ABSTRACT
We report the case of a 69 year-old male who developed congestive heart failure functional class IV (NYHA). The admission electrocardiogram (EKG) revealed sinus rhythm, PR interval of 240 ms, QRS interval of 110 ms, the QRS vector of 0 degree, Q waves from V1 to V6, tall R waves from V1 to V4 that decreased to V5 and V6. The vectocardiogram had anteriorization of the electrical forces of QRS, with vector half area in the horizontal plane at +60 degrees. After two years the patient had a myocardial infarction, the EKG at the admission had the same pattern and after two days developed important changes enlargement of QRS interval with length of 160 ms, QRS vector of +100 degrees, R waves at D2, D3 e AVF that increase from D2 to D3, QS at D1, AVL, AVR and V1, rS at V2 and V3, R wave is notched and thickened+ at V5 and V6, that return to the initial pattern after one day. The patient progressed to death in the eighth day after infarction. This case reported a intermitent pattern of EKG that is an uncontestable proof to the existence of the left middle fascicular block.
