Details, from Catholic News Agency: 

A video circulating on social media shows what appears to be a eucharistic miracle — a consecrated Host exposed for adoration by the faithful seems to “beat” like a heart.

The video was recorded July 23 at Our Lady of the Rosary parish in the town of Zapotlanejo, near Guadalajara, in the Mexican state of Jalisco.

Argentine priest Father Carlos Spahn, founder and superior of the Religious Family of the Immaculate Heart and Divine Mercy, who is currently ministering in Mexico, led the eucharistic adoration service.

In a statement to ACI Prensa, CNA’s Spanish-language sister news agency, Spahn said that the phenomenon occurred after Mass was over: “We exposed the Blessed Sacrament; I said the prayers for the exposition, and when I got up to go to the sacristy, this began to happen.”

“Some people saw it,” he said, and “couldn’t believe what they were seeing, and we have at least two pieces of footage.”

These recordings, he explained, were made by “people who quickly took out their cell phones, filmed it,” and passed it on to him almost immediately, since the priest asked them for that material “so they won’t alter it or anything.”

“So I attest that this is authentic, from the exact moment,” he said.

The priest said that “it’s not that they said aloud ‘look,’” but that the people who were adoring the Blessed Sacrament began to see what was happening, something that lasted “20 seconds, 30 at most.”

The Archdiocese of Guadalajara hasn’t issued a statement on the phenomenon.
