HeartSine Technologies is recalling some of its samaritan® Automatic External Defibrillators. The affected devices may shut down before delivering a shock, which could delay treatment or even lead to death of a viable patient. We've received several user complaints that the device shut down during an attempted charge, but no injuries have been reported to date. This recall includes models SAM-001, SAM-002, and SAM-003 with certain serial numbers within the range of 1270 - 2324. The HeartSine samaritan® PAD automatic external defibrillator is not affected by this recall. HeartSine Technologies notified its distributors and customers by letter on February 14, 2005, and the company is providing a software upgrade for the affected devices. If you have a device within this serial number range, but have not yet received an upgrade kit, you should contact the company as soon as possible to see if your product is affected and to get the kit.
