Curve Data Problem
Hi,
I have a problem with ECG curve DATA.
I don't know if my understanding or the data is wrong.
Some appilcations show this curve fine so i guess it's me...
I saw few images of different vendors with the same problem
The Curve Data has the following attributes:
5000,0005 Curve Dimensions = 2
5000,0010 Number Of Points = 1360
5000,0020 Type Of Data = ECG
5000,0030 Axis Units = DPPS\NONE
5000,0102 Data Value Representation = 0
The Curve Data size is 2720
To my knowledge the data size should be:
dimensions * number of points * data size
for value representation 0 the data size is 2
so the size should be 2*1360*2 = 5440 but the actual size is
2720  exactly half of the expected....
Any idea ?
Thanks,
Roi

Re: Curve Data Problem
What about the elements (see PS 3.3 C.10.2.1.5):
50xx,0110  Curve Data Descriptor
50xx,0114  Coordinate Step Value
It could mean that you have 2 dimensions but only one
value per point because the other value is determined
by "interval spacing" (as they call it in the standard).
Cheers,
Torsten

Hi Torsten,
Thanks, that was really my problem.
