Quantitative Assessment of Vectorcardiographic Loop Morphology

Quantitative comparison of eight vectorcardiographic lead systems.

Vectorcardiographic T loop analysis in ischaemic heart disease.

Vectorcardiographic T loops were studied in 1O0 patients undergoing selective coronary angiography for the evaluation of chest pain. The T loops were recorded simultaneously with an electrocardiogram before and after the completion of a standard Master's two-step exercise test. A positive ischaemic change in the electrocardiogram was greater than or equal to I mm offlat ST segment depression, w...

Using Intracardiac Vectorcardiographic Loop for Surface ECG Synthesis

Current cardiac implantable devices offer improved processing power and recording capabilities. Some of these devices already provide basic telemonitoring features that may help to reduce health care expenditure. A challenge is posed in particular for the telemonitoring of the patient’s cardiac electrical activity. Indeed, only intracardiac electrograms (EGMs) are acquired by the implanted devi...

Quantitative assessment of corpus callosum morphology in periventricular nodular heterotopia.

We investigated systematic differences in corpus callosum morphology in periventricular nodular heterotopia (PVNH). Differences in corpus callosum mid-sagittal area and subregional area changes were measured using an automated software-based method. Heterotopic gray matter deposits were automatically labeled and compared with corpus callosum changes. The spatial pattern of corpus callosum chang...

Computer-Based Quantitative Assessment of Skull Morphology for Craniosynostosis

In this paper we present a processing pipeline for the computational analysis of the craniosynostotic skull. Our fully automatic methodology uses a statistical shape model in order to produce diagnostic features tailored to the anatomy of the subject. We obtained an index of cranial suture closure and deformation and curvature averages across five bone segments and six suture regions automatica...
