Ventricular ectopy associated with peroral colonic lavage.

W H Marsh, M H Bronner, P L Yantis

    Gastrointestinal Endoscopy
    |August 1, 1986

    Summary

    Peroral colonic lavage solutions, used for colonoscopy preparation, were found to increase ventricular ectopy in patients. This cardiac rhythm change occurred during the lavage preparation phase, highlighting a potential risk during colonoscopy procedures.

    Area of Science:

    • Gastroenterology
    • Cardiology
    • Clinical Medicine

    Background:

    • Peroral colonic lavage solutions are standard for colonoscopy preparation.
    • The impact of these solutions on cardiac rhythm remains unevaluated.
    • Colonoscopy is a common procedure with significant patient preparation requirements.

    Purpose of the Study:

    • To investigate the effects of peroral colonic lavage on cardiac rhythm.
    • To assess changes in ventricular ectopy during colonoscopy preparation.
    • To determine if colonoscopy preparation solutions influence heart rhythm.

    Main Methods:

    • Continuous electrocardiographic (ECG) monitoring was employed.
    • Cardiac rhythm was evaluated in 22 patients undergoing 24 colonoscopies.

  • Monitored periods included baseline, lavage preparation, and colonoscopy phases.

    • Main Results:

    • Increased ventricular ectopy was observed in 12 of 24 evaluations during lavage preparation (p=0.01).
    • Specific findings included ventricular tachycardia (2 patients), complex ventricular ectopy (4 patients), and increased premature ventricular contractions (6 patients).
    • A statistically significant association between colonic lavage and ventricular ectopy was identified.

    Conclusions:

    • Peroral colonic lavage is associated with a significant increase in ventricular ectopy.
    • The findings suggest a potential cardiac risk associated with colonoscopy preparation.
    • Further research may be warranted to explore the mechanisms and clinical significance of these cardiac changes.
