Atrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the atrial ...

Not all atrial ... ECG, the flutter waves are more apparent. The atrial rate is organized at a rate of about 300 beats per minute. The P waves are negatively deflected in the inferior leads ...

As noted above, the precordial leads are unreliable, compromising by their inclusion calculations deriving from the set of 12 ECG leads. It appears, therefore, that using sums of data from the six ...

CV evaluation included history, PE, 12-lead and exercise ECG, echocardiography ... or supraventricular tachyarrhythmias (atrial flutter, paroxysmal atrial fibrillation or SVT) were identified in 9 ...
