Question 1

what is borderline inferior q wave mean?

Accepted Answer

Q waves: There are criteria for significant depth and duration of Q waves for them to be signficant. Borderline means depth/width or both not quite significant.

Question 2

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

Accepted Answer

See answer.: A non Q wave myocardial infarction is an electrocariographic phenomenon. It usually implies a heart attack with less extensive damage than a Q wave one which implies damage from the inner wall to the outer wall of the heart. The findings on the electrocardiogram can be variable and must be correlated with the patient's symptoms and blood tests which confirm damage to the heart muscle.

Question 3

what does a q wave on a stress test represent?

Accepted Answer

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.

Question 4

what does a q wave mean on a ekg?

Accepted Answer

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.

Question 5

what exactly is a borderline q-wave of ekg?

Accepted Answer

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.

Question 6

what is an unrecognized non-q-wave myocardial infarction?

Accepted Answer

Two types of mi: One type is st  segment  elevation (formally called Q wave mi ) and a non st segment (formally called non q ) mi . The difference between the two is the ekg. St segment on the ekg and an elevated blood level of cardiac enzymes is usually obvious. In the non st segment mi the ekg may be normal or mildly abnormal. The enzymes come back elevated but usually aft  admission and a couple of blood sample.

Question 7

is a small q wave on an ecg significant?

Accepted Answer

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.

Question 8

what is a q wave in old heart attack?

Accepted Answer

Q waves suggest: Old myocardial infarction....This can be confirmed by echocardiogram.

Question 9

does q wave always mean you had a heart attack?

Accepted Answer

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.

Question 10

what is the significance of a non q wave heart attack?

Accepted Answer

EKG finding: A Q wave is a finding on the electrocardiogram seen after a completed myocardial infarction (heart attack).  In some patients with heart attack, the electrocardiogram will demonstrated q-wave.  In other patients, a Q wave will not develop.  In general, Q wave myocardial infarctions are larger and associated with st elevation in the early phase of the heart attack.
