What does an EKG not tell you?
An EKG Has Limits
It measures heart rate and rhythm—but it doesn't necessarily show blockages in the arteries unless they are causing acute loss of blood flow to the heart muscle.
What ECG Cannot detect?
An ECG can help detect:
- arrhythmias – where the heart beats too slowly, too quickly, or irregularly.
- coronary heart disease – where the heart's blood supply is blocked or interrupted by a build-up of fatty substances.

What is the best test to check for heart problems?
A coronary angiogram is a type of X-ray used to examine the coronary arteries supplying blood to your heart muscle. It's considered to be the best method of diagnosing coronary artery disease - conditions that affect the arteries surrounding the heart.Can an EKG detect a blood clot?
An EKG records the heart's electrical activity. When there is a blood clot near the heart, the heart has to work harder to circulate the blood, which can sometimes be detected by an EKG. My EKG results showed that I had a massive pulmonary embolism, which is a blood clot in the lungs.What does anxiety look like on an EKG?

When anxiety is the trigger, heart rate typically increases steadily rather than suddenly.What does fluttering look like on EKG?
Atrial flutter is an abnormal, rapid heartbeat that produces a "sawtooth" pattern on an electrocardiogram.What 5 abnormalities can be found on the echocardiogram?
The echocardiogram can help detect:
- Abnormal heart valves.
- Congenital heart disease (abnormalities present at birth)
- Damage to the heart muscle from a heart attack.
- Heart murmurs.
- Inflammation ( pericarditis ) or fluid in the sac around the heart (pericardial effusion)
Can an EKG show lung problems?
Electrocardiography (ECG) is a useful adjunct to other pulmonary tests because it provides information about the right side of the heart and therefore pulmonary disorders such as chronic pulmonary hypertension and pulmonary embolism.Can a EKG detect a stroke?
Can an ECG detect stroke? Yes. ECG can detect a heart problem that might lead to a stroke or even uncover a past problem such as a previous heart attack. Such ECG results would be classified as abnormal ECG.What are the early signs of heart blockage?
