It is noticed that the QRS complex has the largest slope in a cardiac cycle; derivative process would result in effective detection of QRS region. The algorithm starts with three-point first derivative of the signal x(n) as (2)y0n=xn−xn−2 Followed by the second derivative as (3)...

The QRS complex was measured as the interval between the initial QRS depolarization and the J point. Value of the New Spline QTc Formula in Adjusting for Pacing-Induced Changes in Heart Rate The analysis of the different cardiac waves in the ECG signals is of major importance; the P wave re...
Again, the spread takes place outside of the conduction system which is slow and causes widening of the QRS complex. Aberrant ventricular conduction (aberrancy): Aberrant conduction is actually a bundle branch block that occurs when the length of the cardiac cycle is rapidly changed, particularly ...
Referring to the ECG,the QRS complex represents ventricular A) contraction. B) repolarization. C) relaxation. D) depolarization. What ion is responsible for depolarization in a cardiac myocyte? What is the cardiac cycle in the heart? Fill in the blank: The component of the normal E...
Visible fragmentation of the QRS complex has repeatedly been described as an indicator of increased risk of adverse cardiac events46,47,48,49. It has also been observed that fragmented QRS complex is more often present in males compared to females50and that, in cardiac patients, QRS abnormalities...
The aggregate RV and LV depolarization wave and the subsequent T-wave accompanying repolarization of the depolarized myocardium are referred to as the QRST portion of the PQRST cardiac cycle complex when sensed across external ECG electrodes and displayed. When the amplitude of the QRS ventricular ...
