Small wave after qrs
Naming of the waves in the QRS complex is easy but frequently misunderstood. The following rules apply when naming the waves: 1. A deflection is only referred to as a waveif it passes the baseline. 2. If the first wave is negative then it is referred to as Q-wave. If the first wave is not negative, then the QRS complex does … See more The QRS complex can be classified as net positive or net negative, referring to its net direction. The QRS complex is net positive if the sum of the positive areas (above baseline) exceeds that of the negative areas (below … See more Depolarization of the ventricles generate three large vectors, which explains why the QRS complex is composed of three waves. It is fundamental to … See more A QRS complex with large amplitudes may be explained by ventricular hypertrophy or enlargement (or a combination of both). The electrical currents generated by the ventricular … See more Prolongation of QRS duration implies that ventricular depolarization is slower than normal. The QRS duration is generally <0,10 seconds but must be <0,12 seconds. If QRS duration is ≥ 0,12 seconds (120 milliseconds) then the … See more WebLong QT syndrome is the prototypical disorder of ventricular repolarization (VR), and a genotype-phenotype relation is postulated. Furthermore, although increased VR heterogeneity (dispersion) may be important in the arrhythmogenicity in long QT syndrome, this hypothesis has not been evaluated in humans and cannot be tested by conventional …
