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 ...

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 ...

The ventricular rate is regular at 60 beats per minute (bpm) with narrow QRS complexes. There are typical atrial flutter waves at slightly greater than 300 bpm producing a “sawtooth” baseline pattern ...

Saint-Etienne, France - Radiofrequency ablation is more effective than treatment with amiodarone for the prevention of atrial flutter recurrence in patients who experienced a first symptomatic episode ...
