New Defibrillator Study Is Raising Worries
I read the study's abstract. I understand the results are referring to patients with heart failure only and not to people who are suffering from sudden arrhythmia death syndromes, but have a healthy heart otherwise.
Ironically, the September 2008 issue of the NEJM published another study** saying that in patients "with moderately symptomatic heart failure, single-lead ICD therapy was not associated with any detectable adverse quality-of-life effects during 30 months of follow-up".
