Many of use have watched medical drama (the Great White Tower, House, Gray's Anatomy [bad bad bad medicine] etc). Obviously here are patients who go into asystole, then people perform CPR. (ignoring the fact that most in most TV movies or series, people can regain consciousness ALL the time) When performing CPR on a patient in asystole, will it show on the Pulse Monitor (or whatever is it, that shows your heart pumping (ECG??)? Like when you compress, will the ECG show a spike, or will it still keep a flatline? My first thought is that it won't show any 'spikes' because the ECG measures electronic signals?
