PERIANESTHETIC ARRHYTHMIAS—WHAT IS IT AND WHAT DO I DO NOW?

摘要

Cardiac arrhythmia may be defined as an irregularity in the cardiac rhythm. They are typically classified according to origin, rate, or regularity. Arrhythmias may occur from cardiac and/or extra cardiac reasons.Bradycardia is commonly seen with the anesthetized patient. Commonly the cause is dose related to the anesthetic and/or analgesic agents used. If the heart rate is low with a normal sinus rhythm and supporting blood pressure, be aware, be prepared to treat but be tolerant of a slow rate. If hypotension is noted in addition to a slow rate, an anticholinergic may be indicated to increase output by raising rat; this is particularly true with pediatric and juvenile patients.
