Techniques of Bedside Pacing [PDF]

open access: yes, 1971
In temporary pacing the primary approach is transvenous--either percutaneous or via a cutdown in the jugular or brachial vein system. Tripolar and quadripolar pacemaker catheters which have been used for His bundle recordings are now obtainable as well ...

Long-term performance and risk factors analysis after permanent His-bundle pacing and atrioventricular node ablation in patients with atrial fibrillation and heart failure.

open access: yesEuropace, 2020
AIMS His-bundle pacing (HBP) combined with atrioventricular node (AVN) ablation has been demonstrated to be effective in patients with atrial fibrillation (AF) and heart failure (HF) during medium-term follow-up and there are limited data on the risk ...

Ultrahigh‐Yield, Multifunctional, and High‐Performance Organic Memory for Seamless In‐Sensor Computing Operation

open access: yesAdvanced Functional Materials, EarlyView.
Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...

Radiofrequency Catheter Ablation of Atrioventricular Nodal Reentrant Tachycardia: It Is Not Always As It Is Expected [PDF]

open access: yes, 2004
Observation of Coincident arrhythmias is not uncommon but the co-existence of idiopathic verapamil sensitive left ventricular tachycardia (ILVT) with other arrhythmias is very rare.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Recent approaches to His-Purkinje system pacing

open access: yesChinese Medical Journal, 2019
. Objective:. Physiologic cardiac pacing is a novel technique which has been largely popularized in recent decades. His bundle pacing (HBP) has been long considered the most physiologic pacing method; however, with the widespread implementation of this ...

Transient unexpected improvement of AV conduction: What is the mechanism? [PDF]

open access: yes, 2006
This ECG was recorded from a 93 year old patient with a previously documented third degree AV block and an underlying LBBB. The twelve lead ECG demonstrates sinus bradycardia at a rate of 52 beats per minute, a PR interval of 230 milliseconds, and a ...

Mapping and Ablating Ventricular Premature Contractions That Trigger Ventricular Fibrillation: Trigger Elimination and Substrate Modification [PDF]

open access: yes, 2014
Ventricular fibrillation (VF) is a malignant arrhythmia, usually initiated by a ventricular premature contraction (VPC) during the vulnerable period of cardiac repolarization. Ablation therapy for VF has been described and increasingly reported.

CLINICAL USE OF HIS BUNDLE PACING

open access: yesNihon 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 ...
