Electrophysiological characteristics and radiofrequency ablation of focal atrial tachycardia originating from the superior vena cava.
The initiation of focal atrial tachycardia (AT) from the superior vena cava (SVC) remains unclear. In 3 patients (2 females, 1 male; aged 57, 66 and 50 years, respectively) with focal AT arising from different parts of the SVC, the AT occurred spontaneously, rather than being induced by electrical stimulation. The cycle length of the tachycardia was highly variable, ranging between 190 and 300 ...
متن کاملFibrillation in the superior vena cava mimicking atrial tachycardia.
A 49-year-old male was referred for catheter ablation for paroxysmal atrial fibrillation (PAF). PAF had recurred after each of 2 prior left atrial ablation procedures. He had a structurally normal heart with a left atrial diameter of 43 mm. The patient presented to the electrophysiology laboratory in AF with an average AF cycle length (CL) of 150 ms and reconnected pulmonary veins. After electr...
متن کاملInitiation of atrial fibrillation by ectopic beats originating from the superior vena cava: electrophysiological characteristics and results of radiofrequency ablation.
BACKGROUND The superior vena cava (SVC) has cardiac musculature extending from the right atrium. However, no previous study in humans has given details regarding the ectopic foci that initiate paroxysmal atrial fibrillation (PAF), which may originate from the SVC. METHODS AND RESULTS A total of 130 patients with frequent attacks of PAF initiated by ectopic beats were included. Eight patients ...
متن کاملSuperior Vena Cava Isolation In Ablation Of Atrial Fibrillation.
Superior vena cava (SVC) is one of the most important non-pulmonary vein (PV) origins of atrial fibrillation (AF). SVC isolation (SVCI) is effective especially in patients with paroxysmal AF from SVC origin. However, SVCI should be carefully performed because of potential complications such as phrenic nerve paralysis, SVC stenosis, and sinus node injury There are two major different approaches ...
متن کاملComplicated atrial tachycardia due to atrial fibrillation originating from the superior vena cava
INTRODUCTION The superior vena cava (SVC) can act as an origin of atrial fibrillation (AF). The complex structure and special conductive properties of the SVC can result in complicated atrial tachycardia (AT), atrial flutter, or AF. SYMPTOMS AND CLINICAL FINDINGS We report a case of the clinical observation of various kinds of AT and AF in 1 patient. Electrophysiological (EP) studies confirme...
