Long-term ventricular pacing in treatment of sinoatrial block.
نویسنده
چکیده
Six patients with symptoms due to sinoatrial block are described in whom no relief or improvement in block occurred when they were treated with isoprenaline or ephedrine. All six patients were treated by ventricular cardiac pacing with complete relief of symptoms. Despite the theoretical disadvantages of parasystole and loss of accrochage in treating these patients by ventricular pacing they have survived for periods of 18 months to over five years.

Closed loop stimulation improves ejection fraction in pediatric patients with pacemaker and ventricular dysfunction.
BACKGROUND The aim of this prospective study was to evaluate the effect of the closed loop stimulation (CLS) on the ejection fraction in pediatric patients, affected by complete atrioventricular block (CAVB) or CAVB and sinus node dysfunction (SND), with a previously implanted pacemaker (PM) and ventricular dysfunction. The role of electrical therapy in the treatment of pediatric patients with ...

H eart failure effects 1–2% of the population and accounts for approximately 5% of all medical admissions; despite the undoubted improvements in treatment over the past two decades, the outcome remains poor. One third of those patients admitted with decompensated heart failure die within one year of their first hospitalisation and up to 50% will be readmitted within the first six months after t...
متن کاملPostoperative Arrhythmias after Cardiac Surgery: Incidence, Risk Factors, and Therapeutic Management
Arrhythmias are a known complication after cardiac surgery and represent a major cause of morbidity, increased length of hospital stay, and economic costs. However, little is known about incidence, risk factors, and treatment of early postoperative arrhythmias. Both tachyarrhythmias and bradyarrhythmias can present in the postoperative period. In this setting, atrial fibrillation is the most co...
متن کاملIdiopathic sustained left ventricular tachycardia: clinical and electrophysiologic characteristics.
Electrophysiologic studies were performed in 16 patients 11 to 45 years old (mean 33 years) with idiopathic sustained (lasting more than 5 min) ventricular tachycardia (VT) originating from the left ventricle. Endocardial mapping during VT showed that the earliest site of activation was at the apical inferior portion of the left ventricle in 14 patients whose QRS morphology during VT showed a r...
متن کاملLong‐Term Impact of Right Ventricular Pacing on Left Ventricular Systolic Function in Pacemaker Recipients With Preserved Ejection Fraction: Results From a Large Single‐Center Registry
BACKGROUND There is limited evidence of long-term impact of right ventricular pacing on left ventricular (LV) systolic function in pacemaker recipients with preserved LV ejection fraction (LVEF). The objective of the study was to evaluate the outcome and echocardiographic course of baseline preserved LVEF in a large cohort of pacemaker recipients with respect to pacing indication and degree of ...
