Electrocardiograms record those electrical impulses of the heart that allow it to pump blood through the body. Damage to heart muscle can be determined by evaluating disruptions or changes in these impulses.
CARDIAC ULTRASOUND OR ECHOCARDIOGRAPHY
Cardiac Ultrasound or Echocardiography is "Doppler" technology, similar to underwater sonar, is used to assess the structure and function of the heart muscle, pump and valves.
The Transesophageal approach to echocardiography allows your physician to more accurately assess heart valves, congenital defects and other structural abnormalities. This is an extremely valuable tool for use before, during and after surgery.
Nuclear Medicine uses radioisotopes injected into the blood stream, which attach to red blood cells allowing your doctor to assess blood flow to your heart with images acquired by a gamma camera.
High-tech computers and monitor are used to study patterns and rhythms of the heart during exercise activity on a treadmill.
Ultrasound and other techniques are used to assess blood flow and the patient's overall vascular system.
