How does a Cardiologist check your Heart Health?

Blood Tests – Help determine the level of cholesterol, sodium, potassium etc in the blood and determine if there are signs of heart problems or failure. 

Electrocardiogram or ECG – It is a procedure in which electrodes are attached to the skin to read the heart’s activity. It looks into electrical activity and heart rhythm to quickly detect heart problems.

Angiogram – Helps detect if there are any restrictions or blockages in the blood that is pumped to your heart. It is a type of cardiac catheterization procedure. 

Echocardiogram – Echocardiogram or echo helps determine structural abnormalities in the heart and surrounding areas. It can also help determine if there are any infections in the valves. This test looks at the output or how much blood the heart is pumping at a given time.

Stress Test – The exercise tolerance test helps determine whether there is enough blood supply to your heart through the course of the exercise. Lack of adequate blood supply to the heart during the exercise may reflect signs of issues in heart health. It monitors heart rate, tiredness, blood pressure and so on. 

Transesophageal Echocardiography – Uses ultrasound or high frequency waves to obtain a clear picture of one’s heart and valves. This can help assess if there are blood clots in the heart, functioning of heart valves. It can also help detect heart valve diseases. In this procedure, a very thin tube is used which is inserted through the mouth and reaches the top chambers of the heart for the screening.
