Alligator hearts keep beating no matter what

A new study finds that an alligator heart will not fibrillate when exposed to drastic temperature changes, unlike a rabbit (mammal) heart, which is critically vulnerable to heart trauma under those conditions. The research could help better understand how the heart works and what can cause a deadly arrhythmia - which fundamentally happens when the heart doesn't pump blood correctly any longer.
