Extra p wave
WebFeb 1, 2024 · When P waves are not followed by the QRS complex, the ventricles fail to contract, and this leads to reduced mean arterial pressure (MAP) that can cause dizziness and fainting (due to the drop in cerebral blood pressure). When the ECG trace displays an occasional extra P-wave, where, otherwise, impulses still travel through the AV node , … WebThe P wave is normally less than 0.11 msec (just under three small boxes). The long or abnormally shaped P wave occurs because of delay in electrical activation of the enlarged left atrium, as electricity moves leftward from the SA node. A P wave longer than 0.11 milliseconds is diagnostic of left atrial enlargement (LAE).
