Bradycardia, sinus arrest, and second-degree atrioventricular block developed in 2 dogs with tetanus. Clinical signs attributable to bradycardia were not apparent. Administration of atropine resulted in resolution of the arrhythmias. Both dogs responded well to supportive treatment; the bradycardia resolved within 4 days of onset without specific treatment. Tetanus should be included in the differential diagnosis when increased neuromuscular excitability and bradycardia are evident, as is found in toxicity with acetylcholinesterase inhibitors, increased intracranial pressure, and other neurologic disorders.
2只患破伤风的犬出现了心动过缓、窦性停搏和二度房室传导阻滞。由心动过缓引起的临床症状并不明显。给予阿托品后心律失常得到缓解。两只犬对支持治疗反应良好；心动过缓在发病后4天内自行缓解，未进行特殊治疗。当出现神经肌肉兴奋性增加和心动过缓时，如在乙酰胆碱酯酶抑制剂中毒、颅内压升高及其他神经系统疾病中所见，破伤风应列入鉴别诊断。
