Final answer:
Cardiology is the study of the heart, and cardiologists are the medical professionals who specialize in heart diseases. They undergo extensive education and training and can diagnose conditions using various tests such as ECG and chest X-rays.
Step-by-step explanation:
The study of the heart is known as cardiology. Cardiologists are medical professionals who specialize in diagnosing and treating diseases of the heart. They undergo extensive education and training, including 4 years of medical school, a three-year residency in internal medicine, and over three additional years specializing in cardiology. These experts are well-versed in administering and interpreting tests such as electrocardiograms (ECG) and chest X-rays to diagnose conditions like heart failure and thereafter prescribe suitable treatments.
After their training, cardiologists take a rigorous examination from the Board of Internal Medicine to become board-certified. They might also receive special recognition by becoming a Fellow of the American College of Cardiology (FACC), which is based on merit and contributions to the field of cardiovascular medicine. The heart's structure and function, its anatomy including coronary circulation, and the physiological details including the cardiac cycle are all essential subjects within cardiology.
