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; yet a “QRS complex” is said to be present regardless. For example, the normal QRS complex in ...
The QRS complex is widened, giving the superficial appearance of a bundle branch block pattern. However, the wide QRS is caused not by a delay in ventricular depolarization but by early stimulation of the ventricles. The T wave is also usually opposite in polarity to the wide QRS in any lea...

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....
A central feature of the electrocardiogram (ECG) is the QRS complex, reflecting ventricular depolarization. Abnormalities in the duration and amplitudes of the QRS complex are indicative of (early) cardiac pathology, including disorders of the conduction system and cardiac hypertrophy1,2,3. Abnormal ...
The Sensitivity (Se) and the Specificity (Sp) for QRS complex is found to be 99.59% and 99.53%, whereas for T wave it is of 99.50% and 99.44% respectively. Application/Scope: This algorithm could be implemented in real-time ECG analyzer for possible detection of ventricular chronic heart ...
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
