There is provided piezoelectric devices for restoring normal contraction rhythms of a heart, or for pacing a heart, comprising a housing having an electrically conducting portion, a piezoelectric generator within the housing and electrically insulated from the housing, th e piezoelectric generator having first and second electrical conductors, the first conductor being electrically connected to the electrically conducting portion of the housing, an electrically conductive skin contact electrode having a skin contact portion, the electrode being electrically insulated from the conducting portion of the housing, and being in electrical connection with t he second conductor, and an actuator for actuating the piezoelectric generator to generate an electrical current in response to stimuli from a user. There is further provided methods for restoring normal contraction rhythms of a heart in cardiac arrest, or for pacing a heart, comprising the administering an electric shock from a piezoelectric device to the chest are a of a mammal proximal the heart. The use of a piezoelectric device for such functions is also provided.
