However, about 30% of patients who undergo CRT do not receive any benefit. Therefore, we investigated the usefulness of the QRS-left ventricle (LV) interval for predicting responders during CRT implantation. This study included 66 patients who underwent CRT implantation. The definition of responder was a ≥15% reduction in LV end-systolic volume or ≥20% increase in LV ejection fraction. The QRS-LV interval was measured from the beginning of the body surface electrocardiogram QRS complex to the LV potential recorded by LV leads. We analyzed the correlations between the QRS-LV intervals and CRT responders, admission for HF and mortality. The patients were 67±12 years old, and their mean LV ejection fraction was 26.3%±8.3%. During follow-up (27.2±19.9 months), 27 patients were admitted for HF (40.1%), and 17 died (25.7%); the median QRS-LV interval was 103±33 msec. Patients were divided into 2 groups: wide QRS-LV (>103 msec), and narrow QRS-LV (<103 msec). The wide QRS-LV group had a lower mortality rate than the narrow QRS-LV group (77% vs. 53%, P<0.05). In patients with dilated cardiomyopathy, the QRS-LV interval was significantly wider in responders, compared to non-responders (112±9.2 vs. 80.0±10 msec, P<0.05). The QRS-LV interval did not correlate with CRT responders or admission for HF. The mortality rate was lower in patients with wide QRS-LV intervals, compared to narrow QRS-LV intervals. Furthermore, a wide QRS-LV interval might be a predictor for CRT responders in patients with dilated cardiomyopathy.","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.29.131"}}]},"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":"ONUMA, Yoshimasa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWAMURA, Mitsuharu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YOSHIKAWA, Kosuke"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"GOKAN, Toshihiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OGAWA, Ko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKAMURA, Yuya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OCHI, Akinori"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"INOKUCHI, Koichiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUNETSUGU, Yumi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ONUKI, Tatsuya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITO, Hiroyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WATANABE, Norikazu"}],"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_131.pdf","filesize":[{"value":"218.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S29_131.pdf","url":"https://showa.repo.nii.ac.jp/record/514/files/S29_131.pdf"},"version_id":"289f0c0a-f1a0-4cf1-94c8-2dfefa84f794"}]},"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":"Usefulness of Intracardiac Local Ventricular Electrogram to Predict Responders in Patients Undergoing Cardiac Resynchronization Therapy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Usefulness of Intracardiac Local Ventricular Electrogram to Predict Responders in Patients Undergoing Cardiac Resynchronization Therapy"}]},"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":"514","relation_version_is_last":true,"title":["Usefulness of Intracardiac Local Ventricular Electrogram to Predict Responders in Patients Undergoing Cardiac Resynchronization Therapy"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T12:44:42.407302+00:00"}
