Acupuncture physicians have studied the application of reflexotherapy to cardiology. However, no one has investigated the connection of ancient Chinese diagnostic methods with modern tools. A total of 102 patients (54 men and 48 women) with heart pathology, namely, sick-sinus syndrome, Wolff-Parkinson-White syndrome, and atrioventricular blockade, were studied using the usual instrumental methods (transesophageal electrophysiological study of the heart, echocardiography), after which they underwent Akabane thermopuncture testing as in traditional Chinese medicine...

The two isomers 6 and 9 of cis(4,4'-)-dicarbomethoxydibenzo-27-crown-9 with tri- and tetra-(ethyleneoxy) linkages transposed were synthesized regiospecifically in high cyclization yields (94 and 92%, respectively) by the Wang-Pederson-Wessels (WPW) protocol and converted via the derived diols 7 and 10 to the corresponding pyridyl cryptands 3 and 4 by reaction with pyridine-2,6-dicarbonyl chloride. As expected from CPK models the cryptand with the tri(ethyleneoxy) arm para to the ester linkages, "short-armed" cryptand 3, did display a higher binding constant (Ka = 2...

BACKGROUND PRKAG2 syndrome diagnosis is already well-defined as Wolff-Parkinson-White syndrome (WPW), ventricular hypertrophy (VH) due to glycogen accumulation, and conduction system disease (CSD). Because of its rarity, there is a lack of literature focused on the treatment. The present study aimed to describe appropriate strategies for the treatment of affected family members with PRKAG2 syndrome with a long follow-up period. CASE REPORT We studied 60 selected individuals from 84 family members (32 males, 53...

INTRODUCTION: Ebstein's anomaly is the most commonly occurring congenital defect associated with the Wolff-Parkinson-White syndrome. In patients with Ebstein's anomaly and supraventricular tachycardia, the absence of right bundle branch block (RBBB) in sinus rhythm is a highly sensitive and specific indicator of the presence of an ipsilateral accessory AP. CASE: We present an electrophysiology case of a patient with Ebstein's anomaly and 3 ipsilateral accessory pathways...

Aims: The long-term outcomes of radiofrequency catheter ablation (RFCA) in patients with Wolff-Parkinson-White syndrome (WPW) remain unclear. We investigated the impact of RFCA on the long-term risk of coronary events and mortality in WPW patients. Methods and results: We conducted a prospective cohort study utilizing the Taiwan National Health Insurance Research Database. Between 2000 and 2003, WPW patients with no prior coronary artery disease (CAD) history, aged over 18 years, who underwent RFCA were identified...

BACKGROUND: Ablation within the aortic cusp is safe and effective in adults. There are little data on aortic cusp ablation in the pediatric literature. We investigated the safety and efficacy of aortic cusp ablation in young patients. METHODS: A retrospective, descriptive study of aortic cusp ablation in five pediatric electrophysiology centers from 2008 to 2014 was performed. All patients <21 years of age who underwent ablation in the aortic cusps were included...

We report a case of a patient with right axillary ventricular. Similar congenital anomaly of the right atrium was reported as "right appendage diverticulum or right atrial diverticulum". However, this independent chamber has its own annulus, synchronizes with the right ventricular, and generates large ventricular potential. Under the guidance of CARTO mapping system, a right atrioventricular accessory pathway associated with Type B Wolff-Parkinson-White syndrome was ablated successfully. This pathway was close to the annulus of the axillary ventricular...

BACKGROUND: Risk stratification for Wolff-Parkinson-White (WPW) pattern either by noninvasive or invasive tests is important to determine whether an ablation is necessary or not. The aim was to compare noninvasive tests and invasive studies in a pediatric WPW population. METHODS: A total of 71 WPW patients (median age 14 years [interquartile range, 11-16 years]; 43 male) underwent Holter monitoring, exercise stress test (EST), and transesophageal electrophysiological study (TEEPS)...

BACKGROUND: The micro waveform of His bundle potential can't be recorded beat-to-beat on surface electrocardiogram yet. We have found that the micro-wavelets before QRS complex may be related to atrioventricular conduction system potentials. This study is to explore the possibility of His bundle potential can be noninvasively recorded on surface electrocardiogram. METHODS: We randomized 65 patients undergoing radiofrequency catheter ablation of paroxysmal superventricular tachycardia (exclude overt Wolff-Parkinson-White syndrome) to receive "conventional electrocardiogram" and "new electrocardiogram" before the procedure...

Purpose The aim of this study was to determine whether the exercise tolerance test can provide diagnostic and prognostic information regarding children and young adults and help predict outcome. METHODS: A total of 87 patients, aged 7-29 years (median 13, mean 13.4) were selected retrospectively. They underwent exercise test at the Freeman Hospital from December, 2015 to May, 2016. There were two groups of patients - 46 had symptoms such as chest pain, palpitations, syncope, or dyspnoea on exertion and no cardiac diagnosis, and 40 patients had a cardiac diagnosis such as hypertrophic cardiomyopathy, transposition of the great arteries with post-arterial switch operation, aortic stenosis or regurgitation, tetralogy of Fallot, abnormal coronary arteries, Wolff-Parkinson-White syndrome, or supraventricular tachycardia...

The delta wave remains an important indicator to diagnose the WPW syndrome. In this paper, a new method of detection of delta wave in an ECG signal is proposed. Firstly, using the continuous wavelet transform, the P wave, the QRS complex and the T wave are detected, then their durations are computed after determination of the boundary location (onsets and offsets of the P, QRS and T waves). Secondly, the PR duration, the QRS duration and the upstroke of the QRS complex are used to determine the presence or absence of the delta wave...

REVIEW
Susan S Kim, Bradley P Knight
For years, conventional wisdom has held that patients with asymptomatic ventricular pre-excitation (asymptomatic WPW or WPW pattern) were at low risk for adverse outcomes. This assumption has been challenged more recently in a number of observational/natural history studies as well as in prospective trials in which patients were more aggressively studied via invasive electrophysiology study (EPS) and more aggressively treated, in some cases, with pre-emptive catheter ablation, despite the lack of symptoms. In sum, the data do not definitively support one approach (early, up-stream EPS and/or ablation) vs...

Muscular septal aneurysms are extremely rare without a ventricular septal defect and are diagnosed accidentally in most cases. Reported cases generally have rhythm disturbance or electrocardiographic findings of Wolf-Parkinson-White (WPW) syndrome. Presently described are 2 cases of ventricular septal aneurysm associated with WPW syndrome, which presented as dilated cardiomyopathy. Pre-excitation disappeared gradually in first patient. There was also concurrent decrease in degree of bulging of the interventricular septum and improvement of left ventricular systolic function...
