Generally, to become a cardiologist in the United States, an individual must first complete a bachelor's degree (4 years), followed by medical school (4 years), then a residency in internal medicine (3 years), and finally a fellowship in cardiology (3 years).

Individual circumstances such as the timing of exams, research, and other aspects could further influence the actual timeline to becoming a cardiologist.
