Cardiac Electrophysiology Clinics, 2017
The ventricular conduction system starts below the His bundle, where it bifurcates into the right and left bundle branches that taper out to the subendocardial Purkinje network, which activates the ventricular myocardium. This system is responsible for the synchronized and almost simultaneous activation of both ventricles.

Supraventricular Arrhythmia With Abnormal QRS Complex
Archives of Internal Medicine, 1972Thus far, the discussion of supraventricular arrhythmia with abnormal QRS complex has included preexisting conduction defects, the preexcitation syndrome (Wolff-Parkinson-White syndrome), and functional bundle-branch block due to sudden shortening of cycle length, often combined with prolongation of preceding cycle; the latter is popularly called the ...

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 [PDF]
AACN Advanced Critical Care, 1992 Electrocardiographic monitoring for dysrhythmias is a major responsibility of critical care nurses, and patients with wide QRS complex tachycardias present a challenge. Criteria for differentiating the impulse origin as ventricular or supraventricular are well documented: QRS duration, QRS morphology, QRS axis, and presence of atrioventricular ...

THE QRS COMPLEX OF THE ELECTROCARDIOGRAM
Archives of Internal Medicine, 1943The electrocardiogram is a photographic record of the differences in electrical potential existing between two points on the body surface at every instant during the time the record is being taken. On the ordinates of the record one reads the potential differences; on the abscissas the time is given.

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.

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 ...
