Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

I just had a ecg and it said left axis deviation and a t wave abnormality. What does this mean?

I just had a ecg and it said left axis deviation and a t wave abnormality. What does this mean?

Understanding based: Both heart anatomy & how the electrical stimulation spreads from cell-to-cell with the atria, then within the ventricles. Both terms relate to both the anatomy & electrical activity within the ventricles, both depolarization (left axis deviation) and then repolarization (T waves). Depolarization is delayed toward right vs. Left side of ventricles. Repolarization pattern not normal; many reasons. ...Read more

I have just done a ecg and it came back with a left axis deviation and t wave abnormality. What does that mean?

I have just done a ecg and it came back with a left axis deviation and t wave abnormality. What does that mean?

Left axis deviation: What that means is the doctor who was "caring" for you has not been very pleasant or helpful. Two things to do: 1: Please have your doctor explain all of the information to you. There is absolutely no reason why that did not happen already. 2: You can go online and look for several patient centered articles that will be helpful. ...Read more

In SIMPLEST terms... can you explain ECG axis... what axis (left/right) deviation means...and how to spot it on ECG. Thanks?

In SIMPLEST terms... can you explain ECG axis... what axis (left/right) deviation means...and how to spot it on ECG. Thanks?

Electrical axis: Roughly corresponds to size & shape of heart. No simple answer. Can indicate left or right ventricular muscle enlargement, left or right atrial enlargement, dextrocardia, loss of activity by a portion of heart muscle. After you get your MD you can spend some time learning to interpret cardiograms. It is hard. Most Drs are not good at it. ...Read more

What does it mean when an ECG says borderline and extreme right superior axis deviation. Slight high lateral repolarization disturbance consider Ische?

EKG: Consider ischemia which is not enough blood getting to heart because of blocked arteries or an aortic stenosis or old heart attack. Would be good to know how old you are and what other problems you have to give better answer. Happy to do 2nd opinion now. ...Read more

Ecg report says normal sinus rhythm and. Left axis deviation anterior fasicular block. What does this mean?

Ecg report says normal sinus rhythm and. Left axis deviation anterior fasicular block. What does this mean?

Abnormal ECG: Left anterior fascicular block is a form of conduction abnormality that is usually silent -- it means only is seen in the ECG -- but it would be wise to have a complete physical and a stress test at your age. ...Read more

If your ECG says right axis deviation is this a hypertrophy of the right ventricle or dilatation? Or is both possible?

Neither or both: RAD occurs due to RV pressure or volume overload which can be acute or chronic. Long term pressure overload will eventually lead to RVH. Long term volume overload will eventually lead to dilation. But you can have RAD acutely with neither. An example of that is acute pulmonary embolism. ...Read more

I had a pre-surgical ecg. The result is like : normal sinus rhythm left axis deviation abnormal ecg what does it mean?

Axis: The preponderance of electrical activity of your heart is directed to the left of your body. This may mean your left ventricle is thickened (hypertrophy), or may be caused by a minor conduction delay (left anterior hemiblock). Neither of these are very serious, and will probably not delay your surgery. Ask your doc about your ekg findings. ...Read more

My father age 60 years ECG reports shows that left anterior fascicular block, abnormal left axis deviation, is it dangerous????

My father age 60 years ECG reports shows that left anterior fascicular block, abnormal left axis deviation, is it dangerous????

Ekg: These findings aren't serious. I would watch for palpitations, chest pain, shortness of breath with exertion as more serious signs of heart problems. see the doctor asap with any of those. Hope this helps. ...Read more

My mom's ECG reads as Sinus Bradycardia with a single abnormal conducted beat, Left Axis deviation. What does that mean? She is 54 years old.

My mom's ECG reads as Sinus Bradycardia with a single abnormal conducted beat, Left Axis deviation. What does that mean? She is 54 years old.

Rate <60 & Purkinje: fiber damage within endocardium. Any rate below 60 BPM is defined as bradycardia (not unhealthy). The abnormal conduction & LAD both occur as a result of damage to the Purkinje muscle fibers (look this up) within the endocardium of her heart muscle; nearly alway a result of atherosclerosis & heart attacks within the inner wall of the left ventricle-the portion most susceptible to ischemic damage. ...Read more

Please tell me my ecg I normal? Rate 77 PR 200 QRSD 85 QT 392 QTc 444 AXIS P 51 QRS -19 T 45

Please tell me my ecg I normal? Rate 77 PR 200 QRSD 85 QT 392 QTc 444 AXIS P 51 QRS -19 T 45

ECG: Those values are within normal limits, the appearance of the ecg other than these measurements isn't here so can't be certain there's nothing in the morphology of the ecg that isn't right. These measurements are ok. ...Read more

Agree: Machine only doing what it was programmed to do. A good 20% of people have borderline or abnormal ekg. Many related to variation in lead placement and may have no physiologic correlate. Ekg could and probably should say: no significant dysrhythmia, ectopy or morphologic change suggestive of underlying heart disease or ongoing ischemia. Please corellate clinically and review with prior ekg. ...Read more

In several ECG the machine have interpreted "horizontal axis" (ca. P 62°, QRS -13°, T 50°). What can be the cause?

ECG: This is the net direction of electrical flow and can be influenced by body habitus. Are you short and wide? Do you have a large belly? This pattern is not necessarily caused by heart problems and often as I mentioned is just related to the way you are shaped. It is often seen in pregnant women. ...Read more

Hello, in description of my resting ECG is written: semi-horizontal qrs axis. What does this mean? Is this finding ok or not? Thanks for answer.

Hello, in description of my resting ECG is written: semi-horizontal qrs axis. What does this mean? Is this finding ok or not? Thanks for answer.

Computer EKG reading: The computer interpretation of an ECG is merely calculations put into words. You need to discuss the ECG findings with your physician who ordered it. To be able to interpret an ECG you have to take into consideration a pts symptoms, age, past medical history, and the ecg. ...Read more

Rightward axis boderline ECG please explain?

ECG: We measure many kinds of things on ECG. Borderline findings generally are of little significance. You should ask your doc whether yours have any meaning or are no problem. ...Read more
