Cardiology is a branch of Medical science dealing with disorders of the heart and circulatory system. The field includes tests and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heartdisease and electrophysiology. Physicians or doctors specializing in this field of medicine are called cardiologists. Cardiologists should not be confused with cardiac surgeons, cardiothoracic, and cardiovascular who are surgeons who perform cardiac surgery - operative procedures on the heart and great vessels.

ð Disorders of pericardium (eg:Pericarditis, Pericardial tamponade)
ð Disorders of heart valves (eg:Aortic valve disorders, Mitral valve disorders)
ð Disorders of the electrical system of the heart (eg:Tachycardia, Cardiac arrhythmias)
ð Inflammation and infection of the heart (eg:Endocarditis, Myocarditis)
ð Congenital heart disease (eg:Atrial septal defect, Ventricular septal defect)
ð Vascular diseases (eg: Vasculitis, Atherosclerosis)

Devices used in cardiology
ð Stethoscope
ð Pacemaker
ð Defibrillator

Diagnostic tests and procedures
ð Blood tests
ð Echocardiogram
