RESUMEN

This study was performed on 40 patients for the evaluation of palpitations. There were 17 patients with inappropriate sinus tachycardia diagnosed with an elevated resting heart rate and an exaggerated heart rate response to exercise in the absence of organic illness, they were excluded from the study. The other 23 patients [16 females and 7 males] were diagnosed as paroxysmal unexplained palpitations. All patients had careful history taking, cardiac exam and baseline labs including complete blood count and thyroid functions. Also, they had regular 12-lead ECG, echocardiography, 24-Holter monitoring and exercise test. All patients underwent baseline electrophysiologic studies in a drug- free state of anti- arrhythmic medicine. Atrial and ventricular stimulation protocol using up to three extrastimuli was done as well as using Isuprel infusion if no tachycardia was induced at baseline. The study concluded that palpitation is a common symptom that needs a careful work-up to assess the etiological diagnosis. Electrophysiological studies in these patients have a low yield and should be only considered in patients with documented sustained arrhythmia or highly suspicious for rhythm disorder

RESUMEN

In this study, 11 patients affected by rheumatic mitral valve disease and chronic atrial fibrillation underwent mitral valve surgery and radiofrequency [RF] ablation. The mean duration of atrial fibrillation [AF] was 3.6 +/- 1.2 years. A control group [no RF] included 11 patients underwent mitral valve surgery only during the same period. RF endocardial ablation was performed under temperature control after left atriotomy. RF pulses were delivered in order to obtain a circumferential isolation of each pulmonary vein alone without any additional lines. Firstly, all patients received a loading dose of amiodarone in the early postoperative period, followed by a maintenance dose of 200 mg/day for three months. It was concluded that circumferential isolation of each pulmonary vein [PV] in patients with chronic AF undergoing mitral valve surgery is a feasible, safe and effective procedure in restoring sinus rhythm [SR] at an average follow-up period of six months
