Key result
Vectorcardiographic parameters may predict CRT response better than conventional QRS duration and morphology.
Why the study?
Do advanced ECG-based biomarkers like the vectorcardiogram improve patient selection for cardiac resynchronization therapy compared to standard QRS duration and morphology?
Do advanced ECG-based biomarkers like the vectorcardiogram improve patient selection for cardiac resynchronization therapy compared to standard QRS duration and morphology?
Replacing standard QRS duration with more advanced measures of electrical activation, such as the vectorcardiogram, may improve patient selection and reduce non-response rates in cardiac resynchronization therapy.

Hypothesis-generating for vectorcardiography in CRT selection; prospective validation needed before clinical adoption.
Engels et al. (2016) conducted a review in Heart failure. Vectorcardiogram (VCG) parameters (QRS AREA, T-wave area) vs. QRS duration and morphology was evaluated. Vectorcardiographic parameters such as QRS area and T-wave area may provide better prediction of response to cardiac resynchronization therapy compared to conventional QRS duration and morphology.
