Talk:Bradycardia

Brachycardia?
Brachycardia? That looks more like a misreading or typo than an alternate name. It means "short heart", which doesn't make sense. -phma 14:47, 7 August 2005 (UTC)

The diving response
Short term bradycardia can also be induced through a nervous reflex called the Diving Response. It is initiated by the immersion of a persons face into cold water. A decrease in heart rate and increase in blood pressure result.

This article my make people with slow heart rates afraid
There are a lot of healthy people with hearth rates below 50 who are not exactly athletes. My resting hearth rate has been below 50 since I first measured it when I was 10 years old. Count Iblis 23:57, 29 October 2006 (UTC)

I agree. It should be made more clear which of the conditions are acute and which can be chronic. Elias (talk) 11:25, 26 October 2021 (UTC)

Wow
I have never heard Bradycardia described in such a negative way. I have a resting heart rate around 50 and my doctor has never shown a bit of concern about this, after reading this article I am worried. —Preceding unsigned comment added by Marshall70 (talk • contribs) 01:22, 11 September 2007 (UTC)

...so what?
This article doesn't really seem to give very detailed reasons as to why having this condition is undesirable. It doesn't give symptoms or problems, and doesn't really say how severe an issue it is if you have it. All it really seems to do is give a name to a condition and scare the crap out of people that think they might have it. —Preceding unsigned comment added by Sgt.

 * I think that is issue highlights the limitations of medical science's knowledge of the range of normality in the normal healthy population. Science is mostly concerned with the unhealthy and to a niche extent the super-healthy athletes.
 * Personally speaking I like to think I'm a normal healthy middle-aged and am proud that I can get my relaxing pulse below 50 without ever being an athlete --86.160.131.91 17:13, 11 November 2007 (UTC)
 * Did you actually read the article? If you do, and this was I presume the version when you made your comment you would have noticed it does actually say why the condition can sometimes be a problem. Specifically "With bradycardia, the first is to address the associated symptoms, such as fatigue, limitations on how much an individual can physically exert, fainting (syncope), dizziness or lightheadedness, or other vague and non-specific symptoms. The other reason to treat bradycardia is if the person's ultimate outcome (prognosis) will be changed or impacted by the bradycardia." While I appreciate reading an article takes time, it's usually best to do it before complaining about said article Nil Einne (talk) 07:44, 23 December 2007 (UTC)

Causes
This section needs rewrite. — Preceding unsigned comment added by 137.43.188.137 (talk) 15:26, 29 February 2012 (UTC)

There are some drugs (medicines) also that cause bradycardia (slow rhythm) such as beta-blockers, which must be mentioned as well

28bpm!
These references seem not reliable to me: first "L'équipe France 2004" is a journal? I know "L'Équipe" is a journal but at Google I only find it at en:WP as a ref; ... can we trust? If pulse rate is 28/min it doesn't mean that heart rate is 28/min. High competition athletes have usually a low HR at rest; under a threshold around 40/min ventricular premature beats are usual - they are not perceived at wrist because the short diastole time before contraction doesn't permit the complete filling of the LV and reduce the stroke volume of the premature beat. So 40/min can be wrongly perceived as 28/min at wrist. Miguel Indurain biography in sp:WP is a featured article it doesn't talk about this heart rate nor does fr:WP and they don't use "L'Équipe" as a ref. Doc Elisa ✉ 19:09, 24 March 2013 (UTC)

Omega 3 oils dropped heart rates 5 bpm. after 4 months. . Could result in bradycardia in some.
O'Keefe JH Jr, Abuissa H, Sastre A, Steinhaus DM, Harris WS.

Effects of omega-3 fatty acids on resting heart rate, heart rate recovery after exercise, and heart rate variability in men with healed myocardial infarctions and depressed ejection fractions.

Am J Cardiol. 2006 Apr 15;97(8):1127-30. Epub 2006 Mar 3.

Heart attack survivors who received 585 mg. of DHA and 225 mg. of EPA for 4-months decreased resting heart rate from a mean of 73 BPM to 68 BPM, which the researchers correlated with increased in vagal activity.

A similar drop of 5 BPM in a trained athlete might drop heart rate in the bradycardia zone. A larger intake in a less-trained person might also drop heart rate.

cholinesterase inhibitors, beta-blockers, digoxin, certain calcium channel blockers, and amiodarone reduce heart rate, and may interact.
Donepezil, rivastigmine, and galantamine reduce heart rate, and can cause bradycardia requiring hospitalization.

Other cholinesterase inhibitors are also likely to cause bradycardia. Other classes of drugs that reduce heart rate include beta-blockers, digoxin, certain calcium channel blockers, and amiodarone. Cholinesterase inhibitors combined with these may exhibit additive effects. http://www.pharmacytimes.com/publications/issue/2011/May2011/Bradycardia-Due-to-Rivastigmine-Drug-Interactions

Absolute sh!t article
How about a simple "bradycardia is a slow heartbeat"? Read the very first paragraph of this utterly useless article as if you didn't know what "bradycardia" means, and tell me if it is actually informative in any way. Wikipedia is FAIL. — Preceding unsigned comment added by 72.16.123.8 (talk) 17:09, 3 April 2014 (UTC)

Relative bradycardia
There is no mention of relative bradycardia, which is mentioned on pages referring to this article. Anybody else see the merit of adding this? — Preceding unsigned comment added by 188.204.65.107 (talk) 16:30, 12 May 2016 (UTC)

Sleeping heart rate
"During sleep, a slow heartbeat with rates around 40–50 BPM is common" Not clear if this means common among normal population or common in bradycardia. Which one should it be? Tombobillabongo (talk) 18:40, 13 July 2018 (UTC)

Avoiding revert war
user:zefr is following me around wikipedia and reverting me. I have asked her to stop this and discuss. The latest revert was a massive one with a simple line that in her opinion my edits were not an improvement. I dispute this and ask for help with this editor. https://en.wikipedia.org/w/index.php?title=Bradycardia&curid=5872&diff=1065519323&oldid=1065506197 Kelly222 (talk) 03:40, 14 January 2022 (UTC)
 * The changes here were not "massive", but rather simple copyedits to improve clarity and remove misinformation - the source used does not say that bradycardia "helps prevent tachycardia during training." That is an unphysiological statement, and is your misunderstanding. No one is following you around. Your writing was being copyedited, and you felt a Google search (edit summary here) was an acceptable source; it is not. Zefr (talk) 04:20, 14 January 2022 (UTC)
 * I was referring to this edit. Please discuss. And please don't post stuff on this talkpage which is related to a different article. https://en.wikipedia.org/w/index.php?title=Bradycardia&type=revision&diff=1065506197&oldid=1065505190 Kelly222 (talk) 06:24, 14 January 2022 (UTC)

Wiki Education assignment: WikiMed UTSW
— Assignment last updated by Ferozemide (talk) 02:19, 27 November 2023 (UTC)

Work plan for WikiMed course
Hello, I am a 4th year medical student working to update this page as part of a WikiMed elective at my school. Over the next few weeks, I hope to overhaul the following areas of this page. I will primarily be pulling sources from Braunwald's Heart Disease 12th edition, and the 2018 AHA/ACC bradycardia and atrioventricular block guidelines.


 * Lead paragraph (12/1)
 * Classification section, including a brief description of the normal physiology of cardiac conduction, and how this allows for classification of bradyarrythmias. (12/6)
 * Expansion of the epidemiology section that should hopefully alleviate concerns discussed in this talk page about asymptomatic bradycardia. (12/11)
 * Overhaul of the management section, especially with regards to the treatment of acute, hemodynamically unstable bradycardia. (12/15)
 * Time permitting, a "Presentation" section would be useful, as the symptoms of intermittent bradycardia are often the cause of referrals to cardiologists.

Please let me know if you have any questions about this work or if you have constructive criticism for me! Thanks. Ferozemide (talk) 00:58, 1 December 2023 (UTC)

UTSW Peer Edit Overall this is a very well written discussion of bradycardia. It is clear that this topic is of great importance to the community. This talk page is incredibly active.

1. I believe that your changes to the first paragraph do a lot to set the tone of the article and clear up common misconceptions. (bradycardia being physiologic in young athletes but less likely physiologic in older adults. The subsequent discussion of symptoms that can be associated with bradycardia is appropriate and further helps outline why bradycardia may be problematic to the patient.

2. Your discussion of normal cardiac conductance is essential to the discussion of bradycardia. Your section does a great job of describing the system in understandable terms. One suggestion I have for this section would be to add an image of the heart with the conduction system labeled. The discussion of sinus bradycardia further clarifies the difference between sinus bradycardia in young athletes vs older adults.

3. A small suggestion, but I believe that the causes section would benefit from being divided under sub headings for cardiac and non cardiac causes.

4. Diagnosis section would benefit from extended discussion of the use of ECG in diagnosis

5. The management section should be expanded to discuss long term management of symptomatic bradycardias

Overall, this is a very info packed, well written discussion. The above editors contributions added significant clarity to the discussion and addressed concerns of individuals within the talk page.

60 vs 50 BPM?
It is commonly taught in medical schools that the normal heart rate range is 60-100 BPM, implying that bradycardia is anything less than 60. However, modern diagnostic criteria for some of these conditions, eg sinus node dysfunction, use a threshold of less than 50. The NIH still appears to use a threshold of 60 on this page, but the ACC/AHA guidelines use 50.

The issue is that "bradycardia" isn't a diagnosis, it's a description of the heart rate being lower than normal range. However this description doesn't really match the diagnostic thresholds used in clinical medicine to make a specific diagnosis. So the first paragraph of the article will be confusing as it seems to reference two different thresholds. Any thoughts User:DocElisa? Ferozemide (talk) 01:23, 1 December 2023 (UTC)
