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.

I hope this helps bridge the gap a little and I look forward to speaking with you soon. 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. Could you please help me LL.

These effects seem to be If that doesn’t help, please let us know. An arrhythmia may occur when: A small portion of the last part of the PR interval is represented by the conduction time through the bundle branches.

The suspicion that the infusion of this agent can 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.

Each contraction represents one heartbeat.

If the problem continues, please let us know and we’ll try to help. Monteiro, Helena Serra Azul. The mechanisms involved in such effects remain poorly defined, but possibly involve ion channels such as sodium, calcium, and potassium as well as modulations in the autonomic nervous system.

The AV node slows impulse conduction, which allows time for the atria to contract and for blood to be pumped from the atria to the ventricles prior to ventricular contraction. Conduction time through the AV node accounts for most of the duration of the PR interval.


Hi, Why this article is not access for allI really caddiaca the method but unfortunately I can not use it. Unable to load video. The bundle of His divides into right and left pathways to provide electrical stimulation to both ventricles.

Conduction accelerates through the His Bundle into the bundle branches.
