management assignments ECG

Heart disease is one of the main causes of death in the world at present. One way to pick up a possible problem with your heart is on an ECG. An exercise electrocardiogram (EKG or ECG) is a test that checks for changes in your heart while you exercise. Sometimes ECG abnormalities can be seen only during exercise or while symptoms are present. This test is sometimes called a “stress test” or a “treadmill test.” During an exercise ECG, you may either walk on a motor-driven treadmill or pedal a stationary bicycle.

An exercise ECG translates the heart’s electrical activity into line tracings on paper. The spikes and dips in the line tracings are called waves. A resting ECG is always done before an exercise ECG test, and results of the resting ECG are compared to the results of the exercise ECG. A resting ECG may also show a heart problem that would make an exercise ECG unsafe.

An exercise electrocardiogram is done to:

  • Help find the cause of unexplained chest pain.
  • Help decide on the best treatment for a person with angina.
  • See how well people who have had a heart attack or heart surgery are able to tolerate exercise.
  • Help find the cause of symptoms that occur during exercise or activity, such as dizziness, fainting, or rapid, irregular heartbeats (palpitations).
  • Check for a blockage or narrowing of an artery after a medical procedure, such as angioplasty or coronary artery bypass surgery, especially if the person has chest pain or other symptoms.
  • See how well medicine or other treatment for chest pain or an irregular heartbeat is working.
  • Help you make decisions about starting an exercise program if you have been inactive for a number of years and have an increased chance of having heart disease.

Exercise electrocardiograms are not recommended if you’re healthy and have no symptoms of heart disease. tu delft phd thesis How to Prepare for an ECG

If you are planning to have an ECG, here are some tips on how to prepare. Make sure to tell your doctor if you:

  • Are taking any medicines, including a medicine for an erection problem (such as Viagra). You may need to take nitroglycerin during this test, which can cause a serious reaction if you have taken a medicine for an erection problem within the previous 48 hours. Ask your doctor whether you need to stop taking any of your other medicines before the test.
  • Are allergic to any medicines, such as those used to numb the skin (anesthetics).
  • Have had bleeding problems or take blood-thinners, such as aspirin or warfarin (such as Coumadin).
  • Have joint problems in your hips or legs that may make it hard for you to exercise.
  • Are or might be pregnant.

  • You think you are having a heart attack.
  • You are having chest pain that is not relieved with rest (unstable angina).
  • You have high blood pressure that is not controlled with medicine.
  • You have untreated, life-threatening irregular heart rhythms (arrhythmias).
  • You have severe narrowing of one of your heart valves (aortic valve stenosis).
  • You have an infection in your heart muscle (myocarditis).
  • You have a severe decrease in the amount of red blood cells (anemia).
  • You have a stretched and bulging section in the wall of the large artery that carries blood from the heart (aortic aneurysm) or in one of the chambers of the heart (ventricular aneurysm).
  • You have severe lung disease.

An exercise electrocardiogram is usually done in a doctor’s office, clinic, or hospital lab by a health professional or doctor. research paper helper need help essay writing Before the test

  • Remove all jewelry from your neck, arms, and wrists. Wear flat, comfortable shoes and loose, lightweight shorts or sweat pants. Men are usually bare-chested during the test. Women often wear a bra, T-shirt, or hospital gown. Avoid wearing any restrictive clothing other than a bra. You may want to stretch your arm and leg muscles before beginning.
  • Areas on your arms, legs, and chest where small metal discs (electrodes) will be placed are cleaned and may be shaved to provide a clean, smooth surface to attach the discs. A special EKG paste or small pads soaked in alcohol may be placed between the discs and your skin to improve conduction of the electrical impulses, but in many cases disposable discs are used that do not require paste or alcohol.
  • The electrodes are hooked to a machine that traces your heart activity onto a piece of paper. Your chest may be loosely wrapped with an elastic band to keep the electrodes from falling off during exercise. A blood pressure cuff will be wrapped around your upper arm so that your blood pressure can be checked every few minutes during the test.

For exercise, you typically either walk on a treadmill or pedal on a stationary bicycle while being monitored by an ECG machine. Your ECG will be monitored on screen, and paper copies will be printed out for later review before you start the exercise, at the end of each section of exercise, and while you are recovering.

The test is usually performed in a series of stages, each lasting 3 minutes. After each 3-minute stage, the resistance or speed of the treadmill or bicycle is increased.

  • In both the treadmill and the bicycle tests, your ECG, heart rate, and blood pressure will be recorded during the exercise. Your heart rate and ECG will be recorded continuously. Your blood pressure is usually measured during the second minute of each stage. It may be measured more frequently if the readings are too high or too low.
  • The test continues until you need to stop, until you reach your maximum heart rate, until you begin to show symptoms of stress on your heart and lungs (such as fatigue, extreme shortness of breath, or angina), or until the ECG tracing shows decreased blood flow to your heart muscle.
  • The test may also be stopped if you develop serious irregular heartbeats or if your blood pressure drops below your resting level.

  • You will be able to sit or lie down and rest.
  • Your ECG and blood pressure will be checked for about 5 to 10 minutes during this time.
  • The electrodes are then removed from your chest, and you may resume your normal activities.

The entire test usually takes 15 to 30 minutes. ivy college admission essay Results

Your doctor will look at the pattern of spikes and dips on your electrocardiogram to check the electrical activity in different parts of your heart. The spikes and dips are grouped into different sections that show how your heart is working.

  • You reach your target heart rate, based on your age, and can exercise without chest pain or other symptoms of heart disease.
  • Your blood pressure increases steadily during exercise.
  • Your ECG tracings do not show any significant changes. Your heartbeats look normal. college admission essay online requirements Abnormal results may include:
