Under some conditions, almost all heart tissue is capable of starting a heartbeat automaticityor becoming the “pacemaker,” just like carciaca sinus node.

However, we have not found in the literature studies on the effects of propofol on post-potency-triggered arrhythmias that represent one of the most frequent types of ventricular arrhythmias.
Skip to content Medicine. The septal fascicles of the Left Bundle Branch cause the first wave of ventricular depolarization, in a left-to-right direction across the septum, creating a Q-wave in leads I and II, and an R-wave in lead III. The suspicion that the infusion of this agent eletroifsiologia suppress this type of arrhythmia causes propofol to be deferred as sedative drug in electrophysiological study procedures that aim at the ablation of foci of this arrhythmic disorder.
Hi, Why this article is not access eletrofosiologia allI really need the method but unfortunately I can not use it.
This takes place slowly, and generates a wide wave. Fill out the form below to receive a free trial or learn more about access: Each contraction represents one heartbeat.

Conduction accelerates through the His Bundle into the bundle branches. Analysis of the data presented showed that the infusion of propofol in doses eletgofisiologia by the bispectral index did not seem to interfere in the Expression of ventricular arrhythmias triggered by late post-potentials when these were manifested as ventricular extrasystoles.
Recent studies have demonstrated that this drug exerts effects on the cardiac conduction system having both pro-arrhythmic and antiarrhythmic effects in a concentration-dependent manner.
Located between the Atrium and the Ventricles in the interatrial septum close to the tricuspid valve Receives the impulse from the SA Node and delivers it through the Bundle of His the forefront of the His-Purkinje network Produces rates at BPM if the SA Node fails to fire Conduction through the AV Node is slow, allowing appropriate fill time for the ventricles prior to ventricular contraction. The mechanisms involved in such effects remain poorly defined, but possibly involve ion channels such acrdiaca sodium, calcium, and potassium as well as modulations in the autonomic nervous system.
Ten patients with ventricular outflow tract arrhythmias without structural heart disease were selected and indicated for the treatment of ablation. Programmed Electrical Stimulation in Mice. Figura modificado a partir Mathur et al. An unexpected error occurred.
The atrial depolarization wavefront, represented by the P-wave on the ECG, spreads initially downward in the right atrium, and ends as a primarily leftward vector in the left atrium. These effects seem to be more important when the cardiaxa involved in arrhythmias is hyperautomatism with few effects on reentrant arrhythmias. The objective of this work is to propose a study model for the evaluation of the interference of 2,6-diisopropylphenol in cardiac electrophysiological variables and to analyze the effects of propofol on arrhythmias that conceptually have as a mechanism the activities triggered by late post-potentials.

At baseline and under programmed atrial and ventricular pacing, data were collected from 17 seventeen cardiac electrophysiological variables: Close-up do cateter 1.

These effects seem to be Propofol is an effective hypnotic agent for the induction and maintenance of anesthesia. If the normal conduction pathway is interrupted,another part of the heart takes over as pacemaker. A small portion of the last part of the PR interval is represented by the conduction time through eletrofiisologia bundle of His.
