What is an Exercise Electrocardiogram?

An electrocardiogram (ECG), which is a quick test to assess the heart, is simple and inexpensive. To perform the test, small, adhesive patches are applied to the skin at specific points on the chest, arms, legs. The electrodes connect to an ECG machine via wires. The electrical activity in the heart is then measured and interpreted. Finally, it is printed. There is no electricity sent to the body.

Natural electrical impulses coordinate contractions among the various parts to maintain blood flow. The ECG records these impulses in order to determine how fast the heart beats and what rhythm it is keeping. It also shows the strength and timing for the electrical impulses that travel through different parts of your heart. ECG changes can indicate many heart-related conditions.

A stress ECG is used to evaluate the heart's reaction to exercise or stress. While you are on a treadmill, stationary bike, or other exercise equipment, your ECG will be recorded. An ECG tracing will also be taken during the test in order to assess the impact of increasing stress on your heart. Intensity and speed on the treadmill will be gradually increased in order to make the exercise more difficult. You will pedal faster on a bike if there is more resistance. You'll be asked to keep going until your heart rate reaches a certain level (determined by your health provider based on your age, physical condition, and other factors) or until you become unable to do so due to fatigue, shortness of breath or other symptoms.

Why do I need an electrocardiogram for exercise?

A variety of reasons may lead your healthcare provider or doctor to request an exercise electrodecardiogram (ECG).

If you think you may have coronary-artery disease (blocked blood vessels in the heart), your doctor will assess your tolerance to stress and exercise.

To determine safe exercise limits prior to starting a cardio rehab program or recovering from a cardiac event like a heart attack (myocardial Infarction or MI)

To determine heart rhythm during exercise and electrical activity

To monitor heart rate during exercise.

You might also recommend an ECG to your doctor if you have other medical reasons.

What are the possible risks of an exercise electrodecardiogram?

The test is stressful on the heart and there is little chance for it to fail.

Severe heart rhythm problems

It is possible to feel uncomfortable after the electrodes are removed. It is possible for the electrodes to stick too long, causing tissue damage and skin irritation.

There could be additional risks, depending on your particular medical condition. Discuss any concerns with your healthcare provider prior to the procedure.

Certain conditions and factors may affect or interfere with an ECG.

Consume a substantial meal prior to the test

Before the test, take caffeine

You must have not smoked or used any other tobacco products prior to the test

High blood pressure

Electrolyte imbalances are when there is too much, too little, or too many potassium, magnesium, and calcium in the blood.

It might be difficult to raise your heart rate to the target levels with certain medications, such as beta blockers.

Heart valve disease

Increased heart

Arrhythmias
