The symptoms of cardiomegaly include edema, breath shortness and arrhythmia, which is a condition in which the heart beats excessively slowly or quickly, according to Mayo Clinic. Not all people with cardiomegaly experience symptoms.
It is advisable to seek immediate medical attention when the symptoms of cardiomegaly appear, to receive early diagnosis and treatment, notes Mayo Clinic. Early treatment helps to prevent possible complications, such as death, cardiac arrest, heart failure and blood clots. To diagnose cardiomegaly, a doctor first performs a physical exam on the patient's body before ordering further tests, such as electrocardiogram, blood tests and echocardiogram, to determine the underlying cause. Depending on the underlying condition, treatment options for cardiomegaly may include medications, such as beta blockers, diuretics and anticoagulants, and surgeries, such as coronary bypass surgery, heart valve surgery and heart transplant.
Cardiomegaly is a condition in which the heart is larger than normal due to an underlying condition, which results in a damage to the cardiac muscle or triggers the heart to pump abnormally harder, states Mayo Clinic.

Hemochromatosis, which is a condition in which the level of iron in body is higher than normal, heart valve disease, hypothyroidism and hyperthyroidism are other possible causes of cardiomegaly.
