A recent electrocardiogram revealed an enlarged left atrium. I'm only 25 but heart disease runs in my family. How serious of a condition is this?

Depends: There are 2 question: is the atrium truly enlarged and, if so, is there a reason for it: both can be answered with an echocardiogram. Usual reasons for left atrial enlargement are: hypertension, left ventricular diastolic dysfunction, atrial fibrillation, mitral valve disease, and atrial septal defect. The EKG is very indirect. The echo is much more accurate as it directly measures LA size. ...Read more

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

EKG says "Borderline ECG" and "probable left atrial enlargement." Is this anything of concern?

EKG says "Borderline ECG" and "probable left atrial  enlargement." Is this anything of concern?

I do not know: Your dr. who knows you best, will take that reading and compare it to your overall physical condition, and most likely it will be fine, but they need to discuss it with you to be sure. ...Read more

Atrial pairs, what are they and why do they show up on my ecg? Benign?

Atrial pairs, what are they and why do they show up on my ecg? Benign?

Irregular heart beat: Atrial pairs mean two irregular heart beats coming from the upper heart chambers occuring in pairs or following each other. It is benign and occurs in otherwise normal people ...Read more

What to do if I had an EKG well several that showed possible left and right atrial enlargement since then I have had bouts?

Echocardiogram: The EKG is not the swiftest way to diagnose this - you need an echo. Not only will it rule the problem in or out, it will provide information about why they're enlarged (if they are). ...Read more

Is borderline ECG with right atrial overload okay?

Ecg: Borderline ECG with right atrial overload pattern is a nonspecific finding. You should discuss with your doctor whether it has meaning in you. ...Read more

What segment of an ECG tracing represents the end of the atrial action potential?

What segment of an ECG tracing represents the end of the atrial action potential?

Ecg: The ecg represents the surface recording of electrical vectors produced by the summated electrical forces through time produced by the cells of the heart. As such there are millions of atrial action potentials summated in each portion. Roughly the end of the p wave and the rest of theQRS-T would correlate with atrial repolarization and depolarization would be present as the p wave appears ...Read more

Can you see an atrial repolarization wave/complex on an ecg/ekg?

Can you see an atrial repolarization wave/complex on an ecg/ekg?

Atrial repolarizatio: You can see this on some ecgs but not on most. It is seen when present after the P wave and before the onset of the QRS ...Read more

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

Does abnormal EKG mean I have atrial fibrilation?

EKG afib: An ekg can diagnose afib. There are many different abnormalities that can be seen. Abnormal does not equal a fib. ...Read more
