ScienceTechyNews: Team studies smarter automatic defibrillator

Automatic implantable cardiac defibrillators (AICDs) deliver shocks to the heart to correct arrythmias. They do so based on electrocardiogram data. A team of researchers from UT Health San Antonio and UT Austin have now shown that an AICD can be programmed to also measure stroke volume -- the amount of blood pumped out of the heart. The hope is that this will enable the AICDs to deliver shocks only when needed.
