Hemodynamics of His bundle pacing

Journal of Electrocardiology, 2017
This review will focus on the feasibility of long term His bundle pacing and its effects on left ventricle (LV) hemodynamics. Compared with right ventricular pacing, His bundle pacing results in a more physiological electro-mechanical activation that contributes to preserve LV function.

Hemodynamics of His Bundle Pacing

Cardiac Electrophysiology Clinics, 2018
In addition to the His bundle, numerous other sites have been evaluated as more physiologic alternatives to pacing at the right ventricular apex. Several hemodynamic studies have shown the benefit of His bundle pacing and septal pacing in comparison with right ventricular apical pacing.

Electrophysiological observations of acute His bundle injury during permanent His bundle pacing

Journal of Electrocardiology, 2016
Permanent His bundle pacing (HBP) is a physiological alternative to right ventricular pacing (RVP). Catheter manipulation during HBP can cause trauma to the His bundle during implantation. We sought to determine acute and long-term incidence of His bundle (HB) injury with HBP.Patients undergoing permanent HBP at Geisinger Wyoming Valley Medical Center ...

Implantation technique of His bundle pacing

Herzschrittmachertherapie + Elektrophysiologie, 2020
His bundle pacing (HBP) preserves physiological ventricular synchrony, with clinical benefits particularly evident when a high percentage of ventricular pacing is required. First experiences with standard leads and manually shaped stylets produced the impression that HBP is highly complex and time-consuming.

His-Bundle Electrography

Postgraduate Medicine, 1974
Intracardiac electrography via a tripolar electrode catheter ascertains the electrical activity of the His bundle and right and left bundle branches. The technique allows precise localization of the site of atrioventricular block.

Enhanced Automaticity of the His Bundle

American Journal of Critical Care, 2005
Scenario: This ECG was obtained in a 70-year-old female patient being treated for new onset atrial fibrillation on the telemetry unit. The patient has been given several doses of digitalis for her atrial fibrillation. Currently the patient is asymptomatic.

Conduction Cardiograph-Bundle of His Detector

IEEE Transactions on Biomedical Engineering, 1975
Heart block is a potential complication in the surgical repair of several congenital cardiac defects. The proximity of the bundle of His to these defects makes their repair particularly hazardous. Earlier workers devised a method for the anatomic localization of portions of the conduction system at the time of cardiotomy. This method is inefficient and

Transvenous Cryoablation of the Bundle of His

Pacing and Clinical Electrophysiology, 1991
Cardiac dysrhythmias are a prominent cause of morbidity and mortality. Pharmacological treatment is ineffective in a large number of patients and is associated with many serious side effects. Thus, direct treatment of cardiac arrhythmias has been used with increasing frequency.

Intra‐His Bundle Block Corresponds with Interruption of the Branching Portion of the His Bundle

Pacing and Clinical Electrophysiology, 1994
We compared His‐bundle electrograms with pathological findings of the atrioventricular conduction system in four patients with complete atrioventricular intra‐His block with narrow QRS complexes on ECG. Split His electrograms were recorded at the time of electrophysiological study.

Clinical Applications of His' Bundle Electrocardiography

JAMA: The Journal of the American Medical Association, 1978
Intracardiac ECG recording and stimulation are useful to evaluate conduction block, bradyarrhythmias, and tachyarrhythmias whose importance or mechanisms are uncertain from a surface ECG in the symptomatic patient. The technique is safe, with only rare complications. The response to medication can be tested during the procedure, helping to maximize the
