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. WebWhen a P wave was present, RP/PR interval ratio > 1 was more common in atrial tachycardia (90%). By multivariate analysis, presence of a P wave separate from the QRS complex, pseudo r' deflection in lead V(1), QRS alternans, preexcitation during sinus rhythm, ST-segment depression > 2 mm or T-wave inversion, or both, were independent …
