Abstract:
Norepinephrine (NE) can raise blood pressure and speed up heart rate. However, because its effect of raising heart rate is less than that of reflex reduction of heart rate caused by the increase of blood pressure, NE causes more heart rate decrease in patients. A case of tachyarrhythmia caused by low dose NE was admitted to department of intensive care unit (ICU) of Shijiazhuang Third Hospital. The heart rate of the patient increased with the elevation of NE application dose. A variety of antiarrhythmic drugs was invalid. The related examination was prescribed to eliminate the cause of arrhythmia caused by the disorder of electrolysis and thyroid function, and found that heart rate decreased as the dose of NE tapered. After NE was stopped, the patient recovered sinus rhythm. During one month of follow-up, the patient's heart rhythm was normal. Therefore, the occurrence of tachyarrhythmia is related to NE.
