People in Wales who are at risk of their heart stopping suddenly, may be fitted with wearable defibrillators following new guidance by Health Technology Wales.

Wearable cardioverter-defibrillators continuously monitor heart rhythm and automatically deliver an electric shock within one minute, when certain irregular heart rhythms are detected.

They are worn like a vest as an interim measure and should only be taken off when the wearer is bathing.

Patients can take them home meaning they do not need to stay in hospital during a recovery period, while waiting for medication to work or for the fitting of an implantable cardioverter defibrillator (ICD).

Health Technology Wales looked for evidence on the effectiveness and cost effectiveness of wearable cardioverter-defibrillators and has published guidance recommending the adoption of the device for some, but not all adult patients who are at high risk of sudden cardiac death in Wales.
