However, early activation of the His bundle can also occur in high septal ventricular tachycardia (VT), resulting in relatively narrow QRS complexes of 110 –140

Although rarely life-threatening, these arrhythmias are a common source of morbidity. QRS complex corresponds to the depolarization of the right and left ventricles. Duration of the complex may be calculated simply by means of an electrocardiogram, an easy, economical, and noninvasive investigation that is usually readily available in an outpatient setting. 2016-03-04 Ventricular rhythms have a wide QRS complex (>120 ms). Possible causes should be investigated and treated immediately, with particular attention to the …. ›.
QRS complex a group of waves seen on an electrocardiogram, representing ventricular depolarization. Called also QRS wave . It actually consists of three distinct waves created by the passage of the cardiac electrical impulse through the ventricles and occurs at the beginning of each ventricular contraction. Formation of QRS complex in lead III Similar to the QRS complex in all limb leads, we can understand QRS complex in all six chest leads when the vectors in QRS vector loop are projected on chest lead axes (Fig. 4.6).

Although its origins lie in psychology and personal construct theory, it's also used as a measurement of task difficulty in other fields.

Wide QRS complex tachycardia (WCT), defined as heart rate (HR) >100 beats per minute (bpm) with a QRS duration >120 ms, is a common arrhythmia with potentially life-threatening consequences, making rapid and accurate diagnosis with initiation of appropriate therapy essential.

Although such tachycardias often occur in patients with a normal heart and seldom represent life-threatening conditions, they may cause bothersome symptoms.
It actually consists of three distinct waves created by the passage of the cardiac electrical impulse through the ventricles and occurs at the beginning of each ventricular contraction. Konkordans av QRS-komplex från V1-V6 (d v s alla positiva eller alla negativa) talar starkt för VT. Tid från start av QRS till botten av S-våg >100 ms i prekordiala avledningar talar för VT. Kombinationen av ett mono- eller bifasiskt ”högergrenblocksliknande” QRS-komplex och en negativ R/S-kvot i V5 är diagnostiskt för VT.
The QRS width is useful in determining the origin of each QRS complex (e.g.

Background: Patients with acute coronary occlusion (ACO) may not only have ischemia‐related ST‐segment changes but also changes in the QRS complex.

Bereksi-Reguig, Göran Salerud (2017) STRONG REAL-TIME QRS COMPLEX DETECTION Journal of Mechanics in Medicine and Biology For electrocardiography, we examine how and why the Hilbert transform can be used for QRS complex detection. Also, what are the advantages and limitations av J Timisjärvi · 1982 — The P wave was positive in leads II, III and aVF, negative in lead aVL and The most common forms of QRS complex were R and rS in leads I and aVR; R, A form of ventricular pre-excitation characterized by a short PR interval and a normal QRS complex.

La présence d'une tachycardie irrégulière à QRS larges The aim of the present work is to detect the QRS wave from electrocardiogram ( ECG) signals. Initially the baseline drift has been removed from the signal followed 10 Oct 2013 Background Cardiac-resynchronization therapy (CRT) reduces morbidity and mortality in chronic systolic heart failure with a wide QRS complex The QRS complex is a vital wave in any ECG beat.
