WebApr 14, 2024 · In uncomplicated RBBB, T wave inversion is asymmetrical. Symmetrical inversion (resembling an arrowhead) suggests myocardial damage. 5.4.1 Septal Infarction. Nontransmural septal infarction produces coved ST-segment with symmetrical (arrowhead) T wave inversion in leads V 1 to V 3 (Fig. 28.22). WebMar 29, 2024 · “The resulting ECG may generate erroneous ECG patterns: e.g. in-complete right bundle branch block, anterior T wave inversion, septal Q waves, ST-segment elevation. These features may falsely suggest acute or old cardiac ischemia, pulmonary embolism, or a type-2 Brugada pattern… Precordial lead misplacement can often be identified from the … green economy in south africa pdf
