Biphasic p wave atrial enlargement
WebThe P wave represents atrial depolarization. It is upright in most leads except aVR. It may be biphasic in leads II and V1; the initial component represents right atrial activity, and the 2nd component represents left atrial activity. ... III, and aVF (P pulmonale); left atrial enlargement produces a P wave that is broad and double-peaked in ... WebRight atrial enlargement (hypertrophy) leads to stronger electrical currents and thus enhancement of the contribution of the right atrium to the P-wave. The P-wave will display higher amplitude in lead II and lead V1. ... The P …
