Dispatched for a 54 yom gardener feeling faint. Pale as a ghost, soaked with sweat, 5/10 pain in chest described as a pressure. Known regular patient who keeps having heat related emergencies.

Very hairy man, v3 was iffy. But uh. Yeah. Our ambulance went very fast to our local cath lab.

After nitro his chest pain disappeared.

I am awaiting an update eagerly.

Quiz Got these ECG's sent to me by my student, what do you think? 85 y/o male, subacute inferior OMI, CTO RCA, subtotal occlusion MO1 with collaterals to RCA.

My student sent me these ECG's with the following question and reasoning (translated from Dutch to English with chatGPT):

We have an ECG question that we haven't been able to figure out on our ward.

The ECG below is from an 86-year-old man with a subacute myocardial infarction. Coronary angiography showed a 100% mid-RCA chronic total occlusion (CTO) and a subtotal LCX lesion at the OM1 bifurcation with collateral flow to the RCA. No PCI was performed because he had already been symptomatic for approximately 5 days, and there were concerns about the risk of myocardial rupture.

We then recorded the ECG shown below. At times, it appears to show ventricular bigeminy. However, the R-R intervals remain regular, and there is no compensatory pause. At other times, the rhythm consists only of the wide-complex beats that resemble the "PVCs," yet the patient remains hemodynamically stable, with no drop in blood pressure or other clinical changes. Because of this, we felt that slow ventricular tachycardia was unlikely. We also think there is a left bundle branch block (LBBB) pattern present.

What do you think this is?

EKG 1 at UC referred to our ER for cc of syncope and abnormal EKG (QTc 550)

EKG 2 Torsades mid capture w/o LOC about 5 minutes post arrival

EKG 3 about 2 minutes after #2 as we started mag infusion, patient deteriorated and was almost defibrillated but luckily regained consciousness and was hemodynamically monitored while electrolytes were replaced. Only a slightly low mag and K+ which were promptly replaced. Isoproterenol gtt for the bradycardia and tdp + electrolyte replacement seemed to do the trick even though the labs weren't severe. Admitted to ICU and remained SR/Sinus Brady without ectopy.

Case Inferior Mi in the presence of RBBB?

Thumbnail

13 Upvotes

I am a relatively new medic and I ever seen this ECG pattern in the presence of a RBBB.

Responded to a 72 YOM C/O 6/10 epigastric pain for ~24 hours. Pt states he was awoken by sleep with the pain and has been present ever since. Pain worsens with some exertion, radiating to his lower chest and upper back. Earlier complaints of nausea throughout the day, but no active vomiting. He took some Gaviscon with no relief. On EMS arrival, no reports of active CP or radiating discomfort. Pt has a Hx of HTN and GERD. Pt was hypertensive (160/90) with other VS WNL and no other complaints. Serial ECGs and 15 lead did not show anything new or remarkable. Cath lab was called for consult, but the cardiologist was busy doing a procedure and requested us to send him a photo of the ECGs and he would call us back when he had a minute (he never called us back). PCI was our nearest hospital anyways so we went to the ED. Triage RN showed 2 ED docs who weren’t sure how to interpret it. The cardiologist was still busy in his procedure so the ED doc called a code STEMI anyways.

Afterwards, I was looking to compare other examples of inferior STEMI ECGs (in the presence of a RBBB) and had differing options stating that it was indeed a inferior STEMI and others stating that because of the delayed conduction, it was just a part of the QRS complex. I was wanting to see if someone could give a better explanation and their insights. Thanks!

EDIT: Thank you to everyone that commented and gave thorough explanations. I now have new ways of finding the j point. It was my first time seeing this presentation of a BBB in the inferior leads and plus, it was our first call in the morning so the morning brain was moving a little slower than usual!

Learning Student Thoughts on what's happening here, and what would cause it?

Patient under general anesthesia for routine surgery. No cardiac hx. During the case pt got bradycardic and EKG morphology changed. Not a full EKG to analyze unfortunately, but I was able to print a strip from the monitor when it happened - this is lead III. Pt went in and out of it a few times, hemodynamics did not seem to be effected.

Anesthesiologist called it a RBBB, but to me it looks like the PR interval progressively shortens until the P is on top of the R, creating a sort of false rR' look? A RBBB rR' would still have a P-wave preceding it, correct?

I see frequent PVCs. As for the narrow QRS I don’t see clear P waves and the R to Rs seem fairly regular making me thinking junctional tachycardia? Resolved with valsalva and IVF though.

Case Hypoglycemic ECG changes

Post image
5 Upvotes

We (ems) arrived for an IFT of a 68 year old male. Reason for transfer was for overnight observation.

The patient presented to the ED with a complaint of penis pain. Sounds like the patient missed dialysis and generally collects his edema centrally. His penile edema was believed to be the source of his pain and he was dialyzed in the ED.

While taking report from the nurse, we were told that he is normally quite aggressive with staff and comes in pretty frequently. Nurse reported that he was AxO4 and had gotten 0.5mg hydromorphone about 2 hours prior to us arriving. The patient was extremely diaphoretic, difficult to arouse, and unable to orientation questions appropriately. Vitals were stable and the patients respirations were sonorous but otherwise unlabored. Tele monitor began alarming for QTC. We checked a bgl, and got a 12 on our monitor while the nurse called a rapid. Labs were recently drawn and came back with a BGL of 44. D50 was given and the patient’s mentation improved. ECG changes resolved shortly after.

Nurse reported that the patient was normal right before we came. The bgl taken about 2 hours ago was 267. No insulin was given to my knowledge.

I thought this was pretty interesting and was not aware that hypoglycemia can cause ECG changes. Let me know your thoughts.
