Under the terms of the agreement, ZOLL plans to supply a total of 185 E Series units for distribution to the north, central and west, and southeast regions of the Welsh Service.

ZOLL Medical said the contract, valued at $1.7m, is the largest order to date for the E Series in the UK.

WAST spokesperson said from the outset, they have been impressed with the impact the full-featured E Series offers in improving outcomes from sudden cardiac arrest.

"The 12-lead STEMI option gives us the ability to simultaneously share information with the ED so they are prepared when the patient arrives. And throughout our relationship with ZOLL, we’ve come to rely on them for excellent customer service," he said.
