Question

ECG with tall peaked/biphasic P wave means:

A. Enlarged right atria, "pulmonale," commonly seen in individuals with chronic pulmonary diseases.
B. Enlarged left atria, indicative of left-sided heart failure or mitral valve disease.
C. Atrial fibrillation, characterized by irregularly shaped P waves due to erratic atrial contractions.
D. Atrial flutter, presenting as rapid and regular atrial depolarizations, resulting in a "sawtooth" pattern.

Answer 1

An ECG with tall peaked or biphasic P waves indicates enlarged right atria, or "pulmonale," often observed in chronic pulmonary diseases, matching option A in the provided choices.

Step-by-step explanation:

An ECG with tall peaked or biphasic P waves is indicative of enlarged right atria, commonly referred to as "pulmonale," and is often seen in individuals with chronic pulmonary diseases. This description matches option A from the choices provided. The P wave on the ECG represents the depolarization and contraction of the atria. When the right atrium is enlarged, as may happen in response to chronic lung diseases that increase the resistance the right side of the heart has to pump against, the P wave can become peaked. This is different from changes seen in atrial fibrillation, atrial flutter, or enlargement of the left atria.
