What Tests Are Conducted By Cardiologists?

Cardiologists are specialized healthcare professionals trained to diagnose, treat, and manage a wide range of cardiovascular conditions. To accurately assess heart health and determine the presence of any abnormalities or diseases, the best cardiologist in Dubai utilizes a variety of diagnostic tests and procedures. These tests are instrumental in evaluating cardiac function, identifying risk factors, and guiding treatment decisions for patients with cardiovascular concerns.

Electrocardiogram (ECG or EKG):

An electrocardiogram is a non-invasive test that measures the electrical activity of the heart. It records the heart’s rhythm and can detect abnormalities such as arrhythmias, conduction disorders, ischemia, and signs of previous heart attacks. ECGs are commonly performed during routine check-ups, as well as in patients experiencing symptoms such as chest pain, palpitations, or shortness of breath.

Echocardiogram:

An echocardiogram is a diagnostic imaging test that uses sound waves (ultrasound) to create images of the heart’s structure and function. It provides detailed information about the heart’s chambers, valves, and blood flow patterns, allowing cardiologists to assess cardiac function, identify structural abnormalities, and evaluate for conditions such as heart failure, valve disorders, and congenital heart defects.

Stress test:

A stress test, also known as an exercise tolerance test or treadmill test, assesses how well the heart performs under physical stress. Patients typically walk or jog on a treadmill while their heart rate, blood pressure, and ECG are monitored. Stress tests are used to evaluate for coronary artery disease, assess exercise capacity, and identify abnormal heart rhythms or symptoms such as chest pain or shortness of breath during exertion.

Cardiac catheterization (Angiography):

Cardiac catheterization is an invasive procedure used to evaluate the coronary arteries and heart chambers. A catheter is inserted into a blood vessel and guided to the heart, where contrast dye is injected to visualize blood flow and detect blockages or narrowing in the coronary arteries. Cardiac catheterization is performed to diagnose coronary artery disease, assess heart function, and guide treatment interventions such as angioplasty or stent placement.

Holter monitor:

A Holter monitor is a portable device worn by patients to continuously record the heart’s electrical activity over a 24- to 48-hour period. It is used to evaluate for arrhythmias, palpitations, and other cardiac abnormalities that may occur intermittently or during daily activities. Holter monitoring provides valuable insights into the heart’s rhythm and helps cardiologists diagnose and manage rhythm disorders.
