Cardiologists and pediatric heart doctors train on separate tracks
Cardiology studies the heart and vessels as a branch of internal medicine, yet adult and child pathways diverge completely. An adult cardiologist is not trained to manage paediatric hearts, and the reverse is also true. In the United States the route is three years of internal medicine plus three of cardiology fellowship.
The name fuses Greek kardiā (heart) with -logia (study), and the field sits inside internal medicine. Practitioners diagnose and treat congenital defects, coronary disease, heart failure, valve problems, and arrhythmias, while operations belong to surgeons. Children's heart specialists form a separate discipline with their own training, so neither group is equipped to cover the other's patients. American trainees spend a three-year residency in general internal medicine before a three-year cardiology fellowship, then may add a recognised sub-specialty such as interventional work. According to Doximity, adult cardiologists in the U.S. earn about $436,849 a year on average.
Britain asks two foundation years, three of internal medicine, MRCP exams, then a five-year cardiology programme. In India the post-school path to cardiologist can stretch about eleven and a half years through entrance exams and MBBS. Electrophysiologists map the heart's wiring with intracardiac catheters and programmed stimulation to chase complex arrhythmias and test drug regimens against future ventricular tachycardia or fibrillation. U.S. training after medical school often totals eight years including two dedicated to electrophysiology.
Echocardiographers use two- and three-dimensional ultrasound plus Doppler—and often transesophageal probes during procedures—to quantify chambers, valves, and congenital anatomy with higher resolution than chest-wall scans alone. Among older adults, coronary disease, myocardial infarction, heart failure, cardiomyopathy, and atrial fibrillation drive heavy mortality, while atherosclerosis and peripheral artery disease add morbidity. Catheter-based interventional cardiology—angiograms, angioplasty, atherectomy, stents—spares patients surgical scars and long recoveries, and primary angioplasty is now the gold-standard treatment for an acute heart attack.
