His ECG showed complete left bundle branch block(LBBB, QRS duration of 146 msec)and echocardiogram showed dyssynchrony. The patient was diagnosed with heart failure due to significant pulmonary congestion, but his subsequent treatment was poor. We report here a case of shortened QRS width, improved dyssynchrony, and recovery of cardiac function after left branch bundle pacing. In this case, we report the use of TomTec-Arena, a new evaluation method for dyssynchrony.","PeriodicalId":14543,"journal":{"name":"Japanese Journal of Electrocardiology","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76002643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, qunidine sometimes has been used as an antiepileptic drug. To date, However, there are few reports of its use in children or reports of side effects. The case is a 2-year-old boy with epilepsy with migrating focal seizures. Various antiepileptic drugs and corpus callostomy were ineffective, and quinidine was introduced. The dose was increased while frequently confirming blood concentration. Seizures decreased as the dose increased. One year after introducing quinidine, he was hospitalized for gastrostomy, bradycardia and hypotension and required rapid administration of saline and catecholamine temporarily. Blood concentration during hypotension was within the therapeutic range, but the electrocardiogram showed marked QT prolongation and bradycardia. It is necessary to manage quinidine as an antiepileptic drug by paying attention not only to blood concentration but also to changes in electrocardiogram and hemodynamics.","PeriodicalId":14543,"journal":{"name":"Japanese Journal of Electrocardiology","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79214053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the ventricular captured beats showed right bundle branch block(RBBB)axis +30°(A), 2 patterns of escape beats, i.e. RBBB axis +60°(B)and left bundle branch block(LBBB)(C), were observed with cycle lengths 1.65 and 1.68 sec, respectively. Fusion beats of various degrees between B and C were also observed. When RP interval was> 0.89 sec, the P wave depolarized the escape focus antegradely. When RP interval was ≤ 0.88 sec, the P wave did not antegradely depolarize the escape focus but retrogradely depolarized it with some delay, conducting via the lower portion of His bundle transversely. QRS axis of B showed mild rightward shift compared with that of A. With the aforementioned electrocardiographic findings, we concluded that His bundle was functionally dissociated into triple pathway. In addition, the P wave conducting through the bundle connecting to the left posterior bundle branch caused A, and two escape focuses localized in the bundles connecting to the left anterior bundle branch and right bundle branch caused B and C, respectively.","PeriodicalId":14543,"journal":{"name":"Japanese Journal of Electrocardiology","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76405044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
