Description

An echocardiography is an ultrasound examination of a patient's heart, which produces a two-dimensional picture. This information evaluates the condition of the patient's heart (the function of the heart muscle and valves of the heart). To perform the test, the patient lies down on a bed, conducting gel is applied to the chest and a probe is placed on the chest which is moved around to obtain pictures of the heart from different angles. What is STRESS TEST: Exercise stress testing is used to assess a patient's response of their heart, lungs and muscles to exercise. The test obtains measurements related to the metabolic, cardiovascular and pulmonary adaptations of the patient from rest to maximum exercise and recovery. The exercise test is performed by a technologist and a physician experienced in exercise testing in a carefully controlled setting. The MDU can exercise patients by having them walk on a treadmill or pedal a bicycle. Every few minutes the elevation and/or speed of the treadmill is increased and pedal resistance is increased on the bike. Heart rate, electrocardiogram, collecting and analyzing expired air, oxygen saturation and blood pressure are monitored during cardiopulmonary stress testing. The Bruce Protocol (max study) or Naughton Protocol (submax study) are used for basic Cardiac Assessment with the heart rate, electrocardiogram and blood pressure being monitored. The test continues until the patient reaches his/her maximum exercise tolerance or pre-determined safety limits have been exceeded.
