Fragmented QRS complexes (fQRS) in the right precordial leads are associated with occurrence of ventricular fibrillation (VF) Brugada syndrome. Recently, epicardial mapping has revealed abnormal electrograms at (RV) outflow tract and inferior region ventricle. fQRS may reflect extent area potentials, but whether distribution prognostic value is not known.We evaluated existence 456 patients syndrome, including 117 syncope 23 VF. The was defined as (II, III, aVF), lateral (I, aVL, V5 V6),...
Introduction Optimization of cardiac resynchronization therapy (CRT) using a 12-lead electrocardiogram (ECG) alone may not sufficiently improve left ventricular (LV) function in all cases. Therefore, we aimed to investigate whether additional optimization transthoracic echocardiography (TTE) could further enhance CRT efficacy. Methods Sixty-five patients who underwent implantation between March 2018 and July 2022 at Sakakibara Heart Institute, Japan, were included this study. Data collected...
The eligibility of patients with Brugada syndrome (BrS) for implantation a subcutaneous implantable cardioverter defibrillator (S-ICD) is not well known. This study aimed to clarify the BrS S-ICD using electrocardiography (ECG) at rest and during exercise testing. We also analyzed factors associated ineligibility from standard 12-lead ECG rest.We enrolled 110 consecutive who visited Okayama university hospital December 2015 2016. All were assessed eligibility, which required one lead satisfy...
Abstract Background The safety and efficacy of the leadless pacemaker (LP) have been confirmed in previous reports, yet studies on LPs superelderly patients are limited. Methods Results A total 62 aged over 85 years old were implanted with single‐chamber pacemakers due to symptomatic bradyarrhythmia at Sakakibara Heart Institute from May 2014 through July 2019. We divided them into two groups, a transvenous (TV) group (35 patients) an LP (27 patients), compared groups. Mean participant age...
Abstract Background Compared to screening ECG before implantation of a subcutaneous implantable cardioverter‐defibrillator (S‐ ICD ), selectable vectors without T‐wave oversensing increase after S‐ implantation. Newer algorithms have recently become available reduce oversensing, such as SMART pass ( SP ). With this function, more are identified However, improvement in eligibility utilizing has not yet been well validated. We aimed clarify and with . Methods Participants comprised 34 patients...
Background A drug provocation test using a sodium channel blocker ( SCB ) can unmask type 1 ECG pattern in patients with Brugada syndrome. However, the prognostic value of results an challenge is limited non–type . We investigated associations future risk for ventricular fibrillation ‐induced changes and tachyarrhythmias VTA s). Methods Results administered intravenous pilsicainide to 245 consecutive syndrome (181 spontaneous , 64 ). parameters before after occurrence drug‐induced s were...
Fast junctional rhythm (JR) during slow pathway modification for atrioventricular nodal reentrant tachycardia (AVNRT) is a predictor of serious block. This study investigated the boundary to avoid fast JR ablation with three-dimensional (3D) electroanatomical mapping in AVNRT patients.Participants were 129 consecutive patients common who received anatomical an antegrade at our institution between August 2013 and March 2019. Successfully ablated sites evaluated terms distances angles left...
Abstract A 7‐year‐old boy presented at our hospital with syncope. At birth, electrocardiography had shown a long QT interval torsade de pointes (TdP). Congenital syndrome (LQTS) been diagnosed by genetic testing, and was successfully controlled oral propranolol. age 7, TdP recurred Electrocardiography revealed prominent T‐wave alternans. The propranolol dose increased, but remained uncontrolled. cardioverter‐defibrillator (ICD) implanted epicardially, completely resolved atrial pacing. We...
Introduction: In Thailand, the efficacy of transvenous lead extractions in patients with cardiac implantable electronic device was limited.Methods: The retrospectively study who received extraction Ramathibodi hospital during 1 January 2006 until 31 December, 2017.Clinical data and ablation procedure were classified.Result: 29 patients, male 48 (72.7%) mean age 57.14 + 19.29 years old, Indication due to infection 34 (51.5%)patients.The treatment 66 (100%) patients.The complication tamponade...
Congenital coronary pulmonary artery fistula (CAF) is rare, and systemic-to-pulmonary (SPAF) even more so. Furthermore, congenital associated with SPAF extremely rare. As far as we know, CAF connected an aneurysm have not been described very often. We 83-year-old woman originating from a to aortopulmonary fistula. Chest radiography revealed shadow at the left edge of heart line. Multi-detector-row computed tomography (MDCT) contrast enhancement cine angiography that was tortuous anterior...
Introduction: 18 year old girl was referred for recurrent palpitations on exertion.Surface ECG revealed pre-excitation syndrome with possible right sided accessory pathway.Electrophysiology (EP) study planned after baseline evaluation.Routine investigations including 2D ECHO normal.Methods: Right femoral vein access achieved.Three catheters were placed in His bundle, Coronary sinus and ventricle.SVT an pathway orthodromic atrioventricular reciprocating tachycardia (AVRT).Ventricular-Atrial...
Abstract Background The subcutaneous implantable cardioverter‐defibrillator (S‐ICD) is recognized as a viable alternative to the transvenous ICD. safety and efficacy of this device has been demonstrated in Western countries, but studies with S‐ICD implantation Japanese patients have not reported. Methods results Twelve received an implant our institute between February September 2016. All S‐ICDs were successfully implanted without complications. One appropriate one inappropriate therapy was...
Long QT syndrome (LQTS) is one of the most common inherited arrhythmias and multiple genes have been reported as causative. Presently, genetic diagnosis for LQTS patients becoming widespread contributing to implementation therapies. However, causative mutations cannot be detected in about 20% patients. To elucidate additional LQTS, we performed deep-sequencing previously 15 85 candidate this disorder 556 Japanese We in-silico filtering sequencing data found 48 novel variants 33 53 cases....
Avoiding excessively fast junctional rhythm (JR) during slow pathway (SP) modification for atrioventricular nodal reentrant tachycardia (AVNRT) helps prevent serious block. This study investigated the usefulness of a predictive ablation point that lies near boundary line between appropriate and JRs with three-dimensional (3D) electroanatomical mapping in AVNRT patients.Participants were 141 consecutive patients common who received anatomical to an antegrade SP at our institution August 2013...
Abstract T wave oversensing (TWOS) is a common cause of inappropriate implantable cardioverter‐defibrillator (ICD) therapies. Various algorithms to avoid ICD therapy are available; however, they not helpful TWOS. Although the reproduction TWOS useful resolve problem TWOS, it sometimes difficult reproduce We report two cases due which were induced only by body twisting. can successfully manage device based on evidence reproduced
Key Teaching Points•Epicardial mapping was done in a patient with sporadic and entirely asymptomatic Brugada syndrome.•Multiple abnormal potentials were recorded on the right ventricle epicardium, especially from below pulmonary artery valve to above tricuspid annulus.•The electrocardiogram normalized after ablation of epicardial potentials. •Epicardial
