High blood pressure Other aspects of heart disease may lead to an abnormal EKG. For example, people with high blood pressure are more likely to have an abnormal EKG reading.
An ECG can show heart rhythm irregularities (arrhythmias). These conditions may occur when any part of the heart’s electrical system malfunctions. In other cases, medications, such as beta blockers, cocaine, amphetamines, and over-the-counter cold and allergy drugs, can trigger arrhythmias. Heart attack.
Moreover, How do you know if your ECG is abnormal?
– chest pain or discomfort.
– difficulty breathing.
– heart palpitations or feeling your heart beating oddly.
– the feeling that you might pass out.
– racing heart.
– the feeling that your chest is being squeezed.
– sudden weakness.

Can anxiety cause an abnormal EKG reading?
Premature ventricular contractions is one of the manifestations of sympathetic over activity due to anxiety. However, anxiety might induce electrocardiographic (ECG) changes in normal person with normal heart, as in this documented case.
What is a normal ECG reading?
Normal intervals Normal range 120 – 200 ms (3 – 5 small squares on ECG paper). QRS duration (measured from first deflection of QRS complex to end of QRS complex at isoelectric line). Normal range up to 120 ms (3 small squares on ECG paper).
Can anxiety cause abnormal EKG?
Premature ventricular contractions is one of the manifestations of sympathetic over activity due to anxiety. However, anxiety might induce electrocardiographic (ECG) changes in normal person with normal heart, as in this documented case.
What is a normal ECG tracing?
A normal ECG trace includes a P wave, a QRS complex and a T wave.
What should you not do before an EKG?
– Avoid oily or greasy skin creams and lotions the day of the test. They interfere with the electrode-skin contact.
– Avoid full-length hosiery, because electrodes need to be placed directly on the legs.
– Wear a shirt that can be easily removed to place the leads on the chest.
Can anxiety throw off an EKG?
“An ECG is usually reliable for most people, but our study found that people with a history of cardiac illness and affected by anxiety or depression may be falling under the radar,” says study co-author Simon Bacon, a professor in the Concordia Department of Exercise Science and a researcher at the Montreal Heart Nov 11, 2010
What position should the patient be put in when preparing for an EKG?
The standard 12-lead ECG is generally performed with the patient lying quietly in the supine position. Care should be taken to ensure that the skin is clean and trimmed of excess hair in the areas in which the leads are to be placed.
What should you not do before an ECG?
Avoid drinking cold water or exercising before your EKG. Drinking cold water can cause changes in the electrical patterns that the test records. Exercise can increase your heart rate and affect the test results.
Can I drink coffee before an EKG?
Avoid all products that contain caffeine for 24 hours before the test. In general, caffeine is found in coffee, tea, colas and other soft drinks, most chocolate products, as well as strawberries (these contain a small amount of caffeine), as caffeine will interfere with the results of the test.
Can an EKG give false results?
The study of 500 patients found a false positive reading between 77 and 82 percent in patients screened by electrocardiogram, and a false negative reading between 6 percent to 7 percent in the same patient population.
What should I do before an ECG?
– Avoid oily or greasy skin creams and lotions the day of the test because they can keep the electrodes from making contact with your skin.
– Avoid full-length hosiery, because electrodes need to be placed directly on your legs.
– Wear a shirt that you can remove easily to place the leads on your chest.
How can you tell if an ECG is abnormal?
ECG measurements reveal if the electrical activity is unusually fast, slow, or irregular. The test can also show if your heart is enlarged or has poor blood flow.
