A cardiology visit may include several tests to check how well the heart is working. Common tests include an electrocardiogram (ECG), echocardiogram, blood pressure monitoring, blood tests, and sometimes a chest X-ray. An ECG records the heart’s electrical activity, while an echocardiogram uses sound waves to create images of the heart. The doctor chooses tests based on the patient’s symptoms, age, and medical history. Children may need specialized heart evaluations for symptoms such as fainting, breathing difficulty, or an unusual heartbeat. A pediatric cardiologist in Chennai can assess these concerns and recommend appropriate tests and care based on the child’s needs.
