Ventricular and Atrial Activity Estimation Through Sparse ECG Signal Decompositions

Pierre Vandergheynst, Mathieu Lemay, Lorenzo Granai, Oscar Divorra Escoda

This paper explores a novel approach for ventricular and atrial activities estimation in electrocardiogram (ECG) signals, based on sparse source separation. Sparse decompositions of ECG over signal-adapted multi-component dictionaries can lead to natural s ...

Multiscale Motion Mapping—A Novel Computer Vision Technique for Quantitative, Objective Echocardiographic Motion Measurement Independent of Doppler: First Clinical Description and Validation

Michaël Unser, Michael Sühling, Muthuvel Arigovindan

Background—Objective, quantitative, segmental noninvasive/bedside measurement of cardiac motion is highly desirable in cardiovascular medicine, but current technology suffers from significant drawbacks, such as subjectivity of conventional echocardiographi ...

Relation of effective arterial elastance to arterial system properties

Nikolaos Stergiopoulos, Patrick Segers, Nico Westerhof

Effective arterial elastance (E(a)), defined as the ratio of left ventricular (LV) end-systolic pressure and stroke volume, lumps the steady and pulsatile components of the arterial load in a concise way. Combined with E(max), the slope of the LV end-systo ...

Stimulation by nicotine of enteric inhibitory nerves and release of vasoactive intestinal peptide in the taenia of the guinea-pig caecum

Pierre Magistretti, Jean-Luc Martin

The stimulation by nicotine of intramural nerves and the role of ATP and vasoactive intestinal peptide (VIP) as inhibitory transmitters were studied in the isolated taenia of the guinea-pig caecum. Nicotine (4-32 microM) caused transient, concentration-dep ...
