Panic Beats (Spanish: Latidos de Pánico) is a 1983 film starring Paul Naschy and Julia Saly.

Paul Naschy plays the monstrous Alaric de Marnac and Julia Saly, Lola Gaos, and Silvia Miro co-star.

He brings her to stay for a few months at his parents' old mansion in the country, telling her the peace and serenity will improve her heart condition.

Meanwhile he is scaring her with legends of his 15th century ancestor, an evil murderous knight named Alaric de Marnac, making her think the monster still inhabits the house.

Paul even goes so far as to disguise himself as Alaric, wearing a 15th century suit of armor, and succeeds in scaring the poor woman to death.
