Cryotherapy Versus Radiofrequency Ablation for Treatment of Para-hisian Accessory Pathways
Cardiac ArrhythmiasAccessory Pathway1 moreA randomized pilot study to evaluate safety and efficacy endpoints for treatment of para-hisian accessory pathways according to two different strategies of lesion formation. These patients will be divided into 2 groups with different strategies of treatment: group 1 treated with radiofrequency (RF) ablation, group 2 with cryotherapy (CRYO). The primary outcome will be the recurrence rate of accessory pathway conduction after one year of follow-up. Secondary endpoints will be immediate success and rate of permanent atrioventricular (AV) block.
Routine Mini-invasive Electrophysiology Study for Patients Feeling Tachycardia, With a Negative...
Pre-excitation SyndromesParoxysmal Tachycardia3 morePatients complaining of tachycardia but with a negative Holter ECG, are for a limited time period offered a simplified electrophysiological(EP) examination. By a full electrophysiological study(EP study)electrodes are introduced for pacing and sensing i all four heart chambers. Where as by the mini invasive EP study only one electrode is introduced to the right atrium. The simplified procedure represent a smaller risk of complications, requires less resources but should yield the same diagnoses in more than 90% of the cases. The study is a feasibility study to see if the procedure can discover arrythmias in a fairly unselected patient population.
Accessory Pathway Antegrade Effective Refractory Period Among WPW Patients: the Risk in Relation...
Wolff-Parkinson-White SyndromeTo correlate the antegrade effective refractory period of the accessory pathway with its anatomical location in the heart. To investigate whether the accessory pathway location can predict the high risk nature of the accessory pathway
