Plain-English summary

A 9.5-year-old dog was brought in for slow heart rate (bradycardia) after being hit by a car. Tests showed that the dog had a serious heart condition called third-degree AV block, which means the heart was not beating properly. Unfortunately, the dog passed away during a fainting episode. A post-mortem exam revealed severe heart damage, including a tear in the heart's wall and bleeding.
