Final answer:

The likely cause of the woman's symptoms is pulmonary embolism.

Explanation:

The likely cause of the woman's symptoms based on the information provided is Pulmonary embolism.

The symptoms of progressive fatigue, shortness of breath, chest discomfort, and elevated heart rate, along with the presence of mild cardiomegaly on chest radiograph and non-specific ST segment and T wave changes on electrocardiogram, are consistent with a pulmonary embolism.

A pulmonary embolism occurs when a blood clot travels to the lungs and obstructs the pulmonary arteries, leading to reduced blood flow and oxygen delivery to the lungs and other organs.
