Two amazing Eucharistic miracles show the Host pulsating in the rhythm of a human heart with contraction and relaxation phases, systole (the contraction phase) and diastole (the relaxation phase). 

The first mirace: A pilgrim from New Jersey caught on film a Eucharistic miracle that occurred in Venezuela, 1998, in a convent in Los Teques. The Same Host Shed Blood in 1991 The second: The video was captured on July 22 at Our Lady of the Rosary parish in Zapotlanejo, a town in the Mexican state of Jalisco, during Eucharistic exposition.
