The recent news that Guidant defibrillators may malfunction during life critical moments has given heart patients pause. The highest rate of malfunction among Guidant machines is the Ventak Prizm 2 DR (Model 1861)with 28 reports of short-circuiting including one resulting in death. According to a story in today’s Wall St. Journal, physician reaction is mixed. The WSJ reported that prominent Indiana cardiologist Douglas Zipes believes it’s a matter of conscience. “I put the implanted defibrillator in the patient because the patient is at risk of sudden death. How can I in good conscience then not replace the device?” At this point, it’s important to check with your cardiologist if you have one of these implanted devices.
