[Right bundle-branch block configuration in the pacemaker ECG--3 different observations].

G Richter, A Kehl, L Eckel

    Zeitschrift Fur Kardiologie
    |April 1, 1986
    PubMed
    Summary

    Pacemaker implantation can lead to right bundle branch block due to unusual catheter placement. Imaging and ECG help detect these critical misplacements.

    Area of Science:

    • Cardiology
    • Medical Devices
    • Electrophysiology

    Background:

    • Pacemaker implantation is a common procedure for managing bradyarrhythmias.
    • Right bundle branch block (RBBB) can be an unexpected finding post-pacemaker insertion.
    • Understanding potential causes of RBBB is crucial for patient safety.

    Observation:

    • Three cases are presented where RBBB occurred after pacemaker implantation due to malpositioned leads.
    • Case 1: Lead traversed a sinus venosus defect into the left atrium and ventricle.
    • Case 2: Lead perforated the atrial septum, entering the left ventricle.
    • Case 3: Lead tip penetrated the ventricular septum from the right ventricle.

    Findings:

    • Unusual pacemaker lead placement, including atrial and ventricular septal defects or perforation, can mimic or cause RBBB.
    • Misplacement into the left-sided circulation or through the septum requires prompt identification.
    • Specific malpositions, such as in the coronary sinus or pericardial space, are also discussed.

    Implications:

    • Accurate interpretation of electrocardiograms (ECGs) and imaging is vital for detecting lead misplacement.
    • Diagnostic tools like lateral radiography, 12-lead ECG, and echocardiography are essential.
    • Preventing lead placement in arterial areas, pericardial space, and coronary sinus is critical for optimal pacemaker function and patient outcomes.
