Guidant Pacemakers

Guidant Corp. warned physicians that the hermetic sealing component in its implantable pacemakers may break down over time and cause serious health problems.

Pacemaker brands involved are Pulsar, Pulsar Max, Intelis II, Discovery, Pulsar Max II, Meridian, Discovery II, Virtus Plus II  and Contak TR. Guidant advises that doctors consider replacing the devices in people dependent on pacemakers, while patients noticing dizziness, shortness of breath, fast heart rate or lightheadedness should seek medical attention.
