Web26 de jul. de 2024 · No P Wave on ECG. No P wave on an ECG does not mean the heart has stopped beating – the QRS complex and T wave follow to show the ventricles are still working. It is possible that the P wave is just extremely irregular and not obvious, such as in atrial fibrillation. WebThe QRS complex (ventricular complex): normal and abnormal configurations and intervals. A complete QRS complex consists of a Q-, R- and S-wave. However, all three waves may not be visible and there is always variation between the leads. Some leads may display all waves, whereas others might only display one of the waves. WebWarren Smith, Margaret Hood, in Cardiothoracic Critical Care, 2007. Accelerated Junctional Rhythm.
