Clinical cardiologists typically referred by a primary doctor who suspects heart disease or related conditions. Patients may require a focused treatment plan or invasive surgery to resolve heart problems. A cardiologist may treat congenital heart conditions,
endocarditis (an inflammation of the heart), pericarditis (an inflammation of the tissue surrounding the heart), high blood pressure and irregular heart rhythms.
These are all serious conditions. Many different techniques are used to diagnose and treat heart patients, including the use of echocardiography, which record heartbeats and abnormal rhythms. Some clinical cardiologists perform surgeries or insert stents into their patients.
