Abstract: A method for analysing an intracardiac electrogram (1) for detecting a pulmonary vein (2) isolation status via a control system (3), wherein the intracardiac electrogram has been recorded at a target region (4) via a catheter (5) inserted into a human, wherein the catheter includes multiple electrodes (7), wherein multiple channels (10) of the intracardiac electrogram have been recorded by the electrodes, wherein the electrodes have a fixed order of placement, wherein in an analysis routine (11), the control system determines an electrical status of the target region by analysing at least three of the channels. The order of the electrodes on the catheter is provided to the control system or saved in a memory (13) of the control system. In the analysis routine the control system determines the electrical status of the target region based on spatial information including the order of placement of the electrodes on the catheter.

Abstract: The invention relates to methods for analysis of particles in a liquid sample, the sample being retained in a sample retaining device, the method comprising: acquiring, by means of an image acquiring device, a plurality of images of said sample at different focus planes within the sample retaining device; analysing said images, by means of an image analyser, for identifying which, if any, of the particles of the sample are imaged in focus in each of the images, and analysing those particles which have been identified as being imaged in focus; wherein said plurality of images are acquired at different, essentially parallel, focus planes, which planes are separated from each other by a distance, said distance being less than 10 micrometers. The invention also relates to apparatuses adapted to be used for the inventive methods.
