Physician Prescriptions for ZOLL LifeVest Top 20,000

Zoll Medical Corporation (NasdaqGS: ZOLL) announced today that more than 20,000 patients at high risk of sudden cardiac arrest (SCA) have been prescribed the LifeVest^® Wearable Defibrillator by their physicians.

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 patients’ physician time to assess their 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.

"We have witnessed phenomenal growth of the LifeVest over the last three years, with over 2,900 physicians now prescribing the product and hundreds of lives having been saved. We believe it is also a significant milestone that the LifeVest has been prescribed by physicians at all the nation’s top cardiac hospitals as named in U.S. News and World Report,” stated Richard A. Packer, Chairman and Chief Executive Officer of ZOLL.

The LifeVest is used for a wide range of indications, 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.
