Spontaneous occurrence of symptomatic paroxysmal atrial fibrillation and paroxysmal supraventricular tachycardia in untreated patients.
BACKGROUND Ambulatory outpatients (n = 150) with a history of paroxysmal supraventricular arrhythmia were studied to establish the characteristics of the first recurrence of symptomatic tachycardia (time to first recurrence, heart rate during tachycardia, and observed rhythm that was regular versus irregular) when no antiarrhythmic drug was being taken. Baseline variables were examined to asses...
متن کاملCircadian occurrence of symptomatic paroxysmal supraventricular tachycardia in untreated patients.
Fifty-two patients with paroxysmal supraventricular tachycardia were studied to determine whether there was a circadian pattern to the occurrence of this arrhythmia. Antiarrhythmic therapy was discontinued, and patients were followed until they had one recurrence of tachycardia documented by telephone transmission of the electrocardiogram. By least-squares analysis, the times of day that the 52...

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...
