The association between coronary artery calcification and vectorcardiography in mechanically ventilated COVID-19 patients: the Maastricht Intensive Care COVID cohort

Intensive Care Medicine Experimental
Background Coronary artery calcification (CAC) is associated with poor outcome in critically ill patients. A deterioration in cardiac conduction and loss of myocardial tissue could be an underlying cause.

Application of vectorcardiography and recurrence-based methods to analysis of ECG signals

MATEC Web of Conferences, 2018
The paper concerns application of vectorcardiography and recurrence-based methods to analyze ECG signals. The first method involves recording the direction and magnitude of electrical forces of the heart by means of a continuous series of vectors that ...

Review of Processing Pathological Vectorcardiographic Records for the Detection of Heart Disease

Frontiers in Physiology, 2022
Vectorcardiography (VCG) is another useful method that provides us with useful spatial information about the electrical activity of the heart. The use of vectorcardiography in clinical practice is not common nowadays, mainly due to the well-established ...
