"I wouldn't obsess over any one lead, but the discussion of MCL1 raises a point that I often try to impress on my students and colleagues - that is, don't get fixated on Lead II or any other single lead. I often get students and colleagues…"
"As some have already pointed out, the MCL's were a sometimes valuable asset pre-12 lead cables or if you didn't have a monitor capable of doing the V1. I have been in the situation a few times with a LP10. Yes the vertical, bi-polar view…"
"There isn't, but that doesn't mean that it isn't done. :) I have actually seen the MCL1 label as well, though I don't recall whether it was on the wires themselves or on the monitors, but I didn't just pull that out of my…"
In theory, with a 5th electrode, there's no reason to use a dipole to mimic a precordial lead. With a 3-lead you can only view one lead at a time because the left over lead defaults to the ground lead. That's why you could only…"
It's been a while, but I have seen the 5th (brown) lead that actually was a bipolar lead designed to add MCL1 to the monitor selection. It is a poor substitute for an actual 12 lead ECG with unipolar chest leads, regardless."
"A lot of hospital telemetry packs use 5 leads, and the brown one is supposed to be MCL1--that's about the only place I've seen it. It's essentially useless for any ambulance with an actual 12-lead machine in the back (which is the…"
"This is interesting. I just received correspondence this week from a medical team in Antarctica asking how to "modify a LP10 to obtain a 12-lead ECG". I explained to them how to obtain MCL-1 through MCL-6 and place the LP10 into…"
"I'm not aware of any advantage of MCL1 over V1. My understanding is that MCL1 is primarily an accommodation for a 3-lead monitor to help distinguish VT from SVT with aberrancy and, less importantly, left from right BBB."
"MCL use was like a plague with a million experts. Using a bipolar lead to view a unipolar lead isn't completely acurate but can be useful at least at in showing some evidencfe onf ischemia.
Thing is it became more a case of "let me show…"
I was reading someone's post in an unrelated thread that spoke of a pediatric trauma code waiting 30 minutes for a unit because multiple units were tied up on interfacility non-emergency transfers. It got me thinking about how much I hate them for that reason. Yeah, nobody likes to do them in general, but they make the service alot of money, which is a good thing for equipment, raises, trucks, etc. However, what are the costs of such practices? I've seen services drain all their trucks in one…See More
