However, in a study of dogs envenomated by V. berus; differences in cTnI concentrations in dogs, with and without arrhythmias, at admission and 12–24 h after admission could not be detected, and 30% of included dogs had increased cTnI concentrations 5–10 days post admission [10]. The gene discussed is TNNI3; the disease is cardiac arrhythmia.
