Relative Effectiveness of the Implantable Cardioverter-Defibrillator and Antiarrhythmic Drugs in Patients With Varying Degrees of Left Ventricular Dysfunction Who Have Survived Malignant Ventricular Arrhythmias

چکیده
RESULTS In patients with an LVEF $0.35, there was no difference in survival between AAD-treated and ICD-treated patients. A test for interaction was not significant, but had low power to detect an interaction. For patients with an LVEF 0.20 to 0.34, there was a significantly improved survival with ICD as compared with AAD therapy. In the smaller subgroup with an LVEF ,0.20, the same magnitude of survival difference was seen as that in the 0.20 to 0.34 LVEF subgroup, but the difference did not reach statistical significance.

Background: Dextrocardia is a congenital anomaly, which may have coexistent coronary artery disease (CAD), arrhythmias and conventional indications for device therapy. However, the implantation of transvenous leads can be technically challenging and the approach needs to be tailored to the patient's individual anatomy. Case presentation: A 54-year-old male with dextrocardia situs inversus and i...

The implantable cardioverter defibrillator (ICD) has had an enormous impact on the treatment of patients with lifethreatening ventricular arrhythmias. It has been shown not only to be effective in reducing mortality in patients who have survived a potentially life-threatening ventricular arrhythmia (1) but also to improve outcomes when used as primary prevention for sudden cardiac death in pati...

BACKGROUND Patients with left ventricular ejection fraction (LVEF) ≤ 35% are eligible for implantable cardioverter-defibrillator (ICD) placement for the primary prevention of sudden cardiac death (SCD). This recommendation results in continuously growing waiting lists of patients who have been qualified for and are awaiting the procedure. Whiled reduced LVEF is a feature shared by all the patie...
متن کاملThe implantable cardioverter defibrillator.
Implantable cardioverter defibrillators (ICDs) have evolved from the treatment of last resort to the gold standard therapy for patients at high risk for ventricular tachyarrhythmias. High-risk patients include those who have survived life-threatening arrhythmias, and individuals with cardiac diseases who are at risk for such arrhythmias, but are symptomless. Use of an ICD will affect the patien...
متن کاملCardiac Arrhythmia 3 Ventricular arrhythmias and sudden cardiac death
Management strategies for ventricular arrhythmias are guided by the risk of sudden death and severity of symptoms. Patients with a substantial risk of sudden death usually need an implantable cardioverter defibrillator (ICD). Although ICDs effectively end most episodes of ventricular tachycardia or ventricular fibrillation and decrease mortality in specific populations of patients, they have in...
