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

What is the ECG finding for an atrial fibrillation and atrial flutter?

What is the ECG finding for an atrial fibrillation and atrial flutter?

This: In atrial fibrillation, there are no p waves seen, or the p waves are highly irregular and not directly correlated with the qrs complexes. In atrial flutter constant, regularized activity is seen, generally without a fixed baseline. ...Read more

I have atrial fibrillation but the blood work and ECG are normal. How is that?

I have atrial fibrillation but the blood work and ECG are normal. How is that?

Fleeting AF: Many people are not in atrial fibrillation continuously but, rather, on and off. An ECG is a 12 second strip - you may have been in an "off" period (in normal rhythm) during the ECG recording. Blood work is usually not affected in atrial fibrillation. ...Read more

Can innapropriate sinus tachycardia lead to atrial fibrillation got to go to hospital monday for ECG my heart rhythm gone from normal to abnormal?

Not usually: This would be a bit odd. Usually fibrillation is the result of age, drinking, and diseases which exhaust or stretch out the atria. Inappropriate sinus tach usually doesn't directly result in afib. When it went to "abnormal" are you sure that was to fib? Did they get an ekg? Could well be flutter too, which can occasionally be mistaken for fib. ...Read more

If I had atrial fibrillation would it have shown up on my ekg and stress tests?

If I had atrial fibrillation would it have shown up on my ekg and stress tests?

Depends: It depends if you have Afib all the time or intermittently. Would only show up on EKG and stress tests IF it was present at the time. If you have intermittent Afib there are simple tests that can show how often it is present and how Kong it lasts. Some people can always or sometimes feel it's presence, while others are totally unaware of when it occurs. ...Read more

Would atrial fibrillation show up on an EKG or is a holter monitor needed to diagnosis? I am convinced I have af but my EKG was normal.

Would atrial fibrillation show up on an EKG or is a holter monitor needed to diagnosis? I am convinced I have af but my EKG was normal.

It depends....: Atrial fibrillation is an abnormal heart rhythm which occurs mostly in the elderly. It can be persistent or paroxysmal (intermittent). An ECG shows the heart rhythm at the time it is being done. An abnormal rhythm would be seen only if the heart was in that rhythm at that time. A holter monitor would follow the rhythm over a period of time >24hrs and could show if it happens intermittently. ...Read more

In a fit, healthy 18 year old. Whats the worst that could happen if I have atrial fibrillation? Normal echocardiogram,ekg,but didn't have palps during

Nothing: Other than the sensation of palpitation ,atrial fibrillation in young healthy persons are benign. Since in this age group the arrhythmia is often associated with a very rapid heart rate they often require treatment to control heart beat or intervention to convert them back to regular rhythm ...Read more

How dangerous could atrial fibrillation be in a healthy, very fit 18 year old with no other problems? Normal echocardiogram, ekg, and stress test

Not likely: Atrial fibrillation is not as common in young individuals as in elderly. Sometimes benign arrhythmias are over diagnosed as atrial fibrillation. In your case how was your atrial fibrillation diagnosed? Otherwise atrial fibrillation remains a significant medical condition with a variety of possible complications, the most common being stroke. ...Read more

Atrial Fibrillation (Definition)

Atrial fibrillation is an irregular and often rapid heart rate that commonly causes poor blood flow to the body. During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly — out of coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation symptoms include heart palpitations, shortness ...Read more
