intervals correspond to the segments with QRS complexes in the original wave.

It is proposed to model the derivative of electrocardiogram (ECG) signal, which we refer to as dECG, instead of the ECG signal. It is shown that the QRS complex in the dECG signal can be represented in the frequency domain by an all-pole model of appropriate order, the coefficients of the model being determined using the covariance method of linear ...

Wide QRS complex tachycardia is a common clinical occurrence and presents a diagnostic challenge for the physician. History, physical examination, chest radiographs, and electrocardiographic analysis are important in making the correct diagnosis. Diagnosis of ventricular tachycardia is supported by history of prior myocardial infarction or congestive ...

Narrow QRS Complex Tachycardias
Mayo Clinic Proceedings, 1995Regular narrow QRS complex tachycardias are a common problem encountered by general internists or family practitioners. Although such tachycardias often occur in patients with a normal heart and seldom represent life-threatening conditions, they may cause bothersome symptoms.

In a man with a wide-QRS complex tachycardia, a history of an inferior left ventricular scar, atrioventricular dissociation during the tachycardia, and a QRS morphology inconsistent with right or left bundle branch block exclude a diagnosis of supraventricular tachycardia with aberrant ventricular conduction due to bundle branch block or ventricular ...

QRS complex based human identification
2015 IEEE International Conference on Signal and Image Processing Applications (ICSIPA), 2015In the last years, the electrocardiogram signal has become an important biometric modality due essentially to the physiological or/and behavioral characteristics variation of the heart among different individuals. The aim of this paper is to present a human identification approach using some time and frequency features of the QRS complex of the ECG ...
