Temporary epicardial left ventricular and biventricular pacing improves cardiac output after cardiopulmonary bypass.

Background: To evaluate, with different pacing modes, acute changes in left ventricular systolic function, obtained by continuous cardiac output thermodilution in various subsets of patients undergoing cardiopulmonary bypass surgery. Increments of mean arterial pressure and cardiac output were considered the end point.

Methods: Fifty cases electively submitted to cardiac surgery were analyzed.

Towards symbolization using data-driven extraction of local trends for ICU monitoring.

We propose a methodology for the extraction of local trends from a stream of data. It has been designed to suit the needs of interpretation-oriented visualization and symbolization from ICU monitoring data. After giving implementation details for efficient computation of local trends, we propose the use of a characteristic analysis span for each variable.
