Vectorelectrocardiography in coronary artery disease.

Continuous ST-segment monitoring by either continuous 12-lead ECG or continuous vectorcardiography provides reliable information regarding ST changes in patients with ongoing myocardial ischemia with or without concurrent chest pain. ST-segment monitoring enables the clinician to continuously follow the dynamic changes that characterize unstable angina and acute myocardial infarction syndromes. It provides important information for risk stratification in unstable coronary syndromes and helps in differentiating between extra-cardiac chest pain and acute coronary disease. The use of VECG for detection of perioperative myocardial damage is promising but much work still needs to be done to clarify the prognostic and clinical value of VECG in this setting.
