tachycardia

Pause if you need to.

The correct answer is B. Tachycardia shortens diastole and increases the left atrial pressure.

In mitral stenosis, this decreases the amount of time the left atrium has to try to push that blood through the stenotic valve into the left ventricle, right? This often raises the left atrial pressure and decreases the amount of left ventricular filling.

All right, last but not least, a patient with severe mitral stenosis develops atrial fibrillation with rapid ventricular response and flash pulmonary edema.

Initially was hypotensive when came into the ED and was diagnosed with a PE.

Tachycardic with systolics and heart rate in 120s, hypotensive with systolics initially in 80s.

Gets 500 cc of fluid and systolics perk up to 120s, diastolic up to 70s.

Troponin is 36 and 33 on high-sensitivity troponin T assay.

That recognition relies entirely on your calm observation skills under pressure, looking for the rash, listening for the wheeze and checking the heart rate.

Tachycardia, a fast, weak pulse points heavily toward an allergy or shock.

Bradycardia, a slow bounding pulse points heavily toward a vasovagal response.

Now, regardless of how the scenario ends, whether it was a mild itch that you stopped early, a full anaphylactic shock that required a code team, or a vasovagal swoon that resolved with leg elevation, the source material highlights a critical final administrative step, post-reaction documentation.

I wonder what that could be.

Tachycardia, you know, fast heartbeat, and EKG changes.

You know, when we go back and look at this, We've had certain terms that pharmaceutical companies have educated us about, haven't they? Certain things have become household words.

Things like myocarditis and pericarditis.

And this pathological process is responsible for the earlier signs of malignant hyperthermia, which are tachycardia, hypercapnia, and muscle rigidity.

And this can vary from patient to patient, but that's kind of that classic triad of early signs.

Tachycardia, hypercapnia, or elevated CO2 levels, and muscle rigidity.

So once the energy stores are depleted

depletedThe muscle cells start to break down, basically rhabdomyolysis.

These range from harmless and barely noticeable to immediately life-threatening.

Tachycardia refers to a heart rate that is too fast, generally above 100 beats per minute at rest.

Bradycardia refers to a heart rate that is too slow, generally below 60 beats per minute, though this can be perfectly normal in well-trained athletes.

Atrial fibrillation is one of the most common arrhythmias, in which the atria quiver irregularly instead of contracting in a coordinated fashion.

have to hear, yeah, so that's one of the contraindications.

Most of the patients that we see for IV sedations, which is nice for us, are a little nervous, right? So maybe their heart rate generally is a little higher, which is great for Presidex because I don't usually give it if their heart rate is in the low 60s because you will get bradycardia with it, right? and it's a you know it's an alpha agonist so you're going to get bradycardia you can get some hypotension with it so if they're already starting out and they're a really good athlete and they're in like in the 50s heart rate i'm like oh man i can't use presidex like go in the room like you should be nervous i don't tell them like you know you should be like tachycardic in the 120s you know um that's great for presidex like the marijuana users redheads like it's great for presidex

yeah

because a lot of times they're tachycardic or they're really nervous patients and The older I get, I'm seeing more and more patients that are nervous and I think, My own thought is helicopter parents, depending what area you're working in, the kids aren't as tough as they used to be in the 80s or whatever.

So I feel like that's more and more a thing.

But either way, if they're in the 60s and above, I like to use Presidex.

but so it's not a lot.

It's, it's great.
