The 360 Degree Heart – Part I

Entry Img

The hexaxial reference system. If I asked you to imagine how the limb leads “look” at the heart, you would probably picture something like the image below: Notice those gaps in the limb leads? They don’t really exist. They’re an illusion. This isn’t something that is commonly emphasized when the cardiac axis is being taught, […]

Conclusion: “And then I gave her a NTG…”

Entry Img

Recap: From  Part 1: A 64 y.o. woman with typical symptoms of ACS was given nitroglycerin by the paramedic. Her ECG: ECG Interpretation: As noted by many of our astute readers, there is obvious ST-segment elevation (STE) in leads III and aVF. Lead II doesn’t show much STE, but relative to the small R wave […]

64 y.o. Female with CP – “And then I gave her a NTG…”

Entry Img

My apologies for the faded ECGs. Turns out the medic (a recent grad from our hospital’s program) had been carrying them in his work pants for over a week, waiting to catch me in the ED. The  patient had been brought to another hospital, but he wanted to review the ECGs with me. They had […]

“Bad heartburn” – Conclusion

Entry Img

Recap In “Bad Heartburn” – 82 y.o. female without chest pain, the paramedic had obtained an ECG on an elderly woman who only complained of mild “heartburn.” An initial ECG was obtained: ECG interpretation : The degree of ST elevation is significantly higher in lead II than lead II, which usually supports an RCA occlusion. […]

“Bad heartburn” – 82 y.o. female without chest pain.

Entry Img

This case is courtesy of paramedic Jason Cameron, who works for Stratford EMS in Connecticut. The ALS unit had been dispatched for an older female with “chest pain.” Upon arrival, however, the 80 y.o. patient denied any pain or pressure, and only endorsed some mild “heartburn,” localized to the epigastrium, non-radiating, and rated it at […]

Conclusion: 38 Year Old Male – Chest Pain and Leg Paralysis.

Entry Img

Recap In the post yesterday , the paramedic crew was evaluating a 38 y.o. male who had sudden, severe chest pain, as well as leg numbness and paralysis, and whose vital signs showed a mild bradycardia and pronounced hypertension. The ECG obtained by EMS appears to be junctional, with an unclear contribution from the SA […]

Rate Related VS. Primary ST-T Changes:
Also forgot to mention decrease the FiO2, 3LPM is getting us a SpO2 of 98%, titrate down so we staying at or above 94%. No need to hyperoxygenate & create all those fun free radicals. I would also include using an EtCO2 nasal cannula, lets get another measure of our cardiac output.

Rate Related VS. Primary ST-T Changes:
Atrial Fibrillation w/ Rapid Ventricular Response. There appears to be possible Delta Waves, the most prominent being in aVL, also leads I, II, and V6. In the EMS 12-Lead there appears to be a fusion beat, 3rd in V2, slurred R-wave appears quite consistent with a Delta wave. I would consider WPW as the primary…

Rate Related VS. Primary ST-T Changes:
Afib. There is widespread depression in most leads and aVR has some elevation...but I am skeptical about this ecg. If a quick fluid challenge of 500-1000cc did not slow down the HR I would give him some diltiazem (5mg increments is our protocol or 0.25mg/kg) and slow the rate down a bit and see if…

Rate Related VS. Primary ST-T Changes:
Isolated ST elevation in AVR with ST depression in several leads. Rapid, irregular rate suggests AFIB with RVR. I would provide entry note with this exact description and leave it to hospital whether or not to activate cath lab. My EMS treatment: IV access, 324 mg. ASA, NTG, Cardizem .25 mg/kg over 2 minutes, consider…

Rate Related VS. Primary ST-T Changes:
AF with RVR @167, LVH and prolonged QT. ST depression to I,II and V3-6 and reciprocal elevation to aVR equal to or >1mm highly suggestive of LMCA or 3-vessel disease. High specificity for proximal occlusion. Aspirin, GTN, IV access, Spo2 >95%, Transport to nearest PCI/Cath Lab facility ASAP
