BACKGROUND Supraventricular arrhythmia (SVA) is a frequent clinical complication in adult patients with congenital heart disease (CHD). The aim of this study is prognostic evaluation of congenital heart defect complexity, performed cardiac surgery, initial functional impairment of the heart - NYHA > I, cyanosis, age and sex of the adult patients with CHD, presenting for the first time to an out...

Objective: From January 1998 to February 1999, 160 patients undergoing lung resection for non-small cell lung cancer were studied to de®ne factors that increase the risk of postoperative supraventricular arrhythmia (SA) and to assess the effectiveness of amiodarone as an antiarrhythmic drug. Methods: All patients were monitored intraoperatively and postoperatively up to day 3. Onset of SA was d...

AIMS Although arrhythmia surgery and radiofrequency catheter ablation to cure atrioventricular nodal reentrant tachycardia differ in technical concept, the late results of both methods, in terms of elimination of the arrhythmogenic substrate and procedure-related new and different arrhythmias, have never been compared. This constituted the purpose of this prospective follow-up study. METHODS ...

was effective for controlling 64% of patients, with partial control achieved in an additional 13%. The incidence of side effects necessitating drug withdrawal was 15%. In the study of Hammill et al, most patients (60%) had no significant cardiovascular disease, while 74% of Kerr’s group had primary AF without associated heart disease. We had a lower success rate than these 2 previous groups, bu...

A prospective study of 50 consecutive patients undergoing cardiac valve replacement was designed to determiine the incidenice, types, and predisposing factors to postoperative arrhythmias. Patients were monitored continuously for the first 7 days following surgery. Thirty-seven patients (74%) experienced a total of 66 episodes of arrhythmia. Supraventricular arrhythmias were the most common (43...

This paper proposes the fractal patterns classifier for multiple cardiac arrhythmias on field-programmable gate array (FPGA) device. Fractal dimension transformation (FDT) is employed to adjoin the fractal features of QRS-complex, including the supraventricular ectopic beat, bundle branch ectopic beat, and ventricular ectopic beat. FDT with fractal dimension (FD) is addressed for constructing v...

Introduction Junctional ectopic tachycardia (JET) is a rare type of supraventricular arrhythmia. Even if its management has improved in recent years, it remains a great challenge for the cardiologist. Two are the possible clinical presentations of this arrhythmia: as a primary idiopathic disorder during infancy, configuring the so called "congenital" JET, or more often as a transient phenomenon...

The normal fetal heart shows variation in rate and rhythm. Twenty three cases that fell outside the normal patterns of variation of heart rate and rhythm were evaluated by echocardiography. Ten showed atrial or ventricular extrasystoles and these were not associated with perinatal morbidity or mortality. Seven cases showed complete heart block, two in association with structural cardiac abnorma...

This paper presents an effective arrhythmia classification algorithm using the heart rate variability (HRV) signal. The proposed method is based on the Generalized Discriminant Analysis (GDA) feature reduction technique and the Multilayer Perceptron (MLP) neural network classifier. At first, nine linear and nonlinear features are extracted from the HRV signals and then these features are reduce...

INTRODUCTION Over the past decade, several advances have been made in the management of tachycardias by pacing techniques, but limited data are available on the long-term outcome of patients treated with antitachycardia pacemakers. PATIENTS AND METHODS An antitachycardia pacemaker, the Intermedics Intertach, was implanted in 22 (17 female) patients with supraventricular tachycardia over a fiv...
