Note. SD= standard deviation; AVNRT= atrioventricular nodal reentrant tachycardia; AVRT= atrioventricular reentrant tachycardia; ATACH= atrial tachycardia; IST= inappropriate sinus tachycardia; AFL= atrial flutter; SVT= supraventricular tachycardia; HR= ventricular heart rate; bpm: beats per minute; LVEF= left ventricular ejection fraction per transthoracic echocardiogram.
a
= AFL group significantly different from all others;
b
= AFL group different from AVNRT;
c
= AFL group different from AVNRT & AVRT;
d
= AFL group different from AVNRT, AVRT, & IST.
