"The diagnosis of supraventricular tachycardia can be established using M-mode echocardiography, which may demonstrate paroxysms of atrial tachycardia in the range of 230 - 280 beats per minute (BPM), often following an extra-systole. M-mode echocardiography uses a sampling line placed across atrial and ventricular walls and times electromechanical events in the fetal cardiac cycle. However, it is often not possible to completely identify its precise electropathophysiologic mechanism by this method."
"Treatment and prognosis "
"It has a typical ventricular rate of 230-280 beats per minute (bpm) 1 and isoften associated with an accessory AV conduction pathway. There is a 1-to-1 atrioventricular conduction. A supraventricular tachycardia is only rarely associated with intra- or extra-cardiac anomalies (in contrast to other tachyarrhythmias)."
