EKG diagnosis: On the EKG if the qrs (electrical wave cause by the heart muscle depolarizing) is 0.12 seconds or greater, it is by definition complete. Less that that would be incomplete. Complete implies that there is no conduction at all and incomplete that it is just delayed. However, that number is somewhat arbitrary.
