WebbThis phenomenon is known as T-wave memory. It was originally observed in 1969 by Chatterjee et al, when after cessation of ventricular pacing during sinus rhythm with normal ventricular activation, negative T waves were present in the leads, showing a negative QRS during ventricular pacing. Webb26 juli 2016 · ABNORMALITIES OF THE QRS COMPLEX. The normal QRS complex has four characteristics: 1. Its duration is no greater than 120 ms (three small squares). 2. In a right ventricular lead (Vj), the S wave is greater than the R wave. 3. In a left ventricular lead (V 5 or V 6 ), the height of the R wave is less than 25 mm. 4. Webb11. T Wave Abnormalities Introduction. The T wave is the most labile wave in the ECG. T wave changes including low-amplitude T waves and abnormally inverted T waves may be the result of many cardiac and non-cardiac conditions. The normal T wave is usually in the same direction as the QRS except in the right precordial leads (see V2 below). sql nom colonne

WebbSinus arrhythmia is a kind of arrhythmia (abnormal heart rhythm). For the most common type of sinus arrhythmia, the time between heartbeats can be slightly shorter or longer depending on whether you’re breathing in or out. Your heart rate increases when you breathe in and slows down when you breathe out.
