A 30-year-old female asked:

what does it mean if your ecg shows t wave inversion from v1- v4 ?

Dr. Bradley Radwaner
Cardiology 41 years experience
Abnormal ECGS: T wave inversions are an abnormal electrical pattern on an ECG which can indicate a heart problem. Most serious would be an indication of ischemia, or lack of blood flow to a part of the heart muscle. This occurs when there are cholesterol blockages in the coronary arteries. Other less dangerous causes for these changes include high blood pressure, leaky valves and thickened heart muscle.
Dr. Steven Ajluni
Cardiology 35 years experience
Compare w previous: While anterior t wave inversion can be a sign of ischemia (reduced blood supply) to heart tissue, it can also occur in young people as a result of persistence of a finding that is more commonly seen in juveniles (persistence of a juvinile pattern). This might be possible in a 30 yo. Previous ecg's might be helpful to see if this is a change from your baseline. Evaluation by your doc.

A 39-year-old member asked:

Is a small Q wave on an ECG significant?

1 doctor answer3 doctors weighed in
Dr. Samuel Hahn
Cardiology 28 years experience
Probably not: By definition, a "significant" Q wave must be > than 40 msec in duration or > than 25-33% (depends on the reference) of the R wave height. Even by that criteria, many electrocardigraphically significant Q waves are seen in people with normal cardiac echo's and mri's.

What does a Q wave mean on a ekg?

Dr. Ankush Bansal
Internal Medicine 17 years experience
Old infarct: A Q wave means an old infarct (a previous heart attack) that resulted in permanent death of a part of the heart muscle. Depending on the location, extent, and other co-morbidities, it may or may not cause new health problems. The Q wave appears because the muscle can no longer transmit electrical signals through the heart. An EKG measures the electrical activity of the heart so that's how it looks.

What exactly is a borderline q-wave of ekg?

Dr. Mark Rasak
Cardiology 33 years experience
Probably nothing: Q waves of certain width and height on an EKG has been associated with an old heart attack. This hallmark is not very specific and if its boderline and no clinical history or no real cardiac risk factors , its probably a normal variant.
A 29-year-old member asked:

Can you explain the different components of ECG report?

Dr. David Revere
Specializes in Cardiology
A lot!: For a cardiologist, an EKG can give information about the rate, the rhythm, whether there are signs of a congenital abnormality, signs of a heart attach or blocked artery, the thickness of the heart muscle, previous heart attack, and more. In experienced hands, an EKG can tell an incredible amount of information.

No problem: The leads are not placed on the breasts but on the chest wall. The breasts may overlap some of the leads, but they should stick just fine, otherwise.
