I enjoy interpreting fast sinus tachycardia like this. People will argue that a rate above xxx is SVT, but one of the discriminators for SVT is a lack of discernable P wave which is clearly present. The T Wave isn't super sharp so that tends to place the Atrial Flutter in the probably not category.

Did you have an epinephrine dump from some sort of adrenal problem?

u/[deleted] 3d ago

Ahhhh I love this response. Yes, I did. I was working an event and got incredibly overwhelmed which isn’t normal for me, but I worked 80 hours that week in 90 degree heat While also unknowingly being Hypokalemic.

I was gonna guess cocaine overdose

u/JFISHER7789 3d ago

Except the p waves thing isn’t really a definitive means of diagnosis for SVT. People can be in SVT and still have p waves. P waves really are only great for discerning between SVT w/ aberrancy and VT.

u/Brofentanyl 2d ago

SVT is a catch all term that means the pacemaker originates above the ventricals but not otherwise specified. Since the P waves are upright, this is clearly originating from the sinus node, this it is Sinus Tachicardia.

2

u/JFISHER7789 2d ago

Sinus tach is technically SVT, by definition, but not used as such. Typically we denote SVT as being >150. And a pacemaker that is still above the ventricular but say close to the AV junction can produce different non-upright waves. And not every upright p-wave denotes sinus pacemaker… my point is that simply the presence of P-waves is not enough to differentiate certain rhythms.

u/Sup_gurl 2d ago

That’s what he is saying, SVT is not a specific rhythm but an umbrella term that describes a nonspecific indeterminate rhythm due to it being so fast that you can’t assess whether there are p waves or irregularity. Specific underlying SVT rhythms can typically not be reliably determined at a rate of >~150 which is why it just gets called SVT. That is not to say that if you can determine the underlying rhythm you would not do so just because you have a rate of >150, that would be backwards logic. That is precisely why we don’t call sinus rhythm SVT when we identify it, even though it is an SVT.

Holy Hypertrophy Batman. Those QRS's are so big they'll make an RN blush.

u/[deleted] 3d ago

Wild right! Echo came back totally normal!

u/LBBB1 3d ago edited 3d ago

Makes sense, I’m glad. There is no left ventricular strain pattern. High voltage can be normal in young adults or people with a thin/athletic build. This is why voltage criteria for LVH usually don’t apply to people below the age of 35 or so.

Wow! Great catch and spot on

u/joeymittens Physician Assistant (PA-S2), Paramedic 15h ago

Are you a thin individual? Sometimes it looks like hypertrophy, when in reality it’s just a thin person with not much tissue to read through. So if appears like large QRS complexes

2

u/Bronzeshadow 3d ago

Waaaaaaaaaaah?!? Alright I'll put my thinking cap half on because it's late and I'm not nearly as drunk as I want to be. Narrow complex @ about 150 or so. P waves look a bit inverted but they're present and uniform so Afib is out. Finally answer SVT. Then again there's that one R-R that's goofy but it's mostly uniform? Fuck it i'd push adenosine and figure it out from there.

11

u/Adorable-Ad6888 3d ago

For a 12 lead with P waves?

1

u/bacongas 2d ago

Kind of would like to know how this pt presents before I pushed adenosine. I’ve seen people vagal out of this by trying to blow the plunger out of a syringe. How was OP looking and feeling is my question and I’m too lazy to read any further down. Some kind of SVT. How far away is the hospital? ABCs? Airway, Breathing, Can you walk to the stretcher?

22

u/TovarichBravo 3d ago

This is what happens when you have way too much caffeine and virtually no potassium. Guaranteed.

Hope you were actually seen for this and didn't just take an EKG at work and let it ride.

13

u/[deleted] 3d ago

You’re exactly right, and oh I was admitted for a day, absolutely

10

u/TovarichBravo 3d ago

Trade out those energy drinks for something that replaced electrolytes. Not sugarade or other bullshit red dye 40 flavored syrups. try LMNT or something similar. Keep hydrated. Kick the caffeine addiction and you'll be surprised how much better you sleep and how little it takes to get up in the morning 💪

u/[deleted] 3d ago

Yeah definitely! I switched to coconut water for the last two months, I feel pretty good overall!

2

u/un_cereal 3d ago

Hey, can you explain what clued you in that OP was hypokalemic?

3

u/TovarichBravo 3d ago

U waves, tall P waves, and what appears to be ST depression in a few spots that don't make sense for an MI. I can't see the measurements but it seems wide for being so fast, that's also another red flag for me.

Inappropriate sinus tach: no discernible etiology or vagal issues.

Appropriate sinus tach: shitty diet, stress

u/[deleted] 3d ago

Hahaha very true

u/cjp584 3d ago

Real answer, 2:1 flutter. You were dead on at like 150 which is a big flag for flutter.

5

u/[deleted] 3d ago

Nope, haha this EKG stumped the cardiologists too. It was so simple, that they literally said “duh” to themselves.

3

u/trollingfordummies 3d ago

150/min is often flutter with 2:1 conduction.

u/lemonsandlimes111 3d ago

lol this was me two months ago, me and my partner both did this on our new lifepak 35 to test out how to do the 12 lead from our normal lifepak 15s. Both had hypertrophy and were like this is broken, 15s read it the same for both us. We’re both 26 🤣

u/[deleted] 3d ago

I’m 28 hahaha

u/Desperate-Dog5109 3d ago

Sinus tach?

1

u/[deleted] 3d ago

Yes, but the cause of the sinus tach.

2

u/[deleted] 3d ago

Answer: HYPOKALEMIA/STRESS

Two Bolus of potassium and 10 hours later my EKG returned to normal..

2

u/Wenckebach2theFuture 3d ago

Hypokalemia shouldn’t cause sinus tach. Could have been stress. But also could have been atrial tach, p wave morphology looks similar to a sinus p wave, so if AT would like be a crista AT.

1

u/[deleted] 3d ago

One would think right? Lol I guess that’s why we call it practicing medicine. New things everyday

1

u/Helassaid 3d ago

A gram or two of caffeine might.

1

u/Wenckebach2theFuture 2d ago

Sure, amongst other arrhythmias too. But if the rate is fixed in place without much variation, should suspect AT.

2

u/harinonfireagain 3d ago

4 Red Bulls, tones dropped, and you’re in the can - I just don’t know why you’re running a twelve lead

Emt b here. You definitely have a heart beat. I'm gonna call for ALS backup.

u/Cyborg-drone-8914 2d ago

SVT with a ton of ischemia I’d say? I’m assuming the rate is too fast to fully perfuse the heart, leading to global ischemia as seen with the numerous ST depressions or something

u/[deleted] 3d ago

I’ll give the answer, your response was well thought out. HYPOKALEMIA believe it or fuckin not. Got two Bolus of potassum over a 10 hour period. EKG returned to normal.

u/12345678dude 3d ago

Myocarditis or a PE?

2

u/[deleted] 3d ago

D-Dimer tested negative, so nope!

u/12345678dude 3d ago

So myocarditis? How was your troponin?

1

u/[deleted] 3d ago

Not myocarditis, troponin was 0.0

u/absurdcigar 3d ago

AV node reentrant tach?

u/[deleted] 3d ago

Nope, but good guess.

u/[deleted] 3d ago

Hint - it’s extremely simple

u/deadaimer 3d ago

Sinus tach with lvh

1

u/[deleted] 3d ago

Sinus tach absolutely, but no LVH. Understate guess because of the QRS complex. But the echo came back with the heart structurally normal.

1

u/adamcost 3d ago

This is my guess also

1

u/largeforever 3d ago

It just looks like V1 and V2 were placed too high.

1

u/squintsp1989 3d ago

SVT@150

u/[deleted] 3d ago

2 rounds of adenosine proved it not to be SVT

u/Imaginary-Emu-2693 3d ago

too much caffeine !

1

u/[deleted] 3d ago

I wish that was the case😂

1

u/Imaginary-Emu-2693 3d ago

aw man, maybe panicking or running?!

1

u/[deleted] 3d ago

Oooo anxiety/panicking was one of the causes, yes. Theres a physiological cause.

2

u/Imaginary-Emu-2693 3d ago

was it a stressful day maybe? i’m not sure lol

u/carpeutah 3d ago

Left ventricular hypertrophy

u/ImNotABot-BEEPBOOP 3d ago

s1q3t3 … right heart strain. you said d-dimer was negative so not likely pe, pneumonia, heavy exercise, pneumothorax, or major trauma. my guess is volume or oxygen depletion. anemia or dehydration?

1

u/[deleted] 3d ago

Hypokalemia/stress!

1

u/[deleted] 3d ago

Oh also, HR =155

u/no-womans-land13 3d ago

Yep that’s some nice heart squiggles

Looks like you’re fine. Maybe you should try drinking more water and being less of a female dog.

u/ChatGPTismyPCP 2d ago

Looks like a 12 lead

u/SpicyPropofologist 2d ago

Also looks like RBBB. Maybe rate dependent? Do you know if your anteroseptal leads have the RSR' pattern at slower rates as well?

3

u/LBBB1 2d ago edited 2d ago

My guess is that the incomplete RBBB isn’t real. It’s from high V1/V2 misplacement. Negative sinus P waves in V1 and V2. Have seen many EKGs with this pattern become normal with standard placement of V1 and V2.

https://litfl.com/misplacement-of-v1-and-v2/

u/[deleted] 2d ago

Spot on

3

u/SpicyPropofologist 2d ago

So, in a properly placed v1 & v2, they sit inferior to the SA node, so the subsequent electrical pathway to the AVN would be towards the properly placed leads, producing a positive (or possibly biphasic) P wave? Because it's negative, though, I can safely discount the RSR' pattern? Or is that overly simplistic? Thank you for the link, BTW. I see a lot of EKGs / strips, and continue to learn as much as I can. Still sometimes a challenge!

1

u/LBBB1 2d ago

That’s exactly it. The sinus P wave is positive when moving towards a lead, and negative when moving away. V1 is placed over the right atrium. It doesn’t make sense for the sinus impulse to move entirely away from V1. This only happens when V1 is placed too high, or when the heart is shifted downwards in severe COPD (extremely hyperinflated lungs). I don’t know of any other causes. Unless the patient has severe COPD, a negative sinus P wave in V1 means that V1 was placed far too high. Very common.

I’m not convinced that the incomplete RBBB pattern means anything. It doesn’t look like a real incomplete RBBB to me. It actually looks like a very specific pattern that is seen with high V1 placement. It’s very easy to give someone this type of pattern with high V1 placement.

u/WeAudiHere 1d ago

What was your PR interval? Looks very close to WPW. PR appears to be right below .12 but also the image isn’t great quality so it could be right at it. Though, I wouldn’t consider that a prominent delta wave.

1

u/Ok-Mechanic1352 8h ago

seems like a v tac but could also just be a fast sinus tach
