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

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

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

Left atrial enlargement , R-axis -57 Abnormal ECG ?

Left atrial enlargement , R-axis -57
Abnormal ECG

?

ECG: Without seeing the ecg and only given what you wrote, it isn't possible to know whether the ecg is abnormal or not. An axis of 57 degrees is not a 'right axis', 157 degrees would be. Left atrial enlargement has definite ecg parameters but doesn't always mean significant abnormality is present. If it were possible to see the ecg more comment would be possible. ...Read more
