Fatal episodes of VFib require an AICD implant
Body
DEAR DR. ROACH: I’m an 88-year-old female who has been diagnosed with ventricular fibrillation (VFib). My cardiac electrophysiologist, who implanted a conventional pacemaker four years ago, has noticed several episodes of VFib (up to 30 seconds, read via a bedside monitor). They recommend replacing the current pacemaker with a combo pacemaker and defibrillator. I wonder about the history/success of this device. -- C.R.
