The QRS complex of the ECG represents the depolarization of the ventricles, which leads to the contraction of the heart muscle. Specifically, this electrical signal triggers the ventricles to contract and pump blood out into the arteries. Thus, right after the QRS complex, blood is ejected from the ventricles, ensuring vital circulation throughout the body. Interestingly, the timing of these events is critical for maintaining efficient heart function. If there's a delay or blockage in the conduction system, it can lead to arrhythmias or other cardiac issues. This is why healthcare providers closely monitor the ECG, as it gives us vital clues about heart health and rhythm!
