Cardiology is the branch of medical science which deals with the diseases of the heart and also the circulatory system. Physicians who specialized in this field are called as a cardiologist. Physicians who specialize in cardiac surgery are known as cardiothoracic surgeons or cardiac surgeons.

-The system includes treatment of congenital heart disease, coronary heart disease, valvular heart disease, heart failure, and electrophysiology.

-Diagnostic testing for heart diseases includes Electro-cardiography (ECG), Radiography, Echocardiography, Carotid ultrasound, and Lab tests.

-Tests used to check blocked arteries are Exercise treadmill test and stress echo.


Treatments in Cardiology:

  • Coronary angiography/ Heart catheterization

It is used to know the extent of blockage in the arteries. Catheterization provides information about the blood supply to the heart.


  • Angioplasty/ Stent:

It is to reopen the blocked arteries.

  • Pacemaker implantation:

A pacemaker is inserted to correct slow, irregular or abnormal heartbeats.


  • Cardiac defibrillator implantation:

A small device is implanted under the skin and connected to the heart to monitor the heart rate.

  • Cardiac resynchronization therapy:

A specialized pacemaker is used to re-coordinate the action of the left and right ventricles.

  • Cardiac rehabilitation:

This is to help the heart patient to adopt a healthier lifestyle. It may be recommended for up to 12 weeks.
