Paroxysmal Supraventricular Tachycardia: A Complex Dilemma during Pregnancy

Outcomes Associated With Paroxysmal Supraventricular Tachycardia During Pregnancy.

Paroxysmal supraventricular tachycardia (PSVT) is the most common symptomatic arrhythmia during pregnancy.1 Although PSVT is usually considered transient and harmless, its association with maternal and fetal outcomes during pregnancy are unknown.2–4 In this study, we used a national population cohort to measure the associations between PSVT events during pregnancy and maternal or fetal outcomes...

Malignant 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 ...

Induction of Paroxysmal Supraventricular Tachycardia

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...

Significance of ST segment depression during paroxysmal supraventricular tachycardia.

During paroxysmal supraventricular tachycardia, patients frequently experience chest pain and marked ST segment depression suggesting acute myocardial ischemia. The purpose of this study was to assess whether ST depression during supraventricular tachycardia is caused by myocardial ischemia as reflected by net myocardial lactate production. Twenty-five patients (14 men, 11 women) who had a hist...
