PHYSICIAN PRESCRIPTIONS FOR ZOLL LIFEVEST TOP 25,000

Wearable Defibrillator Continues to Gain Acceptance as Standard of Care

May 18, 2010CHELMSFORD, MASS.–ZOLL Medical Corporation (Nasdaq GS: ZOLL), a manufacturer of medical devices and related software solutions, announced today that more than 25,000 patients at 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/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 the LifeVest has been prescribed by physicians to more than 25,000 patients is a tangible measure of the important role this treatment option plays in the standard of care for patients at risk of SCA,” stated Richard A. Packer, Chairman and Chief Executive Officer of ZOLL.  “We value the trust our physician customers place in our service and respect the important work of protecting patients at risk of SCA.”

“I believe it is also significant to note that LifeVest focused scientific publications and presentations have more than doubled over the last year, further demonstrating the ever-growing clinical engagement with the therapy,” Mr. Packer added.

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.
