Site of reentry in paroxysmal supraventricular tachycardia in man.
a portion of the relative refractory period of the A-V node consistently produced atrial reentry-echoes or sustained SVT. In two patients, APDs falling within the A-V effective refractory period failed to excite the His bundle but still reentered within the A-V node and began SVT. It was noted that the various relationships between atrial and ventricular depolarizations on the surface ECG did n...

متن کاملMalignant Paroxysmal Supraventricular Tachycardia
A 63 year old male had a sudden episode of cardiac arrest during travel. He was resuscitated and cardioverted successfully with a semi-automatic defibrillator. The first ECG showed atrial fibrillation with inferior Q waves and he spontaneously reverted to sinus rhythm over the next few hours. The patient had been asymptomatic up to the episode of cardiac arrest and referred no prior history of ...

mg, mean ± SD) of disopyramide for three to five doses over 24 hours and were then restudied. All patients had inducible, sustained PSVT during the control study. After disopyramide, PSVT was noninducible in eight patients (50%), including six of nine with atrioventricular nodal reentrance and two of seven with atrioventricular reentrance; inducible but nonsustained in two (12.5%) (both with at...
متن کاملCircadian variation of paroxysmal supraventricular tachycardia.
BACKGROUND Various clinical manifestations of cardiovascular diseases have a pattern of circadian variation. In this study, we investigated whether the onset and duration of paroxysmal supraventricular tachycardia (PSVT) has a circadian variation. METHODS AND RESULTS In our analysis, we included 105 patients with 498 PSVT episodes. In this study, the onset of PSVT did not have a uniform distr...
