An ECG (electrocardiogram) records the electrical activity of your heart at rest
. It provides information about your heart rate and rhythm, and shows if there is enlargement of the heart due to high blood pressure (hypertension) or evidence of a previous heart attack (myocardial infarction).

Futhermore, is ECG enough to detect heart problems?
Electrocardiograms, which monitor the heart's electrical patterns, don't reliably reveal the risk of having a heart attack. Unless you have symptoms of a heart problem, taking a cautionary look under the hood is unlikely to help—and could even be harmful.
So, why is ECG so important? An ECG is used to see how the heart is functioning. It mainly records how often the heart beats (heart rate) and how regularly it beats (heart rhythm). It can give us important information, for instance about possible narrowing of the coronary arteries, a heart attack or an irregular heartbeat like atrial fibrillation.
Afterall, what heart problems can be detected by an ECG?
Electrocardiogram (ECG or EKG) to assess the heart rate and rhythm. This test can often detect heart disease, heart attack, an enlarged heart, or abnormal heart rhythms that may cause heart failure. Chest X-ray to see if the heart is enlarged and if the lungs are congested with fluid.
Can an ECG detect angina?
Diagnosing angina Your doctor can suspect a diagnosis of angina based on your description of your symptoms, when they appear and your risk factors for coronary artery disease. Your doctor will likely first do an electrocardiogram (ECG) to help determine what additional testing is needed to confirm the diagnosis.

an echocardiogram. Although they both monitor the heart, EKGs and echocardiograms are two different tests. An EKG looks for abnormalities in the heart's electrical impulses using electrodes. An echocardiogram looks for irregularities in the heart's structure using an ultrasound.
The results of the EKG will be available immediately. If you had your EKG in the doctor's office, your doctor may go over your results with you right then. Typically, though, your doctor will also have cardiologist (a doctor who specializes in heart health) review your results, too.
Heart block, also called the atrioventricular block, is when the electrical signal that controls your heartbeat is either partially or completely blocked. This makes the heart beat slow or skip beats and the heart cannot pump blood effectively. Valvular defects cannot be detected using an ECG.
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.
Chest pain could be angina if it: feels tight, dull or heavy – although some people (especially women) may have sharp, stabbing pain. spreads to your arms, neck, jaw or back.
Median expectation of life at age 70 years was reduced by about 2, 5 and 6 years for those with angina, myocardial infarction, or both, respectively.
New high-sensitivity blood tests allow detection of a very low level of troponin soon after the onset of symptoms. The electrocardiogram (ECG) measures the heart's electrical activity and can show abnormalities in a heart attack.
You may not be able to get the results of your ECG immediately. The recordings may need to be looked at by a specialist doctor to see if there are signs of a possible problem. Other tests may also be needed before it's possible to tell you whether there's a problem.
