You should consult a cardiologist for symptoms such as chest discomfort, shortness of breath, palpitations, dizziness, unusual fatigue, or swelling, especially if symptoms are persistent or recurrent. People with risk factors such as high blood pressure, diabetes, high cholesterol, smoking, or a family history of heart disease may also benefit from cardiovascular evaluation.

Cardiologists evaluate and manage a range of cardiovascular conditions, including hypertension, coronary artery disease, heart rhythm disorders, heart failure, valve-related conditions, and other heart and blood-vessel problems.

Depending on the symptoms and clinical assessment, tests may include an ECG, echocardiography, blood tests, cardiac monitoring, or other investigations recommended by the cardiologist.

An electrocardiogram (ECG) records the electrical activity of the heart and can help assess heart rate and rhythm and identify certain cardiac abnormalities. A cardiologist may recommend an ECG based on the patient's symptoms and clinical needs.
