"The magnet mode is a feature of ICDs which allows emergency suppression of defibrillator therapy when a donut magnet is placed over the device ... With the removal of the magnet, tachycardia sensing and therapy are restored" [1] If this applies to all ICDs equally then the risk is limited to the time that the iPad2 remains on their chest (e.g snoozing, reading in bed, etc). I think projects like this are cool. If there was a 30% chance of a relative's pacemaker being affected by an external device, I'd think twice about buying them said device.
