Background Balance dysfunction is common in stroke patients. The Berg Scale (BBS) useful for evaluating the balance function of patients, and it can estimate minimal clinically important difference (MCID) balance. BBS scores differ among patients depending on whether they require walking assistance. MCID should thus be estimated separately who assistance those do not.Objectives To individuals have had an early subacute a aid not, to assist clinical determination effectiveness therapy.Methods...
The existence of an atypical fast-slow (F/S) atrioventricular nodal reentrant tachycardia (AVNRT) including a superior (sup) pathway with slow conductive properties and atrial exit near the His bundle has not been confirmed.We studied 6 women 2 men (age, 74 ± 7 years) sup-F/S-AVNRT who underwent successful radiofrequency ablation bundle. Programmed ventricular stimulation induced retrograde conduction over SP earliest activation bundle, mean shortest spike-atrial interval 378 119...
After confirming the measurement properties of Berg Balance Scale (BBS) in patients with stroke by conducting a Rasch analysis, this study sought: (i) to generate keyform as tool for goal-setting and intervention-planning; (ii) determine appropriate strata separating patients' postural balance ability.Methodological analyses cross-sectional data.A pooled sample 156 stroke: mean (standard deviation) age 74.4 (12.9) years.This evaluated BBS's rating scale structure, unidimensionality, accuracy...
Abstract Objective Balance problems are common in patients with stroke, and the Mini-Balance Evaluation Systems Test (Mini-BESTest) is a reliable valid assessment tool for measuring balance function. Determining minimal clinically important difference (MCID) crucial assessing treatment effectiveness. This study aimed to determine MCID of Mini-BESTest early subacute stroke. Methods In this prospective multicenter study, 53 stroke undergoing rehabilitation inpatient units were included. The...
A misdiagnosis of syncope as a seizure can lead to catastrophic outcomes, and thus should be avoided. We herein present the cases two young sisters who experienced transient loss consciousness with convulsions were diagnosed epilepsy. After discovering that their asymptomatic mother had type-2 long QT syndrome (LQT2), it was found younger sister LQT2, while older did not. Although 12-lead ECG showed notched T-waves, QTc interval (422 ms) normal, which precluded diagnosis LQT2. These provide...
Background The Activities-specific Balance Confidence (ABC) scale lacks sufficient psychometric evidence for use in patients with subacute stroke. Objective To investigate the floor and ceiling effects, construct validity, responsiveness, minimal important change (MIC) of ABC Methods cases stroke (n = 62) were analyzed floor/ceiling effects validity at baseline; those 39 responsiveness MIC baseline after 4 weeks. Outcome measures included scale, Mini-Balance Evaluation Systems Test...
The length of the slow pathway (SP-L) in atrioventricular (AV) nodal reentrant tachycardia (NRT) has never been measured clinically. We studied relationship among (a) SP-L, i.e., distance between most proximal His bundle (H) recording and posterior site radiofrequency (RF) delivery associated with a junctional rhythm, (b) Koch’s triangle (Koch-L), (c) conduction time over (SP-T), by AH interval during AVNRT at baseline, (d) H successful ablation (SucABL-L) 26 women 20 men (mean age 64.6 ±...
Purpose The physical function of older patients with heart failure (HF) is likely to decline, and the Short Physical Performance Battery (SPPB) widely used for its evaluation. No study has analyzed SPPB by using Rasch model in these patients. aim this was examine structural validity item response inpatients HF.Materials methods In multicenter cross-sectional study, we investigated 106 HF. We evaluated SPPB's rating scale structure, unidimensionality, measurement accuracy (0 = poor...
To identify the Berg Balance Scale (BBS) values that can be used to discriminate use of a walking aid and BBS sub-items reveal differences in aids among hospitalized older adults with hip fracture.The cases 77 (age 80.8 ± 7.5 years) fracture who were able walk independently hospital retrospectively analyzed. A receiver operating characteristic curve (AUC) analysis was scores optimized identification subjects different levels aids. The identifying differing identified by classification...
An 81-year-old man with long RP narrow QRS tachycardia underwent catheter ablation. Ventricular pacing reset the atrial cycle over a retrograde slow pathway, followed by termination of without capture, confirming diagnosis fast-slow atrioventricular nodal reentrant (AVNRT). The earliest activation during was found in noncoronary sinus Valsalva, where first delivery radiofrequency energy terminated and eliminated inducibility tachycardia, conduction block pathway. This is report AVNRT,...
The aim of the current study was to identify a cut-off value for predicting walking independence at discharge in older adults with hip fracture based on their Berg Balance Scale (BBS) score admission convalescent rehabilitation ward.This retrospective, multicenter, observational 187 fractures (mean age 83.7, range 66-97 years). Data collected patients' age, sex, treatment, and physical function evaluation. An ordinal logistic regression analysis used predictors associated degree discharge....
Objectives: The Berg Balance Scale (BBS) is a core measure of balance function in patients with stroke. Latent rank theory (LRT) statistical method that enables the degree functional impairment to be ranked from sub-items rating scale; each can then characterized. Identification characteristics by would beneficial for interventions improve This study aims use LRT and characterize stroke impairment. Methods: was multicenter retrospective analysis 293 subacute We used BBS estimate optimal...
Cardiac ryanodine receptor (RyR2) gain-of-function mutations cause catecholaminergic polymorphic ventricular tachycardia (CPVT). Conversely, RyR2 loss-of-function a new disease entity, termed calcium release deficiency syndrome (CRDS), which may include RYR2-related long QT (LQTS). Importantly, unlike CPVT, patients with CRDS do not always exhibit exercise- or epinephrine-induced arrhythmias, precludes diagnosis of CRDS. Here we report boy and his father, who both experienced...
This atypical atrial resetting with ventricular extrastimulus delivered during supraventricular tachycardia is characterized by no capture of local deflection contralateral to the earliest site and a finding unmasking presence nodoventricular pathway, insertion which located apically, away from mitral annulus.
Abstract Introduction Electrophysiological properties of reentry circuits fast‐slow atrioventricular nodal reentrant tachycardia (F/S‐AVNRT) may contribute to cyclic variability after atrial induction. Methods In 156 inductions 33 patients with F/S‐AVNRT, we measured the atrio‐His (AH) and His‐atrial (HA) intervals in first cycle induction (AH[1] HA[1], respectively), those second (AH [2] HA [2], during that maintained a stable length AH[T] HA[T], calculated value AH(1) minus AH(T) [ΔAH]...
The epinephrine infusion test (EIT) typically induces marked QT prolongation in LQT1, but not LQT3, while the efficacy of β-blocker therapy is established LQT3. We encountered an LQT3 family, with SCN5A V1667I mutation, that exhibited epinephrine-induced prolongation.Wild-type (WT) or V1667I-SCN5A was transiently expressed into tsA-201 cells, and whole-cell sodium currents (INa ) were recorded using patch-clamp techniques. To mimic effects epinephrine, INa after application protein kinase A...

There no known MCID for Berg Balance Scale (BBS), which measures balance function patients with hip fractures. We aimed calculate of BBS older adults fractures.Materials and methods This a retrospective multicenter clinical study that included 187 was calculated using functional ambulation categories (FACs), were used anchors change scores between admission...
Purpose The physical function of older adults age ≥ 75 years hospitalized for cardiovascular disease (CVD) often decrease. Minimal Clinically Important Difference (MCID) is the smallest clinically meaningful difference due to therapy. Short Physical Performance Battery (SPPB) and Comfortable Walking Speed (CWS) are evaluations commonly used in people with CVD. This study aims clarify MCIDs SPPB CWS old-old adult CVD.Materials methods was a multicenter, prospective 58 acute CVD...
