The ECG will not harm you. However, it can sometimes show mild nonspecific abnormalities that are not due to underlying heart disease, but cause worry and lead to follow-up tests and treatments that you do not need.
Does being nervous affect ECG?
T-wave alternans, as well as other ECG measures of heterogeneity of repolarization, increases with emotional and cognitive stress in the laboratory setting, and may also increase with stress in “real life” settings. In the atrium, stress impacts components of the signal-averaged ECG.

An echocardiogram is a common test. It gives a picture of your heart using ultrasound. It uses a probe either on your chest or sometimes can be done down your oesophagus (throat). It helps your doctor check if there are any problems with your heart’s valves and chambers, and see how strongly your heart pumps blood.
What does a healthy ECG look like?
Share on Pinterest An EKG displays P Waves, T Waves, and the QRS Complex. These may have abnormalities in people with A-fib. A “normal” EKG is one that shows what is known as sinus rhythm. Sinus rhythm may look like a lot of little bumps, but each relays an important action in the heart.
Should I worry about an abnormal EKG?
An abnormal EKG can mean many things. Sometimes an EKG abnormality is a normal variation of a heart’s rhythm, which does not affect your health. Other times, an abnormal EKG can signal a medical emergency, such as a myocardial infarction (heart attack) or a dangerous arrhythmia.
Can a chest xray show heart blockage?
Chest X-rays can show changes or problems in your lungs that stem from heart problems. For instance, fluid in your lungs can be a result of congestive heart failure.
Can you have a heart attack with a normal EKG?

The next step is an evaluation by a doctor or other clinician, who will ask about your medical history and details about the location, duration, and intensity of your symptoms.
What can an ECG diagnose?
