Characteristics and Mechanisms of Cardiopulmonary Injury Caused by Mine Blasts in Shoals: A Randomized Controlled Study in a Rabbit Model
Figure 3
Electrocardiographic changes following blast injury.
A peaked T-wave (black arrow) was observed at leads I, II and III in this animal from the land group at 9 hours after injury (A). ST-segment reduction (black arrow) was observed after 45 minutes at leads I and II in this animal from the shoal group (B). A pathological Q wave (black arrow) was observed at leads I and II in this animal from the shoal group at 15 minutes after injury (C). Frequent premature ventricular contraction waves (black arrow) were observed at leads I, II and III in this animal from the shoal group at 8 hours after injury, and this abnormality lasted for approximately 1 hour before spontaneously reverting to sinus rhythm (D).
