Question 1

what do the letters qrs mean on the the electrocardiogram?

Accepted Answer

ECG QRS: Q is a downward deflection on the ecg, r is an upward deflection and s a downward one. The trio, qrs, represents the electrical activity ov ventricular contraction on the electrocardiogram.

Question 2

what does situs solitus and levocardio means on electrocardiogram?

Accepted Answer

Levocardia: Situs solitus means the abdominal organs are on the correct sides of the abdomen. Levocardia means the heart is on the left side which is where it is supposed to be. So basically it is saying everything is where it is supposed to be! Yeah!

Question 3

abnormal treadmill stress electrocardiogram at 9.1 mets, but not associated with significant echocardiographic changes.  what does this mean?

Accepted Answer

Stress echo: When ECG changes are not associated with echo wall motion abnormalities, there is a good chance the ECG changes are not related to ischemia.

Question 4

very good morning doctors! on an electrocardiogram, what do the following 2 things mean: qtc 439 ms and qt interval 419 ms? are these good or not good?

Accepted Answer

Within normal range.: The QT interval in the ECG is a measure of the duration of ventricular electrical activation and recovery. QTc refers to the same interval corrected for the heart rate at the time of recording. Inherited problems with the QT interval are commonly associated with rhythm problems as are the effects of electrolytes in the blood and medications. The QT shortens with increased heart rate and vice versa

Question 5

my ekg showed an abnormal precordial qrs contours, what does this mean?

Accepted Answer

: This is a very incomplete description or conclusion of an EKG interpretation. Precordial refers to the chest leads as opposed to the limb leads. QRS is the portion of the EKG during contraction of the heart muscle. The interpreting MD described its morphology as abnormal without further comment of what it could signify(such as scarred,enlargement of a ventricle,conduction disturbance, etc).

Question 6

my ecg showed an abnormal precordial qrs contours, what does this mean?

Accepted Answer

Do not worry about i: In a young person, I would not be worried unless you have some kind of congenital heard disease. Why did you have an ECG done in the first place???
We rarely do an ECG in your age group. Do you have any heart disease? Symptoms ? What led to doing an ECG is the first thing you need to tell us about your health???

Question 7

i've just got an ecg and it says something like this: high voltage qrs complexes on the pre-cordials derivations what does it mean ?

Accepted Answer

It could be : Normal or lvh.

Question 8

what is atypical ecg mean?

Accepted Answer

: That the pattern of the heart impulses are not what is considered normal. This can happen in disease and in a few without

Question 9

do ecg changes always mean mi?

Accepted Answer

No: No. There are multiple reasons why an EKG shows 'changes'. In fact, EKG is a measure of the electrical activity of the heart, and for this reason anything that influence this can cause ekg changes (electrolytes abnormalities, temperature, microvascular problem, disease of conduction sytem, etc..., as well as poor blood supply to the heart, such in the case of MI)

Question 10

what does this mean from a ekg?

Accepted Answer

More info: Your question does not include the ekg finding you are concerned about. Please resubmit your question with more information, and we will be glad to try to answer it.
