What does a Q wave mean on a ekg?

What does a Q wave mean on a ekg?

EKG : The ekg has waves with amplitude and direction. A q wave reflects a lack of electrical force in a certain direction. This lack of force has some correlation when a change in pattern with a loss of muscle as is seen in heart damage like a heart attack. ...Read more

What does a "q-wave" mean on an ekg?

What does a "q-wave" mean on an ekg?

It depends: Sometimes it can just be a normal variant, sometimes reflects an old heart attack. Your physician can tell you which of the two it is. ...Read more

What is borderline inferior Q wave mean?

What is borderline inferior Q wave mean?

ECG finding: Inferior q waves on ECG indicate possible prior inferior wall myocardial infarction (heart attack). To be significant, the q wave must be at least 25% or more in amplitude compared to following r wave, and be 1 mm wide. If it does not meet these criteria, it is a "borderline" q wave, and is less likely to indicate a prior heart attack. ...Read more

Does Q wave always mean you had a heart attack?

Does Q wave always mean you had a heart attack?

Ecg: Q waves mean either electrical force going away from the lead axis being examined or lack of force in the direction of the lead. This is often due to heart muscle damage but not always. ...Read more

My dad had a MI 3mths later on ECG the report said inferolateral st sagging and 'surprisingly no q wave' what does this mean?

My dad had a MI 3mths later on ECG the report said inferolateral st sagging and  'surprisingly no q wave' what does this mean?

Pathological q waves: Are changes commonly seen on the EKG after a heart attack. They reflect an area of damage or scarring. Usually they are a permanent change on the EKG, But sometimes they disappear. That's why the report said " surprisingly no q waves". ...Read more

What does isolated narrow Q wave in lead 3 mean, flat t waves across all leads, mild sigmoid septal bulge. Does this all relate to hole in heart ?

What does isolated narrow Q wave in lead 3 mean, flat t waves across all leads, mild sigmoid septal bulge. Does this all relate to hole in heart
?

Non specific finding: The findings you describe sound non-specific, and may occur for multiple reasons. The ekg does not usually diagnose a hole in the heart, but it can give information about how the heart is responding if the hole is causing additional stress on the heart function. ...Read more

I got my ECG results and my Q wave was abnormal. Does this mean that I had a heart attack?

I got my ECG results and my Q wave was abnormal. Does this mean that I had a heart attack?

It depends: It depends on the location and size of the q waves in relation to the other parts of the qrs complex. Ask your doctor to look at the ECG and let you know. ...Read more

What is the definition of non-q-wave infarction?

What is the definition of non-q-wave infarction?

EKG diagnosis: When a piece of heart muscle dies, it no longer has electrical activity. This shows up on an ekg as a q wave. If someone clinically has a heart attack but the ekg never evolves q waves, it is (by definition) a "non-q wave" mi. ...Read more

What does a Q wave on a stress test represent?

Heart Damage: A "q wave" is seen on an electrocardiogram (ekg) several of which are recorded during a stress test. Q waves may be very small and not carry much significance or may be larger and suggest that heart damage by a heart attack has occured at some point in time. Further testing and imaging of the heart may be required to determine if the q wave is significant. ...Read more
