On September 28,the FDA approved the first subcutaneous ICD SCD for ventricular tachyarrhythmias which allows the lead to be placed under the skin rather than through a vein into the heart.Miller; Cleveland Clinic Foundation, Cleveland: Analyses are presented as the adjusted average change from base line in each study group. Patients were unaware of the pacing assignment. The vast majority of investigational studies have quantified left ventricular systolic function using the measure of left ventricular ejection fraction LVEF. The patients enrolled at 91 clinical sites had a median follow-up of
Implantable pacemaker for the heart. Be sure you have a hand-held magnet to test your device daily by placing the magnet over the device daily to assure angeschaltet audible tone lasting approximately 20 seconds occurs. In both the PASE trial and our study, about 75 percent of crossovers occurred within six months. Prespecified Subgroups There were no statistically significant differences in the risk of death, stroke, and hospitalization for heart failure between the two treatment groups among patients over 75 years of age, women, nonwhite patients, or patients with a history of supraventricular tachycardia Figure 2 Figure 2 Unadjusted Subgroup Comparisons According to the Mode of Pacing. This is likely due to the fact that death in the first 40 days post-MI may be attributed to causes other than arrhythmia. Since mode changes are easier with this design, we may have overestimated the true incidence of the pacemaker syndrome and reduced the number of clinical events in the ventricular-pacing group. Martin; Lankenau Hospital, Wynnewood, Pa.: Enrolled patients were randomized to either ICD implantation or to therapy considered appropriate by the treating physician. Over 50 percent of patients had a history of supraventricular tachycardia, generally atrial fibrillation or flutter that had occurred within the past three weeks. With antitachycardia pacing, the device delivers a preset number of rapid pulses in succession in an attempt to terminate the ventricular tachycardia.
