Medtronic follows St Jude in making V-V (ventricle-to-ventricle) upgrades for CRT (cardiac resynchronisation therapy)

The US FDA has given Medtronic the all-clear to include a ventricle-to-ventricle (V-V) timing feature in its cardiac resynchronisation therapy (CRT) defibrillators for treating heart failure, making it the second firm behind St Jude Medical late last year to have gained such an approval. In addition, the agency has granted St Jude permission to make V-V timing available in all its Epic and Atlas CRT defibrillators; the feature had previously been available only in certain models of the devices.
