Left atrial enlargement is sometimes referred to as:

Left atrial enlargement is often referred to as "P mitrale" due to its characteristic changes on an electrocardiogram (ECG). This term describes specific atrial conduction delays that result from the enlargement of the left atrium, primarily seen in conditions such as hypertension and valvular heart diseases. The presence of P mitrale is indicated by a broad and notched P wave in lead II of the ECG, which reflects the prolonged depolarization time of the enlarged left atrium.

This phenomenon is important to recognize in the clinical setting because it can be associated with an increased risk of atrial fibrillation and other complications. Understanding the significance of P mitrale helps in the assessment of a patient's cardiac condition and guides appropriate management strategies.
