Has anyone lived without the heart?

A person with a non-functioning SA node may live out their life normally, since there are other cells in the heart that possess pacemaker capabilities. The heart would continue to beat in this situation, although at a slower pace.

Excerise would be dangerous because the heart would NOT be able to speed up properly. In this case if the SA node - fails a pacemaker can be fitted. Other heart cells can take over as the hearts pacemaker. Junctional escape will occur for more information visit my pageHow_heart_works
