Radiofrequency Catheter Ablation of Atrioventricular Nodal Reentry Tachycardia
coronary sinus selectively affect slow pathway function. The current study compares the safety, efficacy, and electrophysiological effects of these two techniques in a prospective, randomized fashion. Methods and Results. Fifty consecutive patients with typical AVNRT were randomly assigned to receive radiofrequency lesions either anteriorly (n=22) or posteriorly (n=28). If the initial approach ...
متن کاملMultiple anterograde atrioventricular node pathways in patients with atrioventricular node reentrant tachycardia.
OBJECTIVES This study sought to investigate electrophysiologic characteristics and possible anatomic sites of multiple anterograde slow atrioventricular (AV) node pathways and to compare these findings with those in dual anterograde AV node pathways. BACKGROUND Although multiple anterograde AV node pathways have been demonstrated by the presence of multiple discontinuities in the AV node cond...
متن کاملCatheter modification of the atrioventricular junction with radiofrequency energy for control of atrioventricular nodal reentry tachycardia.
BACKGROUND The utility of transcatheter application of radiofrequency energy to eliminate atrioventricular nodal reentrant tachycardia (AVNRT) was investigated. METHODS AND RESULTS Thirty-nine patients (mean age, 53 +/- 20 years; range 14-86 years) with medically refractory AVNRT underwent perinodal ablation with radiofrequency energy. A custom-designed 6F catheter with a large (3-mm-long) di...
متن کاملRadiofrequency Catheter Ablation Of Atrioventricular Nodal Reentry Tachycardia In A Patient With Inferior Vena Cava Anomaly
Curative radiofrequency catheter modification of the slow pathway is the recommended therapy for patients suffering from recurrent symptomatic atrioventricular nodal reentry tachycardia. This is usually performed via femoral vein and the inferior vena cava (IVC). Presence of venous occlusion or complex venous anomaly involving the IVC may preclude this approach. Here, we report a case with a co...
متن کاملVariation of P-QRS relation during atrioventricular node reentry tachycardia.
OBJECTIVES The main objective of this study was to characterize the phenomenon of variation in the P-QRS relation during atrioventricular node reentry tachycardia. BACKGROUND Variation of P-QRS relation during tachycardia has been observed occasionally in atrioventricular node reentry tachycardia. However, the incidence, the characteristics and the mechanisms of this phenomenon have not been ...
