Is p mitral also present in right atrium enlargement?

“P-mitrale” (P mitrale) is a term used to describe a specific pattern of the P wave on an electrocardiogram (ECG) that is associated with left atrial enlargement. It is characterized by a broadened and notched P wave with a bifid (double-peaked) or M-shaped appearance.

Left atrial enlargement (LAE) typically leads to changes in the P wave morphology, resulting in the P mitrale pattern. These changes occur due to altered electrical conduction and depolarization of the left atrium.

In contrast, “P-pulmonale” (P pulmonale) refers to changes in the P wave morphology associated with right atrial enlargement (RAE). It is characterized by an increased amplitude and a peaked or taller P wave in leads II, III, and aVF.

If a person has right atrial enlargement (RAE), the P wave changes (P pulmonale) will be more prominent in leads II, III, and aVF. The P wave in lead V1 may also show changes, typically a more prominent negative deflection due to the right atrium being closer to this lead.

In summary:

  • “P mitrale” is associated with left atrial enlargement and leads to a broadened, notched P wave with a bifid or M-shaped appearance.
  • “P pulmonale” is associated with right atrial enlargement and leads to a tall and peaked P wave, especially in leads II, III, and aVF.

Both P mitrale and P pulmonale are ECG findings that can provide valuable information about the state and size of the atria, which may be indicative of various cardiac conditions.
