Hoe werkt Isoprenaline?
Aangrijpen van isoprenaline op de β1-receptor veroorzaakt een toename van de hartfrequentie (positief chronotroop effect) en het slagvolume (positief inotroop effect), waardoor het hartminuutvolume toeneemt, en een toename van de geleidingssnelheid (positief dromotroop effect) waardoor de refractaire periode van het …
How is atropine used to treat bradycardia?
Atropine is the first-line therapy (Class IIa) for symptomatic bradycardia in the absence of reversible causes. Treatments for bradydysrhythmias are indicated when there is a structural disease of the infra-nodal system or if the heart rate is less than 50 beats/min with unstable vital signs.
What is the maximum dose of atropine for bradycardia?
The recommended atropine dose for bradycardia is 0.5 mg IV every 3 to 5 minutes to a maximum total dose of 3 mg. Doses of atropine sulfate of <0.5 mg may paradoxically result in further slowing of the heart rate. 8 Atropine administration should not delay implementation of external pacing for patients with poor perfusion.
How effective is atropine as a first-line treatment for unstable patients?
Atropine is traditionally the 1st-line medical therapy. However, for very unstable patients, epinephrine is more reliably effective and may be preferable. Start at 1 mg atropine, additional doses can be given to a maximal dose of ~3 mg. 9 Don’t give atropine, sit back, and expect that it will fix everything.
