The continuous change of the ST and QRS vectorcardiograms reflect the underlying ischemic event, and can be used as a tool in the management of the acute event. It also reflects reperfusion, and can guide the clinician on when and how to intervene. Continuous vectorcardiography has proven to add prognostic information, both in the acute phase (can be used already in the ambulance during transportation to CCU) and after discharge from hospital. This paper reviews the origin of continous vectorcardiography as a monitoring device in AMI, including the follow-up research until today.
