We have optically mapped electrical activity of the left ventricular subepicardial layer of Langendorff-perfused rabbit hearts endocardialy frozen. Monophasic anodal and cathodal shocks were applied during the plateau or repolarization phase of the action potential. Electric shocks (20V, 10 ms) resulted in a “dog-bone”pattern  of polarization around the stimulation electrode and withdrawl of the shocks were followed by \"break excitations\". Spread of the break excitations were partially blocked by refractory of the preceding excitation, and slow cunduction around the functional line of block initiated reentrant excitations. These results suggest that break excitations arising from the virtual electrode polarization combined with spatial heterogeneity in repolarization of the preceding excitation play important roles in the genesis of post-shock reentrant activities.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"国立情報学研究所で電子化したコンテンツを使用している。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/7595"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/envm.47.62","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Research
