The numbness probably is not due to your heart, more likely some nerve is getting impridged
because of the stimulating properties of cocaine
Im assuming that some muscle spasmed (because cocaine is a stimulant it makes skeletal muscles fill with blood etc, getting them ready to act, fight or flight etc) compressing some nerve, when that spasm subsides the nerve sould be freed and the numbness releaved but then again it might not be that, it might be something completely different, doing a diagnosis from the web is just not possible... If it persists more than 3-4 days go to a doctor beacause it might be something serious or it could get permenant...
