A closer look
Despite what television doctors passionately scream, you cannot electrically jumpstart a heart that has flatlined. Defibrillators are completely useless on a perfectly still chest. They are exclusively used for dangerous arrhythmias, where the muscle is fluttering wildly out of sync. The massive jolt of electricity aggressively stuns the entire organ, briefly stopping everything entirely in hopes that the body's natural pacemaker will politely reboot with a normal rhythm.
