A Pacemaker is a small device implanted under the skin that sends electrical signals to start or regulate a slow heartbeat. It is a popular treatment option.
An ICD (Implantable Converter Defibrillator) is a small device that is similar to pacemaker and implanted in the body, often just under the collarbone. ICDs deliver small electrical shocks to regulate the heart rate.
This procedure can help doctors diagnose a number of heart conditions, including coronary artery disease and defective heart valves. During the procedure, a doctor inserts a thin plastic tube (catheter) into an artery or vein in the arm or leg where it is then advanced into the heart or coronary arteries. Cardiac Catheterization is used to get information about the pumping ability of the heart.
Cardiac Interventions are procedures that use specialized catheters to open up clogged arteries. Cardiac interventions include balloon angioplasty and the insertion of stents to keep arteries open.
Catheters can also be used to open up kidney arteries and other arteries in the lower body that have become diseased. These procedures are performed by a cardiologist.
