What is cardiology, and what to expect?

You might be thinking about what is cardiology? Well, Cardiology is concerned with the examination and treatment of disorders of the heart and blood vessels. Someone who has been diagnosed with heart or cardiovascular disease may be referred to a cardiologist for further evaluation.

Cardiology is a specialisation of internal medicine, which means it deals with the heart. An interventional cardiologist and a cardiac surgeon are two completely different professions. Cardiac surgery is performed by a cardiac surgeon who enters the chest cavity. A cardiologist is a medical specialist who specialises in the diagnosis and treatment of cardiovascular disease. In certain cases, the cardiologist may undertake procedures such as cardiac catheterizations, angioplasty, or the implantation of an implanted pacemaker on the patient.

The heart and blood vessels may both be damaged by cardiovascular disease, which is the more serious of the two conditions. In order to become a cardiologist in the United States, one must complete four years of medical school, three years of internal medicine studies, and at least three years of cardiology specialism before graduating.

What are the responsibilities of a cardiologist?

During a physical examination, a cardiologist will assess the patient’s medical history. They may do many exams, including weighing the subject checking the heart, lungs, and blood arteries, among other things.

Interventional cardiologists perform all kinds of heart surgeries, including angioplasties and heart valve replacements. These include stenting treatments, congenital heart defect repairs, and coronary thrombectomy.


They may also perform or order the following tests:

  • It’s possible to see the condition of the heart with cath lab equipment. The heart’s electrical activity is recorded using an electrocardiogram (also known as an EKG or ECG).
  • An ambulatory electrocardiogram (ECG) captures the heart’s rhythms while the patient goes about their daily routine. Small metal electrodes are attached to the chest and connected to a Holter monitor to record heartbeats.
  • Exertion testing, often known as a stress test, measures the heart’s rhythmic variability at rest and during activity. It assesses the heart’s ability and limits.
  • An echocardiogram offers an ultrasound image of the heart chambers and surrounding regions and an indication of how effectively the heart is pumping blood throughout the body.
  • The cardiac output, which may be measured through echocardiography, measures how effectively the heart pumps blood. Pericarditis, an inflammation of the heart’s pericardium, may be detected by this test. Affected cardiac valves might be examined to see any structural issues or infections.
  • Cardiac catheterization involves inserting a catheter into or near the heart. It can take photographs and test the heart’s and electrical system’s functionality. Congenital heart, valve, and coronary artery disorders may be treated using catheter-based procedures and fluoroscopy.

Cardiology focuses on the health of the heart and circulatory system.

Cardiologists are doctors who specialise in the diagnosis and treatment of heart disease.

Several symptoms might suggest cardiac disease.


  • a feeling of exhaustion
  • dizziness
  • discomfort in the chest
  • irregularities in the beating of the heart
  • blood pressure that is out of whack

Many of their patients have had a heart attack, heart failure, or some other kind of cardiac disease. They assist in making choices concerning cardiac surgery, heart catheterization, angioplasty, and stenting.
