Abstract: An assembled furniture comprising a plurality of plates, wherein two adjacent plates are provided respectively with a through hole and a bump that are mutually matched, a second through hole is arranged on the bump, the bump is penetrated into the through hole, and a locking block is plugged in the second through hole of the bump. The bump of a plate is penetrated into the through hole of an adjacent plate, and then the locking block is plugged into the second through hole of the bump, to form various furniture. During disassembly, the locking block is pulled out from the second through hole of the bump first, and then the bump is pulled out from the through hole, to disassemble the furniture. The assembly and disassembly are convenient and quick.

Abstract: A device and method for displaying medical data for a stress test monitoring system. A computer-implemented method and apparatus for displaying electrical impulse data of a human heart for analysis includes receiving cardiac electrical impulse data produced during a cardiac stress test by a plurality of electrode leads adapted for placement on a patient and calculating parameters for a plurality of display windows based on the data and providing a main display in which the plurality of display windows are positioned. A three dimensional color mapping plot is displayed in one of the plurality of display windows and a two dimensional color mapping plot is displayed in another of the plurality of display windows. Additionally, a plot of raw lead data from at least one lead is displayed in one of the plurality of display windows.
