ZOLL Medical Corporation (NASDAQ GS: ZOLL), a manufacturer of medical devices and related software solutions, announced today that more than 60,000 patients at high risk of sudden cardiac arrest (SCA) have been prescribed the LifeVest® Wearable Defibrillator. The LifeVest is worn by patients at risk for SCA, providing protection during their changing condition and while permanent SCA risk has not been established. The LifeVest allows a patient’s physician time to assess his or her long-term arrhythmic risk and make appropriate plans. The LifeVest is lightweight and easy to wear, allowing patients to return to their activities of daily living, while having the peace of mind that they are protected from SCA. The LifeVest continuously monitors the patient’s heart and, if a life-threatening heart rhythm is detected, the device delivers a treatment shock to restore normal heart rhythm. “The fact that over 60,000 patients have been prescribed the LifeVest by their physicians demonstrates the ever increasing adoption of this therapy as part of the treatment protocol to protect patients at risk of SCA,” said Richard A. Packer, Chief Executive Office of ZOLL. “The powerful result of partnering with physicians to protect so many patients from SCA is that the life of more than one patient per day is being saved worldwide by a ZOLL LifeVest.” The LifeVest is used for a wide range of patient conditions or situations, including following a heart attack, before or after bypass surgery or stent placement, as well as for those with cardiomyopathy or congestive heart failure that places them at particular risk. The LifeVest is covered by most health plans in the United States, including commercial, state, and federal plans. For more information, go to www.zoll.com or call 1-800-543-3267.
