METHODS AND MATERIALS: After a phantom study confirmed the safety of PBT in patients with cardiac pacemakers, we treated 8 patients with implanted pacemakers using PBT to a total tumor dose of 33-77 gray equivalents (GyE) in dose fractions of 2.2-6.6 GyE. The combined total number of PBT sessions was 127. Although all pulse generators remained outside the treatment field, 4 patients had pacing leads in the radiation field. All patients were monitored by means of electrocardiogram during treatment, and pacemakers were routinely examined before and after PBT. RESULTS: The phantom study showed no effect of neutron scatter on pacemaker generators. In the study, changes in heart rate occurred three times (2.4%) in 2 patients. However, these patients remained completely asymptomatic throughout the PBT course. CONCLUSIONS: PBT can result in pacemaker malfunctions that manifest as changes in pulse rate and pulse patterns. Therefore, patients with cardiac pacemakers should be monitored by means of electrocardiogram during PBT.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0360-3016","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Oshiro, Yoshiko"}],"nameIdentifiers":[{"nameIdentifier":"453132","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugahara, Shinji"}],"nameIdentifiers":[{"nameIdentifier":"453133","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"453134","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菅原 信二","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"453135","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Proton Beam Therapy Interference with Implanted Cardiac Pacemakers","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Proton Beam Therapy Interference with Implanted Cardiac Pacemakers"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-08-06"},"publish_date":"2009-08-06","publish_status":"0","recid":"45601","relation_version_is_last":true,"title":["Proton Beam Therapy Interference with Implanted Cardiac Pacemakers"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:01:48.291482+00:00"}
