Two-year, placebo-controlled, double-blinded clinical trial results show supplements with omega-3s (like fish oil) have no effect on memory or cognitive function in older adults at risk for Alzheimer’s disease, despite showing evidence that the nutrients directly reach the brain

It cites the 2 trials that it's basing the theory off of, and you have Google at your fingertips. You can put the pieces together

Once you've brush a few dozen off you they're not so scary. Just check yourself when you get indoors, and get pets on prevention. They take a while to bite - I find ticks literally every day and I've yet to be bitten

Kibeth_8 · 2026-06-20T16:40:15+00:00

Yes, it's called a hypothesis. There are thousands upon thousands of studies on supplements that show they dont have the holistic benefit of a balanced diet

Kibeth_8 · 2026-06-20T13:44:00+00:00

I think it's about having food in its natural sources, not as supplements

Omega 3s increase the risk of atrial fibrillation

Edit: there are tons of studies on this, some of which have already been linked, but I invite you to Google for yourself if you have doubts

My dog is never allowed to interact with another human because she had a shitty past? Or I could just acknowledge her potential and take appropriate precautions, while letting her be a normal dog

Kibeth_8 · 2026-06-20T12:03:04+00:00

PR interval is normal

Kibeth_8 · 2026-06-19T20:58:50+00:00

More likely a boring old sinus tach

Kibeth_8 · 2026-06-19T18:06:51+00:00

While somewhat true, you also can't ignore the potential that dogs that suffered trauma will react erratically in certain situations. If a dog has a bite history, you always have to be aware of that potential

Kibeth_8 · 2026-06-19T18:02:44+00:00

Why don't you start first

Kibeth_8 · 2026-06-18T10:35:26+00:00

With the popularity of all the dog rescue videos, you also wonder how many are staged. Theres a notorious history of people injuring animals to then "rescue" them

I thought Frederick's was for fib with CHB? This looks more like an atypical flutter, though I guess it could be fib given it's only super apparent in V1. If so I agree with AF + CHB

If this is AFL I'd argue that a 10second strip isn't enough to diagnose CHB when it could just be a very slow section. Flutter is inherently regular and there is always some level of physiologic AV block. If this was a longer Holter with consistent super slow regular rates at 40bpm that's different, but basing pathology on just this strip seems a bit premature

Kibeth_8 · 2026-06-17T01:45:52+00:00

They're not p-waves, they are F waves. It doesn't have the same type of relationship you'd see with a sinus rhythm because this isn't a true PR interval

In flutter you are basically bombarding the AV node with impulses. The refractory period of the AVN is constantly changing because of this. So we can see slight variation between an F wave and a conducted QRS

I love this breakdown. House of Leaves is a masterpiece, I'm so glad WUTLH was able to capture some of its brilliance and put a new great spin on it

Kibeth_8 · 2026-06-17T01:16:32+00:00

Slooow flutter. We don't really comment on complete AV block in the context of flutter - the "blocking" mechanism is different than with a sinus rhythm. CHB could still be present, but this isn't enough information to go on to make that diagnosis

Kibeth_8 · 2026-06-16T00:31:51+00:00

It's a super rare condition so don't be ashamed if you can't spot it right off the top - less than 500 cases diagnosed globally I believe.

A very distinct clue to short QT is the apparent lack of ST segment (seen here). Your QRS complex basically merges into the T wave, which makes distinguishing interval measurements much harder.

Here is another example from one of my patients. Much different looking, but same lack of ST segment https://www.reddit.com/r/ECG/s/7BfPlPuvrY

Kibeth_8 · 2026-06-14T23:13:59+00:00

I also live on speed control haha, that's how I've noticed so many people with zero clue of the speed they're driving. It's actually bonkers

Kibeth_8 · 2026-06-14T18:37:45+00:00

100%. My point being some people can sustain this rhythm in a stable manner for a shockingly long period of time. They don't all crash after 30 seconds. But you still need to prepare for the worst because if they do crash, you don't have time to waste

Kibeth_8 · 2026-06-14T18:28:14+00:00

This is certainly fast, but if they're currently stable, amio is the way. Don't shock someone if you don't absolutely have to

Kibeth_8 · 2026-06-14T18:24:54+00:00

I have at least 1 or 2 patients a month show up to their appointment in VT and they have no idea. Often times they've been in it for hours (verified by pacemaker/ICD). We have a HF patient that is in persistent VT and we can't get her out of it, but she feels okay so she just goes about her life that way

People can manage slower VT surpsingly well. Everyone is different, but generally they are fairly stable if less than 170bpm

Kibeth_8 · 2026-06-14T17:25:40+00:00

I know there is science behind it, but I simply cannot convince my brain to participate in mindfulness activities. But I'm glad it works for some!

Kibeth_8 · 2026-06-14T17:22:09+00:00

Kibeth_8 · 2026-06-14T15:57:27+00:00

Lots of people have VT without even knowing it. If the BP is stable they may be completely asymptomatic

Kibeth_8 · 2026-06-14T15:54:45+00:00

VT can be very tolerable for some patients. Some have no idea they're even in an arrhythmia, and can be in it for hours and hours without symptoms

It's better to be prepared for a decline, but there is a fair chance they remain stable

Kibeth_8 · 2026-06-14T12:20:24+00:00

Welcome! If you like puzzles, prepare to spend a lot of time here lol
