66 year old male CC: Chest pain

Entry Img

Here's an interesting case that illustrates the value of the prehospital 12 lead ECG. A 66 year old male became suddenly ill while playing tennis. Bystanders state that he struck the ball with his racket, staggered a few steps, placed his hand over his chest, and sat down on the tennis court. 9-1-1 was contacted […]

Right ventricular infarction – Part I

Entry Img

Right ventricular infarction. What is it and why should you care? Depending on what you read, right ventricular infarct may complicate up to 40 or 50% of all inferior MIs. Remember, when we say “inferior MI” or “anterior MI” we’re talking about the inferior wall of the left ventricle or the anterior wall of the […]

Rate Related VS. Primary ST-T Changes:
ECG is a rapid atrial fibrilation with ventricular rates approaching 300 beats per minute suggestive of WPW. Widespread ST segment depression is most likely rate related ischemia; elevation in aVR is not a reliable finding with a rapid heart rate point away from LMCA occlusion. Slow the rate before looking for ischemia, injury, or infract.…

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…
