PURPOSE: To effectively detect an artifact, to reduce a pseudo positive ratio in VPC detection and to improve global analysis accuracy in the VPC detecting processing of electrocardiogram analysis. CONSTITUTION: This system is provided with a first calculation part 1 which calculates a morphological parameter for each heartbeat, a ring buffer manager 2 which registers past ten heartbeats on a ring buffer 8, a second calculation part 3 which calculates the mean value of the heartbeats in the ring buffer 8, a first decision part 4 which decides the possibility of the artifact from a change rate with the mean value, a third calculation part 5 which calculates the morphological parameter of a T wave, a second decision part 6 which decides he existence of the T wave from a calculated numeric value, and an analysis part 7 which analyzes an electrocardiogram from which the artifact is removed. |
