When your electrical system is working normally, the two upper chambers of the heart (atria) contract and pump blood into the two lower chambers (ventricles) in a well-coordinated way. This results in ...

MANY common arrhythmias observed in both atria and ventricles are similar although the atrial types have a few important distinguishing features. Thus, so far as therapy is concerned, the atrial ...

Not all atrial flutters demonstrate the typical "sawtooth" pattern. During the times of lesser conduction on this ECG, the flutter waves are more apparent. The atrial rate is organized at a rate of ...
