Detailed description of the invention
The embodiment of the invention discloses a kind of wave label method, its central inventive point is, mark position user inputted on waveform corresponds to labelling time value, labelling time value is stored, on the basis of described wave label method, when display waveform, obtain labelling time value, corresponded to location of pixels, in the label symbol that the display of described location of pixels is preset so that on waveform show tags point.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of wave label method disclosed in the embodiment of the present invention, is applied to the waveform that variable is the time, and as shown in Figure 1, described method comprises:
S101: receive the mark position that user inputs on waveform;
Usually, user can use the input equipment such as mouse or keyboard input marking position on waveform.
S102: time value corresponding for the mark position of acquisition is defined as labelling time value;

Particularly, the acquisition that can be inputted by user, namely user inputs title of leading, and also can identify and lead, concrete recognition methods can be:
By inquiring about the region at described mark position place, determine leading of described mark position place.
Because during waveform display each leading have respective viewing area, describedly can determine leading of labelling place according to mark position region.
Property parameters can intactly and uniquely describe an electrocardio gauge point, is convenient to for doctor provides reference.
S404: store described labelling time value, and with the property parameters of mark position described in described labelling time value corresponding stored, to complete the labelling to described mark position.
