Medical technology has interpose a long way in look care. fair a few of many include echocardiography, nuclear mental imagery, angioplasty, and ICD. every(prenominal) of which may potentially save some ones life.
Echocardiography is the subroutine of ultrasound waves apply to produce an image of the patrol wagon structure and function. A transducer, or modified microphone, turns electrical energy into sound waves, which bounces make tissues in the magnetic core and are recorded onto videotaped or information processing system disk for analysis. The test is painless, has few identified risks, and does not use radiation. Echocardiography is usually performed by a trained sonographer or technician at an office echocardiography lab, a clinic, or in a longanimouss hospital room. Throughout the test an electrocardiogram, or ECG, which records the warmnesss electrical activity, is performed to monitor the heartbeat. For transthoracic and stress echocardiography, a gel is use on the chest to improve conduction and reception- it may find cold and moist.



Echocardiography is primarily used to detect and assesses blocked coronary thrombosis arteries, enlargement of the heart, damage from high blood pressure, heart contend damage or scarring, pericardial disease and the function of the heart muscle, blood vessels and valves.
Another technological advancement in heart care is nuclear imaging. During nuclear imaging, a small loony toons of radioactive isotope is injected into the bloodstream. The radioisotope, or tracer, is carried through the bloodstream and into the myocardium, or heart muscle. Special cameras detect the radiation released from the tracers and record information more or less the heart muscle and blood flow. The information is then used to produce images of the heart on a computer assort or film. The radioactive isotopes used in nuclear imaging lose their radioactivity quickly and typically pass from the automobile trunk within 24 hours. Nuclear imaging can be done in a...If you want to get a serious essay, order it on our website: Orderessay
