Are they really a temporary solution who cannot get an implantable cardiacdefibrillator (ICD)?
您认为,它们是否只是不能接受植入性心脏除颤器(ICD)的患者的权宜之计?

More sophisticated than a pacemaker, the gadget - called an ICD or implantable cardiacdefibrillator - is like a miniature, automatic version of the electric shock equipment used in emergencies.
If they are advanced in age they still are at risk of cardiac arrest but there are so many other things people die of their benefit from a defibrillator is questionable.
