A heart rhythm disorder in which the upper chambers of the heart (the atria) contract faster than the lower chambers (the ventricles) in an organized, predictable pattern. (In Atrial Fibrillation the atria beat chaotically and irregularly.)
a fast irregular rhythm in the atria
atrial flutter: a rhythm disorder originating in the heart's upper chambers that can cause rapid heart rates; may be treatable with radiofrequency ablation. What is catheter ablation? Catheter ablation, also known as radiofrequency (RF) ablation: a two-step procedure used to treat rhythm problems in the top or bottom parts of the heart. First, the area in the heart that causes the abnormal heart rhythm is located with the aid of a catheter. Next, the tissue in this area is "burned," thus interrupting the pathway that conducts the impulses that cause the abnormal rhythm.
A condition in which the upper chambers (atria) are contracting faster than the lower chambers (ventricles), causing a rapid, regular heart rhythm
a heartbeat disturbance, originating in the upper heart chambers -- the atria
An arrhythmia where the atria beat at a much higher than normal rate, though in a regular pattern.
A rapid well-organized contraction of the atrium at a rate of 250-350 contractions per minute. Ventricular beats are usually some multiple of 300. ECG shows saw tooth waves. Atrial flutter is considered a serious and potentially unstable rhythm.
Atrial flutter is similar to A Fib because it too is characterized by a rapid heartbeat. Instead of many disorganized signals, however, AFL is caused by a single electrical wave that circulates very rapidly in the atrium, about 300 times a minute, leading to a very fast, steady heartbeat.
a very fast beating of the atria (the upper two chambers of the heart).
A condition in which the upper chambers of the heart contract rapidly, but the heart rhythm is regular.
Well-organized but overly rapid contractions of the atrium of the heart (usually at a rate of 250-350 contractions per minute). See the entire definition of Atrial flutter
A cardiac arrhythmia in which the atrial contractions are rapid (230-380 per minute), but regular.
a type of arrhythmia where the upper chambers of the heart (atria) beat very fast, causing the walls of the lower chambers (ventricles) to beat inefficiently as well.
an abnormally fast but regular rhythm in the atria; typical atrial flutter is located in the right atrium and atypical flutter may occur in either.
Atrial flutter is a rapid atrial rhythm, usually at about 300 bpm, characterized by a 'sawtooth' waveform. It occurs due to one or two macroreentrant circuits within the atria.
an irregular heartbeat in which the upper chambers of the heart (the atria) beat rapidly but consistently
Atrial flutter is a rhythmic, fast rhythm that occurs in the atria of the heart. This rhythm occurs most often in individuals with organic heart disease (ie: pericarditis, coronary artery disease, and cardiomyopathy).
