new studies have shown that when it comes to heart patients men are 2 to 3 times more likely than are women to choose an implantable defibrillator to help keep their hearts beating regularly A new study finds that out of heart patients men are 2 to 3 times more likely to opt for implantable defibrillators than are women The devices are like mini pacemakers and can detect an
