Most importantly, there are three types of stress tests: exercise stress tests, nuclear stress tests, and stress echocardiograms.
Exercise stress test: You will walk on a treadmill or ride a bicycle slowly. A healthcare provider will place several electrodes on your arm, chest, and legs. These electrodes are attached by wires to an electrocardiogram (EKG) machine, which records your heart’s electrical activity.
Nuclear stress test: This test helps your doctor to know which parts of your heart are healthy and working well and which do not. You’ll get a shot of a very small and harmless amount of radioactive substance, then your doctor will use a special camera to see the blood flow to your heart muscle. This will be done first while you’re at rest and again after you exercise.
Blood test: Blood tests like CBC, hormones tests can be used to estimate how much stress one is experiencing. A cortisol blood test is one of the vital parameters commonly used in blood tests. Cortisol is a hormone that is released by the adrenal glands when one is under stress. Higher levels of cortisol would indicate higher levels of stress.
