Why everyone with Afib should have an echocardiogram

An echocardiogram is an ultrasound-based assessment of the heart.  It is painless, harmless, readily available in most hospitals and can give a large amount of very useful information about the structure and function of the heart.  As atrial fibrillation can be caused by a structural problem with the heart such as heart valve disease or heart muscle weakness, the echo can help to elucidate the und [...]

Atrial Flutter?

What is atrial flutter? Atrial flutter is an abnormal heart rhythm. In atrial flutter, the atria contract at 300 beats per minute and every other impulse goes down into the ventricles and therefore the ventricles beat at 150 beats per minute. In patients who are taking medications such as beta blockers or calcium blockers the impulses reaching the ventricles may be reduced even more so the heart r [...]
