Exactly What Nuclear Stress Test?

A nuclear stress test can be a non-invasive technique accustomed to measure blood circulation towards the heart while sleeping and during stress. A nuclear stress test can detect the existence of conditions for example coronary heart by which blockage or narrowing from the arteries supplying blood for the heart may occur. Although a nuclear stress test resembles a routine stress test, a radioactive substance is injected in to the bloodstream which travels towards the heart. A scanner then detects the radioactive material and fosters a picture with the heart allowing blockages to become viewed. The look shows how well blood is flowing towards the heart muscle.

The nuclear stress test is normally completed in addition to a type of exercise like the treadmill. Measuring the heart’s pumping action during exercise induced stress helps determine blockages that could limit blood circulation and impede the act of one's heart. A tiny bit of the radioactive solution can be injected right into a vein to observe the heart’s action during rest. A gamma camera then detects energy emitted in the radioactive material to watch the the flow of blood as the patient is laying sleeping.

It is generally needed that the sufferer doesn't eat or drink anything 3 to 4 hours prior to the scheduled test. The individual should talk to health related conditions about any prescription drugs which he could be taking. It is advisable to decorate in comfortable clothing and shoes because the patient is going to be over a treadmill.

Several small electrodes they fit around the patient’s chest that are then attached to a piece of equipment referred to as an electrocardiograph that monitors the heart’s electrical activity. An intravenous line (IV) is going to be inserted right into a vein within the patient’s arm. The individual will likely then get asked to start the exercise and definately will continue before radioactive substance is injected in to the IV. The individual will likely then exercise for 1 minute more. If whenever you want throughout the test, the individual feels heart problems, dizziness or difficulty breathing, he should immediately tell health related conditions. In another percentage of the exam, the sufferer will lay down beneath a scanning camera. The pictures will show the blood circulation for the heart as the patient are at rest. Test might take approximately 30 to Sixty minutes.

Patients who undergo a nuclear stress test tend to be worried about the results with the radioactive compound. Even though the most patients suffer no ill-effects in the substance, half the normal commission may feel unwanted effects like a metallic style of their mouths, headache or rash. Rare negative effects which could happens to association using the radioactive compound include joint, breathlessness, vomiting, slow heartbeat or seizure. Could also be unwanted effects with the treadmill test which might include heart problems or irregular heartrate. Patients tend to be asked to keep to get a period of time carrying out a nuclear stress test within the advent that unwanted effects may occur.
