Cardiac rhythm in men during cystoscopy.

H M Kimbrough, R S Crampton, J Y Gillenwater

    The Journal of Urology
    |June 11, 1975
    PubMed
    Summary

    Men with heart disease experienced more cardiac arrhythmias during cystoscopy. Local lidocaine anesthesia increased ventricular ectopic beats compared to general or epidural anesthesia, though no permanent complications occurred.

    Area of Science:

    • Urology
    • Cardiology
    • Anesthesiology

    Background:

    • Cardiac rhythm disturbances can occur during cystoscopy.
    • Patients with pre-existing heart disease may be at higher risk.
    • The type of anesthesia used might influence the incidence of arrhythmias.

    Purpose of the Study:

    • To prospectively monitor cardiac rhythm in men undergoing cystoscopy.
    • To investigate the association between heart disease and arrhythmias during the procedure.
    • To compare the incidence of arrhythmias based on the type of anesthesia administered.

    Main Methods:

    • Prospective cardiac rhythm monitoring in 69 men during 191 cystoscopies.
    • Assessment of arrhythmias in patients with and without heart disease.
    • Analysis of arrhythmias in relation to local lidocaine, general, and epidural anesthesia.

    Main Results:

    • Men with heart disease had a significantly higher proportion of procedures with ectopic beats (76%) compared to those without (16%).
    • Local lidocaine anesthesia was associated with a significantly higher rate of ventricular ectopic beats (48.7%) than general (8%) or epidural (13.8%) anesthesia.
    • Plasma lidocaine was detected following intraurethral injection; no significant difference in supraventricular ectopic beats was observed across anesthetic groups.

    Conclusions:

    • Cystoscopy is associated with an increased risk of arrhythmias, particularly in men with heart disease.
    • Local lidocaine anesthesia increases the risk of ventricular ectopic beats during cystoscopy.
    • While potentially serious dysrhythmias were observed, no permanent cardiovascular complications occurred.
