The process of reflecting ultrasound Doppler signals off the heart and
surrounding anatomical structures to visualize cardiac activity and
structure, and facilitate diagnosis.
Accumulation of an excessive amount of watery fluid in cells, tissues or
A diagnostic test that records the electrical activity of the brain.
Electrodes are laced on different locations of the scalp, and the difference

Exercise Tolerance Testing
Stress test; a diagnostic test in which the patient exercises on a
treadmill, bicycle, or other equipment while heart activity is monitored by
Removal of a tube from an organ, structure, or orifice; specifically,
