The analysis of the different cardiac waves in the ECG signals is of major importance; the P wave represents the depolarization wave that spreads from the sinoatrial node throughout the atria; the QRS complex represents ventricular depolarization, while the T wave represents ventricular repolarization....
The paper at hand presents a framework for the monitoring of the QRS complex of an electrocardiogram. Such a complex is made up of three waves Q, R and S and carries the most important information in an ECG because it influences the ventricular contraction and relaxation of the heart. This...

For instance, the QRS complex of the ECG reflects the electrical activity within the heart during the ventricular contraction, and it often has a long duration (>120ms) in heart failure patients. It is possible to obtain much information that is helpful for diagnosing different types of ...

The P-wave represents the depolarisation of the atria, which leads to atrial contraction. The QRS complex represents the depolarisation of the ventricles, which initiates the ventricular contraction. The T-wave represents the return of the ventricles from excited to normal state (repolarisation...
To solve the question of which ECG phase correctly pairs with the cardiac event responsible, we can follow these steps:1. Understand the ECG Phases: The ECG (electrocardiogram) consists of several phases: P wave, QRS complex, a
The QRS-complex of the ECG is generated by the depolarization of the AV-node and ventricular myocardium. A. True B. False 3. The T-wave of the ECG occurs The QRS wave of the ECG represents a) atrial contraction. b) atrial relaxation. c) the firing ...
