Patient Examination

Many patients are routinely referred to cardiologists from other doctors to confirm that a patient suffers from a cardio-vascular condition or would desire to know the best procedure to treat a patient. A cardiologist is also consulted in a hospital setting in case of patients who have heart failure, heart attack or serious arrhythmia. Since they are very rarely the first doctor consulted by a patient, it is up to the cardiologist to examine the medical history of the patient and ask relevant questions with regard to symptoms.

Recommending and Evaluating Tests

In most cases, a cardiologist is required to prescribe tests in order to do a diagnosis and make a decision regarding best options for treatment.  A cardiologist may order a patient to undergo an Echo Cardio Gram (ECG), a test which studies the picture of structure and functioning of heart of a patient. Another test is a stress test which measures the performance of the heart during physical activity. X-rays and blood tests will also help the cardiologist with diagnosis and treatment plan. Another procedure done by some cardiologists is cardiac catheterization which involves keeping a tiny  tube in or near the heart for ascertaining  electrical impulses, click pictures or aid in clearing a blockage. After completion of tests, the cardiologist will make a study and construe the results.

Tests ordered by a cardiologist include:

  • ECG
  • Ambulatory ECG
  • Exercise test
  • Cardiac catheterization

Patient Treatment

After a cardiologist detects what is amiss in the patient, there is a need to decide about the best options for treatment. For instance, he may have to do referring of the patient to a cardiac surgeon to conduct surgery to correct abnormalities in the heart like a procedure for valve replacement.  Also, he may even make the recommendation that the best treatment for a patient is via medication. In some cases, a patient may need a lifestyle change and cardiologist may advise patients about how to implement the needed changes. A cardiologist may also see a patient for care in follow-up like conducting regular exams after a case of heart attack. He might serve as a member of the medical team of the patient, working along with other medical professionals and physicians for optimizing the health of the patient.

Conducting Invasive Procedures

A cardiologist happens to be different from a cardiac surgeon. But some cardiologists conduct invasive procedures on a limited basis like cardiac catheterization, implanting of defibrillator and insertion of pacemaker.


Cardiologists have extensive training needs. This consists of 4 and a half years of medical school, and 1 year of internship, 2 years of MD  (post graduation in general medicine )/ 3 years of DNB ( Respiratory Medicine) and 3 years of DM, Cardiology ( fellowship doctorate).
