    This study presents two cases of bidirectional tachycardia, confirming it describes an electrocardiographic pattern with diverse underlying electrophysiological mechanisms. These findings highlight the importance of understanding varied causes for this specific arrhythmia presentation.

    Area of Science:

    • Cardiology
    • Electrophysiology
    • Cardiac Arrhythmias

    Background:

    • Bidirectional tachycardia is a rare ventricular arrhythmia.
    • Its precise electrophysiological mechanisms can be complex and varied.
    • Accurate diagnosis is crucial for effective management.

    Observation:

    • Two distinct cases of bidirectional tachycardia were analyzed.
    • His bundle recordings were utilized to confirm ventricular origin.
    • Atypical features, including specific V1 morphology and unknown etiology, were noted in the cases.

    Findings:

    • The ventricular origin of the arrhythmias was confirmed.
    • The cases presented atypical electrocardiographic patterns.
    • The study discusses various mechanisms and inducing factors for these tachycardias.

    Implications:

    • The findings support using 'bidirectional tachycardia' as an electrocardiographic pattern descriptor.
    • Different electrophysiological mechanisms can manifest as this pattern.
    • Further research into the specific causes and management of atypical bidirectional tachycardia is warranted.
