    Fiberoptic bronchoscopy monitoring revealed significant sinus tachycardia in patients, though overall ectopy did not increase. This procedure is generally safe for cardiac patients, but caution is advised for those with coronary heart disease.

    Area of Science:

    • Cardiology
    • Pulmonology
    • Medical Procedures

    Background:

    • Electrocardiogram (ECG) monitoring is crucial during invasive procedures.
    • Fiberoptic bronchoscopy is a common diagnostic and therapeutic tool.
    • Cardiac implications of fiberoptic bronchoscopy require thorough investigation.

    Purpose of the Study:

    • To assess ECG changes during fiberoptic bronchoscopy.
    • To evaluate the impact of the procedure on heart rate and ectopic beats.
    • To identify potential risks in patients with pre-existing heart disease.

    Main Methods:

    • ECG monitoring of 51 patients undergoing fiberoptic bronchoscopy.
    • Comparison of ECG recordings before and during the procedure.
    • Analysis of heart rate, atrial, and ventricular ectopic beats.

  • Stratification of patients with and without heart disease.

    • Main Results:

    • A significant increase in heart rate (sinus tachycardia) was observed during the procedure.
    • No significant increase in atrial or ventricular ectopic beats was noted.
    • Ventricular ectopy did not worsen, even in patients with coronary heart disease.
    • No instances of ventricular tachycardia occurred.

    Conclusions:

    • Fiberoptic bronchoscopy primarily induces sinus tachycardia, which is generally well-tolerated.
    • The procedure does not appear to exacerbate pre-existing ectopy.
    • Coronary heart disease patients may be at increased risk for ischemia due to tachycardia, warranting careful monitoring.
