Ventricular tachycardia and acute heart failure induced by atropine in the treatment of bradycardia: A case report and literature review.

RATIONALE

Despite various advantages of laparoscopic surgical procedures, artificial pneumoperitoneum might lead to hemodynamic fluctuations including severe bradycardia and cardiac arrest. Atropine is usually proposed to treat intraoperative severe bradycardia ( < 40 beats per minute). However, atropine could induce ventricular arrhythmias, which might be life-threatening in severe case.

PATIENT CONCERNS

Here, we reported a 41-year-old female who was diagnosed with gallbladder polyps and was scheduled for laparoscopic cholecystectomy under general anesthesia.

DIAGNOSES

Bradycardia occurred suddenly during the operation and atropine was injected intravenously. Eventually the patient developed ventricular tachycardia and acute heart failure.

INTERVENTIONS

We organized an urgent consultation and the patient was treated immediately.

OUTCOMES

Fortunately, the patient experienced no complications after timely diagnosis and treatment. After 6 months of follow-up, her New York Heart Association classification was I with no complications.

LESSONS

This case highlighted that the administration of atropine to treat bradycardia may lead to ventricular tachycardia and acute heart failure, and anesthesiologists should remain vigilant to avoid potentially life-threatening consequences.
