PHYSICIAN PRESCRIPTIONS FOR ZOLL LIFEVEST TOP 40,000   

LifeVest Wearable Defibrillator Prescribed by Physicians atAll U.S. News and World Report’s #1 Ranked “Top Metro” Hospitals

May 12, 2011─CHELMSFORD, MASS.–ZOLL Medical Corporation (Nasdaq GS: ZOLL) announced today that more than 40,000 patients at high risk of sudden cardiac arrest (SCA) have been prescribed the LifeVest® Wearable Defibrillator. It was also reported that physicians at all of the “Top Metro” hospitals designated by U.S. News and World Report as the number one hospital in each of 52 metropolitan areas have prescribed the LifeVest for patients.

The LifeVest is worn by patients at risk for SCA, providing protection during their changing condition and while permanent risk for SCA 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. If a life-threatening heart rhythm is detected, the device delivers a treatment shock to restore normal heart rhythm.

“The fact that these two significant milestones occurred simultaneously indicates the growing adoption of the LifeVest by leading physicians in their treatment protocol for patients at risk of SCA,” said Richard A. Packer, Chief Executive Officer of ZOLL.

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.
