Afib causes up to 20% of the 750,000 strokes that occur in the US annually, many of which are preventable through treatment with anticoagulants. Our objective is to increase detection of Afib prior to the occurrence of a stroke, allowing patients the opportunity to get treated for Afib and thereby reduce their stroke risk. The Propulse Afib Watch automatically checks the pulse rhythm once a day, every day and makes home screening for Afib easy.
