ECG trends from a hunted bear. Sequences automatically recorded from 16:43 - 16:59 on 02-Sep-10 during the time period when bear 6 was legally shot and killed by a hunter. This device was returned to the research team by the hunter. Panels show heart rate trends at the time the bear was shot (upper left) and for the 15 minutes following. The panel at the lower right contains the final heart rate data from this bear. Electromyograms are apparent in the upper left and lower left panels. During the time period shown in the upper right panel (16:49) the heart rate averaged 251 bpm (the numbers at the bottom of the inset ECG trace are the intervals between consecutive heart beats in milliseconds: for example, 230 ms corresponds to a heart rate of 261 bpm).
