Peer Review Suggestions

Hello! I’ve reviewed the Lead, Medical Uses, Types, and Interface with Person sections of this article for the UCSF Wikipedia Elective. Overall, great work revising this article. Here are some suggestions:

Lead: great expansion of content and references in a simple, easy-to-follow manner

Medical uses: I like the revisions you made to the content and references about outcomes, but I think the first few sentences could be improved for readability

Types: Additional need for references in “manual external defibrillator” section, but good content revisions overall. Good simplification of “manual internal defibrillator” section. “AED” section is a little long. Especially because there is a link to an external article. I might consider cutting down this section, especially the 4th and 5th paragraphs. “Wearable cardiac defibrillator” references “as of February 2011”, which is quite a bit out of date now.

Interface with person: Would add references to this section. Could add a picture of self-adhesive electrodes. Could add a picture for the anterior-posterior scheme. Also should label the current image as anterior-apex scheme.

Hope this is helpful--let me know if you have any questions!

Query Trivia Section

It notes "This changed in 1990 after Australian media mogul Kerry Packer had a heart attack and, purely by chance, the ambulance that responded to the call carried a defibrillator." But a defibrillator is used for Cardiac Arrest NOT Heart Attack. Did he have a Heart Attack which ledt to a Cardiac Arrest? — Preceding unsigned comment added by 109.158.59.137 (talk) 08:18, 17 September 2018 (UTC)

Energy only relates to damage, not to shock strength of defibrillation or cardioversion.

Experiments and research have since a long time established that energy is not a reliable parameter to determine the shock strength. It should be inserted in the article as it gives a better perspective on the relevant mechanisms. 84.58.249.189 (talk) 10:50, 22 July 2023 (UTC)

Please read IEC 60479-1 and 2. The stimulus amplitude increases with charge, not energy. 84.58.249.189 (talk) 09:58, 26 July 2023 (UTC)

Valid point, but I am failing to see how the IEC standard works as a source for this article. (Part of that is because I am failing to see the full text, hah.) Maybe someone will find a more fitting and hopefully more accessible source. Artoria2e5 🌉 08:43, 29 May 2024 (UTC)

Electrical aspects

There is no mention of how a defibrillator generates the desired shock; that’s also a kind of "mechanism", but one that’s understood by humans. There seems to be at least two main "waveforms" that manufacturers aim to provide, the older monophasic and the newer biphasic.

I’m not sure whether the engineering aspect of a medical device requires a medical source. Well, the part that compares the therapeutic efficacy of different waveforms definitely will require one, if I get to writing it… eventually. Artoria2e5 🌉 06:51, 29 May 2024 (UTC)
