Resumen:
This work evaluates the vectorcardiographic dynamic
changes in ischemic patients before and during Percutaneous Transluminal
Coronary Angioplasty (PTCA). Four vectorcardiographic parameters were
computed in 51 ischemic and 52 healthy subjects with the objective of assessing
the differences between both groups: ST Vector Magnitude Area (STVMa), T Vector Magnitude Area (TVMa), ST Vector Difference (STVD), and T Vector Difference (TVD). The conventional ST-Change Vector Magnitude (STCVM) and Spatial Ventricular Gradient (SVG) were
also calculated. Results indicate that the most of them show significant
differences between healthy and ischemic subjects. Since, the statistical
minute-by minute PTCA comparison against a healthy population shows that
ischemic patientsmonitoring reached values of Sensitivity = 99.5% and Specificity = 99.4%,
when STVD, TVD and SVG were used in the classification. In conclusion the sensitivity and specificity for
acute ischemia
monitoring could be increase with the used of only three vectorcardiographic parameters.
