Diagnosis of myocardial infarction complicated by complete block of the left branch of His bundle as shown by computed electrocardiotopography

摘要

AIM: To assess efficacy of computed electrocardiotopography (CECT) in diagnosis of myocardial infarction (MI) complicated by a complete block of His' bundle left branch (HBLB). MATERIAL AND METHODS: Twenty two patients with a complete block of HBLB have undergone CECT (hardware Rhythm-M, software "Rhythm" and "Heart"). RESULTS: Five patients had no scars. The rest 17 patients had MI. The diagnosis of MI was definite by ECG in 6 (35%) patients. In 11 (65%) patients MI diagnosis by ECG was doubtful. Only CECT detected typical for MI changes in the QRS changes. CONCLUSION: CECT can significantly detect scars in the myocardium in a complete block of HBLB and improves diagnostic potential of ECG.
