81 YOM with Chest Heaviness

It’s approximately 2000 hrs, right as you get comfortable in bed, when you are dispatched to a residence for Chest Pain (CP). You arrive on scene to find an 81 year old male, semifowler’s in bed, complaining of chest heaviness, 8/10, which started 2 hours ago, while in bed, watching tv. The patient also advised he has vomited twice since he called 911 less than ten minutes ago.

He is alert and oriented to person, place, time and event, GCS of 15, denies dyspnea with clear bilateral lung sounds, strong and regular radial pulses, warm to touch, diaphoretic and normal skin color.

Medical history:

  • Hypertension (HTN)
  • MI
  • Hyperlipidemia

Medications:

  • ASA
  • Metoprolol
  • Plavix
  • Pravachol

Vital sings:

  • BP: 160/87 mmHg
  • HR: 96 beats/min
  • RR: 18 breaths/min
  • SPo2: 94 RA
  • BGL: 104 mg/dL

You administer O2 at 2lpm via nasal canula and placed him on your cardiac monitor, then obtain the 12 lead ECG shown below:

  • Doug says:

    Sinus tach (approx 100bpm) with 1st degree block
    ST depression in leads I, AVL, II with significant ST depression in precordials V2-V6
    Right axis deviation with poor R wake progression.
    Suspect a posterior MI, transmit ECG, obtain IV access, administer 162 mg ASA, nitro, antiemetic ( IV gravol), narcotic pain control ( morphine currently). On route posterior ecg V7-V9 with second transmit, serial ecg’s, vials q 5 mins transporting to a PCI facility. Prep for a potential arrest and dysrhythmias (VT).

    With the diffuse ST depressions significant enough to cause ST elevation in aVR, significant L main disease or 3 vessel disease are likely, and could indicate CABG rather than PCI. In a plavix naive patient, I would consider holding off on loading plavix since the patient might need CABG. I’m not sure what I would do in the case of this patient, who is already on plavix.

    1st degree AV block.

    We’ve got ST elevation in the right facing leads (maximal in aVR, some in V1) and ST depression in the left facing leads (I, II, V2-V6) making me think severe 3 vessel disease or proximal LAD or LMCA occlusion but I get very unsure at this point!

    Whichever, it’s not a good ECG to have.

    I would discuss this with the cath lab because I’m unsure how these patients are managed. Do they benefit from bypassing local hospitals to get to PPCI or would they normally be assessed in a local resus room?

Allergies? O2, combivent, Calcium. Repeat 12lead ekg. 2nd set of signs. Depending on 2nd Ekg and 2nd set of signs with combivent, reassessment of patient after interventions. Depending on reassessment, 2nd/3rd VS, and 2nd EKG, would determine my decision on where to transport. Per Massachusetts protocols.

Well I will lean with Dave and go with more education; this is a classic sine wave EKG and with more education hopefully we all could spot this from across the door because again as Dave said this is something rarely seen in EMS if at all; this is the ONE TIME I will advocate…

Looks like sine wave. QRS >.15 tall peaked T waves prolonged PRI, indicative of hyperkalemia. Calcium, bicarbonate, 50% dextrose perhaps even some albuterol, insulin at the Ed

ALS weakness and fall. Mental status is such that he remembers falling. I'm not going to get all excited about this tracing. I'm treating the guy for his complaint and watching him like a hawk during transport. I've seen some aberrant conduction that makes this ECG look like NSR so I'm jaded by experience (need…

It's great to see so many different points of view and styles, it's sad that so many of us are being critical and condescending towards other practitioners. Dave has a point, in that more education is needed, but there is something to be said for everyone who is here, reviewing these case studies and actively…
