I think your talking about the machine they use outside your body, placed on your chest and it shows a picture of your heart on a screen? This would be called an Ultrasonagraphy machine. The test is nearly always done by a certified ultrasonagrapher who knows how to read what is showing on the screen.
You use a heart rate machine
Sorry to burst your bubble but actaully, there is no such thing as a lie detector! What they use in jail is a machine that tells when your heart rate goes up. When you get nervous your heart pounds very fast, it basically detects that. So when you lie (unless you're a professional) your heart rate goes up and the machine detects it. You should use that!
It is a machine that detects changing in blood pressure, heart rate and other body rhythems to detect false statements.

Heart rate monitors are used to monitor heart rate on a longer-time basis. You can buy heart rate monitors between £10-500. You can use them whilst you are exercising so that you avoid the risks of exceeding your maximal heart rate.
to prevent using a heart lung machine you could excercise regularly to keep your heart strong
A doctor can measure a person's heart rate by putting electrodes on the chest. This is called a electrocardiograph. A person's heart rate can also be taken by their pulse.
A lot of agents can affect heart rate, but let's say... Cocaine (accelerates the heart rate) Adrenaline (accelerates the heart rate) Potassium chloride (reduces it to zero - this is the chemical they use in executions to make the heart stop)
Basic Elliptical Machine RoutineAn elliptical machine is one of the pieces of exercise equipment that you can use at the gym or at home. It is a great way for you to lose weight and build the muscles in your body. There is a console on the elliptical that will tell you how fast you are going and how long you have been exercising. There are several programs in the console that will allow you to exercise on the level you need.When you begin using the machine, you can start on a basic program. Your legs will move more freely than with a treadmill because it is similar to climbing stairs or jogging. You don't have to use your arms on the handles when starting out, but as you increase your speed and you get near the end of your routine, you should use the handles to stabilize your body.After your warm-up, you can increase your speed and the length of how far you walk. You need to use the handles to keep your balance and to make sure you do not get hurt. The heart rate will increase and you will begin to feel the muscles in your body warm to the movement of your body. This is similar to jogging on a treadmill. The longer you use the machine and you want to work out, the higher you can increase the resistance on the machine. Working out on an elliptical is a safe workout, and you can get in shape quickly if you use the machine every day. When you have reached the peak of your routine, you can slow the resistance down and walk slower. Your heart rate will be displayed on the console and as you slow your routine, your heart rate will come down. You want to adjust your heart rate like a hill in order to get the most of your workout. You should start at a normal rate. As you exercise, your rate should rise to a maximum level. When you start to slow your routine down, the heart rate will come back down to a normal level.
