Summary

Upper gastrointestinal endoscopy is generally safe for cardiac patients. Avoiding anticholinergic agents reduces heart rate increases during the procedure, though careful monitoring is still advised.

Area of Science:

  • Cardiology
  • Gastroenterology

Background:

  • Upper gastrointestinal endoscopy is a common procedure.
  • Cardiac function monitoring during endoscopy is crucial for patient safety.

Purpose of the Study:

  • To investigate the cardiac effects of upper gastrointestinal endoscopy.
  • To evaluate the impact of anticholinergic premedication on cardiac function during endoscopy.

Main Methods:

  • Cardiac function was monitored using a Holter electrocardiorecorder in 54 subjects undergoing upper gastrointestinal endoscopy.
  • Patients were divided into groups with and without anticholinergic premedication.
  • Heart rate changes were analyzed in relation to endoscopy experience and premedication status.

Main Results:

Related Experiment Videos

  • Patients receiving anticholinergic agents showed a greater heart rate increase compared to those without.
  • Sinus tachycardia was observed in the no-premedication group; one patient experienced atrial flutter from atrial fibrillation.
  • Heart rate increased in first-time endoscopy patients but not in those with prior experience.

Conclusions:

  • Upper gastrointestinal endoscopy is relatively safe concerning cardiac risk when anticholinergic agents are avoided.
  • Cardiac patients require careful monitoring during endoscopy.
  • Endoscopists should consider patient anxiety and psychological state.
