Utilising electroanatomic mapping during ablation in patients with CHD to reduce radiation exposure.
...Published in Cardiology in the young
Patients with CHD can be exposed to high levels of cumulative ionising radiation. Utilisation of electroanatomic mapping during catheter ablation leads to reduced radiation exposure in the general population but has not been well studied in patients with CHD. This study evaluated the radiation sparing benefit of using three-dimensional mapping in p...
Prediction of PR interval prolongation after catheter ablation of incisional atrial tachycardia
...
Published in Journal of Cardiology Cases
A three-dimensional (3D) mapping system is safe and effective for catheter ablation of incisional atrial tachycardia (IAT). Prolongation of the PR interval is occasionally observed after this procedure. Although a first-degree atrioventricular block is typically benign, an excessively prolonged PR interval can indicate a worse prognosis. Currently,...
Postinfarct ventricular tachycardia substrate: Characterization and ablation of conduction channels using ripple mapping...
...Published in Heart rhythm
Conduction channels have been demonstrated within the postinfarct scar and seem to be co-located with the isthmus of ventricular tachycardia (VT). Mapping the local scar potentials (SPs) that define the conduction channels is often hindered by large far-field electrograms generated by healthy myocardium. The purpose of this study was to map conduct...
Catheter mapping and ablation during pregnancy.
Published in Herzschrittmachertherapie & Elektrophysiologie
Eine signifikante Anzahl von Schwangeren erlebt während der Schwangerschaft Herzrhythmusstörungen, die in den meisten Fällen medikamentös behandelt werden. In einigen Fällen erweist sich die Herzrhythmusstörung allerdings als therapierefraktär oder es resultiert ein relevantes Risiko für Mutter und Kind durch hämodynamische Kompromittierung. In den...
Analysis and improvement of the three-column spinal theory
...
Published in BMC Musculoskeletal Disorders
BackgroundDenis and Ferguson et al.’s three-column spinal theory has been widely accepted and applied. However, this three-column theory was proposed based solely on observation and experience without thorough documented data and analysis. The aim of this study was to analyze and improve Denis and Ferguson et al.’s three-column spinal theory to pro...
Three-Dimensional Mapping of Clay and Cation Exchange Capacity of Sandy and Infertile Soil Using EM38 and Inversion Soft...
Published in Sensors (Basel, Switzerland)
Most cultivated upland areas of northeast Thailand are characterized by sandy and infertile soils, which are difficult to improve agriculturally. Information about the clay (%) and cation exchange capacity (CEC—cmol(+)/kg) are required. Because it is expensive to analyse these soil properties, electromagnetic (EM) induction instruments are increasi...
Radio frequency Echo mapping with cellular devices
Published in Scientific Phone Apps and Mobile Devices
In this paper, a method is presented that employs portable cellular devices to perform three-dimensional localization of metallic objects from a set of time-delayed signals. These signals are observed by an array of receiving elements having arbitrary and a priori known distributions in space. Widely used solutions for direction finding are based o...

目的： 探究三维标测下射频消融治疗房室结折返性心动过速（AVNRT）在减少术者X线受照剂量上的优势。 方法： 于2015年1月至2016年6月，选取79例拟行射频消融治疗的AVNRT患者，按随机数字法分入二维标测组（39例）与三维标测组（40例）。二维标测组在X线透视下标测消融靶点，三维标测组利用CARTO 3系统标测消融靶点。比较术中X线透视时间、手术成功率、并发症发生率以及术者X线受照剂量。 结果： 与二维标测组相比，三维标测组患者即刻消融成功率及并发症发生率差异无统计学意义（P>0.05）；与二维标测组相比，三维标测组消融过程X线透视时间及术者X线受照剂量明显减少,差异有统计学意义（P
