[Dynamic continuous vectorcardiography]

Continuous dynamic vectorcardiography is an ideal method for monitoring patients with myocardial ischemia. The monitoring is a non-invasive and real time registration and simultaneously safe and reproducible. The method has proved valuable for describing the evolution in different ischemic heart diseases. The method measures the electric myocardial activity in three orthogonal leads and a computer calculates the different vectorcardiographic parameters for the ST- and QRS-complexes. Vectorcardiographic registration is feasible for computer analysis, because it can summarize all information in a few parameters. Using continuous registration, the different parameters can show dynamic evolution and, in this way, describe the variability during acute myocardial infarction and unstable angina pectoris. The method also made it possible to evaluate anti-ischemic treatment in patients, as for example thrombolytic therapy.
