    Summary
    This summary is machine-generated.

    Sinus node dysfunction can cause life-threatening emergencies. Eight patients required interventions like pacing or pacemaker implantation to manage these critical situations.

    Area of Science:

    • Cardiology
    • Electrophysiology

    Background:

    • Sinus node dysfunction (SND) is a condition affecting heart rhythm.
    • It can manifest with bradycardia (slow heart rate) or pauses.

    Observation:

    • This study reviewed 138 patients with SND.
    • Eight patients experienced medical emergencies requiring immediate intervention.
    • Emergencies arose spontaneously, during investigations, or post-atrial fibrillation conversion.

    Findings:

    • Interventions included precordial thump, temporary pacing (atrial/ventricular), and permanent pacemaker implantation.
    • Atrial fibrillation conversion sometimes unmasked underlying SND.
    • Tachy-brady-arrhythmia associated with SND was effectively managed only by permanent pacemaker implantation.

    Implications:

    • Prompt recognition and management of SND emergencies are crucial.
    • Permanent pacemaker implantation is a definitive treatment for refractory SND with tachy-brady-arrhythmia.
    • Understanding SND's presentation post-atrial fibrillation conversion is important for patient care.
