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

Transverse Dissociation of the Human His Bundle

Pacing and Clinical Electrophysiology, 1982
“Completed” and “abor tive” alternating Wenckebach periods occurred in a symptomatic female with calcification of the mi tral annulus, These arrhythmias were attributed to transverse dissociation of the His bundle into two horizontal levels “connected in series,” with 2:1 block in the “distal” level and Wenckebach periods in the “proximal” level. Intra‐

Detection of his bundle potentials

1989
Conducting system potentials were first recovered from the body surface in dogs in 1973 using a sequence of high-gain amplification and filtering followed by digital signal averaging. Subsequent application of similar methods to man by more than 18 research groups world-wide have shown it feasible to record His Purkinje signals non-invasively in about ...
