Cardiology Jobs

Provides information on Cardiology jobs including duties and tasks, educational requirements and specializations.

Smoking, obesity, high cholesterol, diabetes, and other factors make people susceptible to heart disease. In fact, it is the leading cause of death in several countries across the globe. There are also other conditions, such as birth defects, injury, and complications from other illnesses or medical procedures that cause cardiac problems. Our heart is one of the most important organs in our bodies, and when it isn’t working correctly, we want a skilled, experienced health care professional to help us address the problems. A career in cardiology can be a challenging and rewarding experience.

What is Cardiology?

Cardiology is an internal medicine subspecialty that focuses on the diagnosis and treatment of health problems related to the heart, arteries and veins that comprise the cardiovascular system. Cardiologists work in clinics and hospitals where they assess and treat patients. They may work with patients who have diseases or conditions such as hypertension, pulmonary embolisms, congenital heart disease, arrhythmias, and vascular disease. They may provide emergency care for those suffering heart attacks. And they are also involved when patients undergo hearty surgery or cardiac transplants.

Duties & Tasks

Daily duties and tasks for a cardiologist include:

  • Assessing patients and recommending treatment plans
  • Reading and completing medical records
  • Treating patients in an emergency setting
  • Consulting with doctors and other health care professionals
  • Advising patients on healthy lifestyles and proper cardio care
  • Using equipment and technology such as magnetic resonance and tomography machines to diagnose health problems and administer treatments
  • Instructing patients on proper use of medications and possible side effects
  • Educational Requirements for Cardiologists

    Cardiology is a form of internal medicine. Before specializing in cardiology, a person must first obtain a 4-year degree and graduate from an approved medical school. Some countries offer a specialized undergraduate focus of study in pre-med.

    After graduating from medical school, most countries require that a student complete an internal medicine residency and pass an internal medicine certification exam. A subspecialization in cardiology then requires additional education and hands-on training related specifically to that field.

    Areas studied include:

  • Cardiac catheterization
  • Echocardiography
  • Nuclear cardiology
  • Electrophysiology, and pacemakers
  • Postoperative care of cardiac surgery patients
  • Emergency room care
  • Cardiovascular anatomy
  • Cardiovascular physiology
  • Cardiovascular metabolism
  • Molecular biology of the cardiovascular system
  • Cardiovascular pharmacology
  • Epidemiology
  • Biostatistics
  • Cardiovascular pathology


  • Once training is satisfactorily completed, the physician is usually required to pass additional certification testing before becoming an authorized cardiologist.

    Cardiology Career Areas

    The development of advanced technologies and treatments has led to several areas of specialization for cardiologists. Interventional cardiology involves evaluating and recommending interventional procedures, such as catheterization, balloon angioplasty, and the use of lasers and other devices that remove plaque from arteries. Electrophysiology focuses on the electrical functioning of the heart. Nuclear cardiology deals with using technology to assess and treat problems with coronary arteries, pumping functions and damage to the heart from injury or disease. Cardiologists can also specialize in Echocardiography which is the use of echocardiograms and related technology.

    Practicing cardiologists work directly with patients and may also do clinical research, publish articles, and teach residents. Cardiologists also work for drug companies, research labs, and governmental agencies. They may teach at medical schools or serve as consultants in a variety of settings. Occupational cardiology studies the relationship between stresses of different jobs and their effect on cardio health.
