The aim of the present study was to evaluate the usefulness of the P-wave signal-averaged electrocardiogram (P-SAECG) in predicting the recurrence of AF after initial PVI. The P-SAECG was recorded before and after (within 1 week) the initial PVI session. The filtered P-wave duration (FPD) and root mean square voltage of the last 20ms of the filtered P-wave (LP20) were measured in 87 consecutive idiopathic AF patients (ejection fraction ≥50%, B-type natriuretic peptide ≤200pg/ml). During the follow-up period (12±7 months), 22 of 87 (25%) patients had recurrence of AF (11 with paroxysmal AF and 11 with persistent AF). In the group with recurrence of paroxysmal AF, the post-PVI FPD was significantly shorter and the post-PVI LP20 was significantly larger than in the non-recurrence group. Furthermore, the post-PVI LP20/FPD ratio was significantly higher in the group with paroxysmal AF recurrence than in the non-recurrence group (0.024±0.009 vs 0.015±0.007µV/ms, respectively; P<0.05). Recurrence of paroxysmal AF was more frequently observed in patients with a post-PVI LP20/FPD >0.015µV/ms than in those with a post-PVI LP20/FPD ≤0.015µV/ms. The optimal post-PVI LP20/FPD cut-off value of 0.015µV/ms had a sensitivity of 90% and a specificity of 60%. The data also suggest that the post-PVI LP20/FPD may be a new parameter for predicting successful PVI in patients with idiopathic paroxysmal AF after PVI.","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Showa University Society"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.15369/sujms.29.141"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-6380"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"MUNETSUGU, Yumi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWAMURA, Mitsuharu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TANNO, Kaoru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOBAYASHI, Youichi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-26"}],"displaytype":"detail","filename":"S29_141.pdf","filesize":[{"value":"855.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S29_141.pdf","url":"https://showa.repo.nii.ac.jp/record/515/files/S29_141.pdf"},"version_id":"c00b673e-9ce8-4a25-aae9-52e14e43834e"}]},"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":"departmental bulletin paper"}]},"item_title":"New Parameter to Predict Recurrence of Paroxysmal Atrial Fibrillation after Pulmonary Vein Isolation by the P-Wave Signal-Averaged Electrocardiogram","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"New Parameter to Predict Recurrence of Paroxysmal Atrial Fibrillation after Pulmonary Vein Isolation by the P-Wave Signal-Averaged Electrocardiogram"}]},"item_type_id":"10002","owner":"1","path":["61"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-07"},"publish_date":"2017-12-07","publish_status":"0","recid":"515","relation_version_is_last":true,"title":["New Parameter to Predict Recurrence of Paroxysmal Atrial Fibrillation after Pulmonary Vein Isolation by the P-Wave Signal-Averaged Electrocardiogram"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T12:44:40.329427+00:00"}
