CLINICAL USE OF HIS BUNDLE PACING

Nihon Naika Gakkai Zasshi, 1976
His束心電図記録に際して重要なことは, His東電位(H)のvalidationである.とくにHis-Purkinje系の伝導時間(HV)の定量的測定にはHのvalidationが必須である. Hのvalidationの方法としてHis束ペーシングが有用である. HとRB (右脚電位)の鑑別, His束内プロック時のH′(distal H)とRBの鑑別にはHis束ペーシングが有力である.われわれは左軸偏位を伴う右脚ブロック(RBBB+LAD)4例,房室ブロック6例, His束内ブロック1例, Wolff-Parkinson-White (WPW)症候群8例を含む30例でHis束心電図記録と同時にHis束ペーシングを行ない,その有用性を確認した.正常者群ではHis束ペーシング中 ...

Amido‐Amine Co(II) Precursor‐Based Atomic/Molecular Layer Deposition Processes for Cobalt‐Organic Thin Films and Their Thermal Conversion to CoO Thin Films

Advanced Materials Technologies, EarlyView.
Three new atomic/molecular layer deposition processes are developed for Co‐organic thin films using a promising all‐nitrogen‐coordinated cobalt precursor. The study examines film growth, reaction mechanisms, chemical stability, and decomposition pathways of the resulting films through extensive characterization techniques and DFT calculations ...

Toward Wireless Implantable Robotic Systems Driven by Magnetic Field for Personalized Therapy

Advanced Robotics Research, EarlyView.
Robotic materials are playing an increasingly vital role in enabling sensing and actuation at small scales. This perspective highlights recent advances in magnetic materials and magnetically actuated devices for wireless sensing, actuation, and energy harvesting toward implantable robotic systems for closed‐loop therapy.

The Evolution of Sinoatrial Node Function in Man [PDF]

, 1973
The function of the sinoatrial node is complex. In nearly all hearts, this small bit of tissue is responsible for spontaneously generating the impulse which will be distributed to the remainder of the heart, maintaining coordinated electrical and ...

Purkinje Arrhythmia Origin Made Easy [PDF]

, 2017
Tachycardia originating from the fascicles or His-Purkinje 1 system includes a wide spectrum of arrhythmias such as ventricular fibrillation (VF) and ventricular tachycardia (VT) which could be monomorphic or polymorphic with various substrates ...

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

Advanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Peri‐left bundle branch pacing after atrioventricular node ablation and failed his bundle pacing in atrial fibrillation

Journal of Arrhythmia, 2020
We described a case where peri‐left bundle branch pacing (PLBP) may become an alternative approach in difficult His bundle pacing (HBP) following atrioventricular nodal ablation in a patient with atrial fibrillation. After atrioventricular nodal ablation,
