    Area of Science:

    • Cardiology
    • Electrophysiology
    • Medical Technology

    Background:

    • Elderly patients often present with complex cardiovascular and respiratory conditions.
    • Atrial arrhythmias pose significant challenges in managing patients with coronary heart disease and chronic pulmonary disease.
    • Accurate analysis of atrial arrhythmias is crucial for effective treatment strategies.

    Purpose of the Study:

    • To present a case series of two elderly patients with complex comorbidities and atrial arrhythmias.
    • To evaluate the utility of the suction electrode technique for right atrium monophasic action potential recording.
    • To demonstrate the technique's ability to improve the analysis of atrial arrhythmias and focal activity stability.

    Main Methods:

    • Utilized the suction electrode technique for right atrium monophasic action potential recording.
    • Applied the technique to two elderly patients with coronary heart disease, chronic pulmonary disease, and complex atrial arrhythmias.
    • Analyzed the recorded monophasic action potentials to assess arrhythmia characteristics.

    Main Results:

    • The suction electrode technique provided detailed monophasic action potential recordings from the right atrium.
    • The recordings facilitated a more precise analysis of the complex atrial arrhythmias in the presented cases.
    • The technique allowed for an estimation of the stability of focal atrial activity.

    Conclusions:

    • The suction electrode technique is a valuable tool for analyzing atrial arrhythmias in complex patient populations.
    • This method offers improved insights into arrhythmia mechanisms and stability compared to conventional techniques.
    • Further research may explore the broader application of this technique in clinical electrophysiology.
