Medtronic has [recalled](https://www.accessdata.fda.gov/scripts/ires/?Event=90565&ref=fdaweb.com) (Class 1) its Cobalt and Crome implantable cardioverter defibrillators because the devices have the potential for reduced shock energy (about 79% of programmed energy) during high-voltage therapy. The company says it has issued a software release to update the Cobalt and Crome implantable cardioverter defibrillators and cardiac resynchronization therapy defibrillators to “prevent the potential for an intermittent, second-phase Short Circuit Protection (SCP) event during high-voltage (HV) therapy delivery,” according to a Medtronic [field alert](http://file///C:/Users/dave/Downloads/15321-22%5Fkundeninfo%5Fen.pdf%3bjsessionid=84B1034198D7351C5760248A53E32B97.pdf?ref=fdaweb.com). The devices are used to provide pacing for slow heart rhythms, and electrical shock or pacing to stop dangerously fast heart rhythms.
