Electrocardiogram (Overview)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface can indicate underlying disease.

What is an electrocardiogram (ecg) used for?

Check your heart: An ekg (ECG) collects information about how the electrical impulse that maintains your heart rate is transmitted through your heart. It not only shows the rate of your hearbeat and its regularity or lack of, but can also give information about the size and strength of the chambers of your heart and sometimes about whether the heart muscle has been damaged, is receiving enough blood, etc. ...Read more

Can you please give me more information on what a left ventricular fascicilar block entails. Showed up on EKG and dr. Is down playing it. Thanks?

Can you please give me more information on what a left ventricular fascicilar block entails. Showed up on EKG and dr. Is down playing it. Thanks?

Electrical: Normal conduction through the heart arises in the right atrium and proceeds into the 2 ventricles, one pathway to the r ventricle and 2 pathways to the l: the anterior and posterior fascicles. Left anterior fascicular block causes no symptoms and requires no treatment but is sometimes associated with hypertension and coronary artery disease. Less commonly valvular disease. ...Read more

What is the purpose of having t.Waves, q.T. Intervals, long q.T syndrome studies with stress & EKG tests for? What are they and what reason/diagnosis?

What is the purpose of having t.Waves, q.T. Intervals, long q.T syndrome studies with stress & EKG tests for? What are they and what reason/diagnosis?

Arrythmia: The different waves on the ekg represent the electrical impulses reaching different parts of the heart as it beats. Long qt syndrome is a condition where the electrical signals take longer than normal to pass through the heart. It may be caused by medication or may be congenital. Long qt may progress to life-threatening arrhythmias, so it is important to be monitored by your doctor frequently. ...Read more

What general areas can an electrocardiogram (ekg) measure?

Many possibilities: Ekg can help diagnose heart attacks, rapid or slow heart beats, abnormalities of the conduction system that synchronizes the heartbeat, thickening of the heart muscle, certain chemical abnormalities or medication overdoses in the blood, disease of the pericardium, and many other conditions. Even strokes, lung, thyroid, and other non-cardiac diseases can affect the ekg. ...Read more

41 female, in june had excer strs test EKG chst xray bloodwork all normal I do smoke and I am on BP med pressunder control. Safe to say my heart is ok?

41 female, in june had excer strs test EKG chst xray bloodwork all normal I do smoke and I am on BP med pressunder control. Safe to say my heart is ok?

Heart health: While the test results you report are good news, they do not necessarily prove that your heart is healthy. Smoking can cause heart disease, and a conventional exercise stress test may not identify coronary artery disease, especially in females. Quitting smoking will reduce risk, and a nuclear stress test may give more information. ...Read more

Chest pain below left nipple, left arm pain. Various painful twinges going on 2yrs. Ecg/blood/x-ray/ct/stress test/gastro scope/ultrasound ok, ideas?

Not heart: This sounds like musculoskeletal pain. At age 26, it's not likely to be your heart. With pain in your left arm and chest, it could be coming from your neck. There are nerves that exit your spinal cord through the vertebrae in your neck. If these nerves are compressed, they can cause arm pain. Do you do repetitive motion (like weight lifting?) left handed? Observe what you do with your body! ...Read more

Hi my left arm feels cold. And hurts abit was diagnosed with shingles over a week a go but that never happend. Had ECG was clear?

Hi my left arm feels cold. And hurts abit was diagnosed with shingles over a week a go but that never happend. Had ECG was clear?

Atypical: Your symptoms are atypical for angina and you are young. Shingles usually burns and is painful. Still shingle can have many features and symptoms. You don't even have to see a rash to be diagnosed with it. Other causes could be vasospasm or blocked arteries to arm. Pinched nerves as well. Go back for follow up and see if more testing is needed to sort things out. ...Read more

How accurate is an electrocardiogram?

EKG: Is a useful test. It depends what we order it for. All people with hypertension should have a baseline ekg, we like to compare an old ekg when pt gets another ekg when having angina. Ekg can detect heart attach changes (not all the time). So, it is important to have a doctor order, and interpret ekg on the right clinical scenario. ...Read more
