Diagnosis of myocardialinfarction complicated by a complete block of His' bundleleft branch as shown by computed electrocardiotopography

Abstract

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.
