What are the abnormalities in ECG?
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 anxiety cause an 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 causes abnormal ECG results?
If your electrolytes are imbalanced, you may have an abnormal EKG reading. Heart attack or ischemia: During a heart attack, blood flow in the heart is affected and heart tissue can begin to lose oxygen and die. This tissue will not conduct electricity as well, which can cause an abnormal EKG.
What is the normal ECG report?

Can high blood pressure cause abnormal 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.
How do you know if an ECG is normal?
Normal range up to 120 ms (3 small squares on ECG paper). QT interval (measured from first deflection of QRS complex to end of T wave at isoelectric line). Normal range up to 440 ms (though varies with heart rate and may be slightly longer in females)
