A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. This term can be confusing, as not all ECG leads contain all three of these waves ...

The atrial rate is indicated by the frequency of the P waves. The ventricular rate is indicated by the frequency of the QRS complexes. In the absence of disease, the atrial rate should be the same ...

1). What is the mechanism for the progressive widening of QRS complexes and for the normal narrow QRS complexes observed in the 13 and 18 atrial-paced beats? The occurrence of overdrive atrial ...

Conclusion: ECG systems, comprising 2 or 6 leads, can be substituted for the 12-lead ECG for certain clinical and research applications (pertaining to the amplitude of QRS complexes), attesting to ...

QRS will leverage artificial intelligence ... “Combined, these technologies will provide predictive capabilities, analyze the complex web of interdependencies and automate obsolescence management ...
