The two walls meet at the apex or tip of the heart.
Patient Section, what difference does it make to me as a patient?
Each lead of the EKG represents a different portion of the heart, with adjacent leads representing a single wall (see Regular Treadmill for details).Sticky electrodes are attached to the chest, shoulders and hips and connected to the EKG portion of the Stress test machine.Meters will no longer be available on prescription after 2004.The physician can separate a normal left ventricle, from ischemia (live muscle with flow that is compromised only during exercise) and the scar tissue of a heart attack.This is followed by a "flush" injection of saline (salt water) to make sure that all of the tracer is pushed into the blood circulation.The distinction is made in the following way: normal Both the resting and stress images show uniform uptake through out the heart, as shown above.Apart from the scale, the new meter will behave and handle as reliably as the old meter.You may pause, pan left and right by dragging your mouse within the panoramic picture.Such findings indicate a previous heart attack.
Please remember that the regular stress test is heavily dependent upon interpretation of EKG changes produced by exercise.When a "perfusion tracer" (a nuclear isotope that travels to heart muscle with blood flow) is injected intravenously, it is extracted by the heart muscle in proportion to the flow of blood.You will be allowed to leave the lab and get a light snack or lunch in cases of thallium stress testing.The new 'Standard' will result in small improvements to the accuracy of the meters that have been used, and are being implemented by all the top companies who manufacture this type of medical device.Also, in the absence of reversibility there is no evidence of additional threatened or jeopardized heart muscle.As there are small differences between brands, it is worth remembering that unless you and your Doctor have the same meter, there will be small differences between readings. .The test may be stopped prior to achievement of the target heart rate if the patient develops significant chest discomfort, shortness of breath, dizziness, unsteady gait, etc., or if the EKG shows alarming changes or serious abnormal heart rhythm.It also computes the data and presents an aggregate "bull's eye" picture that compares the information to a data base of known normal cases.Specific heart medicines may need to be stopped one or two days prior to the test.The scientists who devised the new standard for peak flow meters believed that if the 'standard range' foxit reader for win 7 64 bit peak flow meter could be made more accurate, there would be no need for a 'low range' meter.
