QRS Complex (When ventricles contract), and T wave (When ventricles relax). The P wave is followed by a short delay known as the atrioventricular (AV) node, which shows electrical depolarization. This node is shown in the form of a straight horizontal line on ECG paper, called PR interval...

Total electromechanical systolic interval (QS2) was measured from the onset of the QRS complex on the ECG to the first high-frequency vibrations of the aortic component of the second heart sound on the phonocardiogram. The bPEP was also automatically calculated by subtracting the bET from the ...
Fragmented QRS (fQRS) is a convenient marker of myocardial scar evaluated by 12-lead electrocardiogram (ECG) recording. fQRS is defined as additional spikes within the QRS complex. In patients with CAD, fQRS was associated with myocardial scar detected by single photon emission tomography and was...

In ventricular preexcitation, ST-T changes are directed opposite to the delta wave of the QRS complex. The magnitude of the ST-T change is dependent on the magnitude of the QRS-waveform changes when the excitation pathways change. The secondary ST- and T-wave changes associated with ...
In particular, such arrhythmias are associated with heart failure, left ventricular hypertrophy (characterized by an abnormal QRS complex), myocardial ischemia, and myocardial infarction (both in the acute phase and after remodeling). The coadministration of magnesium should be considered to facilitate ...
Since the wave shape, frequency, pulse width, and rise-fall time of the magnetic field matches the QRS Complex of the human heart rate when the square wave impulses are transmitted through the chest wall but at a higher Fourier Bessel function of the muscle contraction frequency of the system...
