Aminophylline and beta-adrenergic agonists are widely used in the treatment of obstructive lung diseases. It has been suggested that combined aminophylline and beta-agonist therapy may promote the development of atrial and ventricular arrhythmias. The effects of these agents in combination on myocardial conduction and tissue refractoriness have not been by: 6.

They described the pre-potential to be similar to that recorded between the His bundle and ventricular electrogram by electrodes in the His bundle area. In support of the dead-end tract theory was the finding that the potential, seemingly originating from the normal conduction system, was recorded just beneath the successful ablation site [ ].Cited by: 4. disk system, if known, would be appreciated.

Normal excitation originates in the sinoatrial node and then propagates through both atria (internodal tracts shown as dashed lines).The atrial depolarization spreads to the atrioventricular node and passes through the bundle of His (not labeled) and then to the Purkinje fibers which make up the left and right bundle branches; subsequently all Cited by: Abstract.
Orderly contractions of the atria and ventricles are regulated by the transmission of electrical impulses that pass through modified cardiac muscle cells (the cardiac conduction system) interposed within the contractile by: Joseph Feher, in Quantitative Human Physiology (Second Edition), The bundle of His and its Branches Conduct the Impulse to the Apex of the Heart.
The bundle of His consists of wide, fast-conducting muscle fibers that carry the cardiac impulse through the insulating annulus fibrosus into the fibrous upper part of the ventricular septum. There, it becomes the left bundle branch and the. His bundle pacing in humans was first described in by Narula et al.
1 They demonstrated that it was possible to stimulate the His bundle to produce normal physiological ventricular activation via the His-Purkinje system.
However, the first report of permanent His bundle pacing, by Deshmukh et al., did not occur until 2 In that study, His pacing was performed in a series of Cited by: 8. Wilhelm His Jr. described the physical link electrically bridging the atria and ventricles of the heart in  The specialized muscle bundle connecting the atrial and ventricular chambers of the heart is now known as the bundle of His. The bundle of His quickly transmits the electrical impulse from the atrioventricular (AV) node to the left and right bundle branches and into the Author: Cyril Patra, Mark F.
Brady. Recording cardiac electrical potentials from the region of the bundle of His in the awake, nonsedated animal would allow a more physiologic evaluation of impulse transmission through the.
He pioneered studies in cardiac conduction and coined the term ‘heart block.’ 32 InWenckebach described the phenomenon that later bore his name.

The cardiac bundle of His and right and left bundle branches are an essential ventricular component of the AV conduction axis (Figures).
26 These cells, surrounded by a defined fibrous matrix serve to transmit AV activation to the ventricular myocardium. The organizational architecture of the system has evolved to precisely synchronize. Author(s): Roberts,Nigel K(Nigel Keith) Title(s): The cardiac conducting system and the His bundle electrogram.

Electrocardiography is the process of producing an electrocardiogram (ECG or EKG).It is a graph of voltage versus time of the electrical activity of the heart using electrodes placed on the skin.
These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle (heartbeat).MedlinePlus: Roberts NK, Gelband H. eds. Cardiac Arrhythmias in the Neonate, Infant, and Child.

Coupling interval (Sl-S~) is msec. S-H interval is msec, and H-V interval is prolonged to msec. A' is atrial premature beat conducted to His bundle and blocked below it. Beats 4 to 9 are reentrant ventricular tachycardia.
HB, His-bundle electrogram. Different areas of the PR- interval. ADA = high right atrium. EHH = His bundle interval electrogram. PA = From the high right atrium to the beginning of the P wave in the ECG to the first fast deflection of the lower right atrium; this represents the right intra-atrial conduction, its normal value ranges are between 30 and 50 ms.
