Haertig.....nice tracing.... great description and explanation. Still a field medic (going on 28 years-plus 6 for the EMT)(I still remember the first defib).

Haertig, thanks for posting this up.

I just emailed the company - turns out the have a 6 lead option as well. I'm interested to see if I could buy one for use outside the hospital/clinic setting. Unfortunately, only shows the limb leads, but it's still pretty impressive.

I've been contemplating a portable ultrasound too; the combo would do a good screening job for a lot of conditions (all work related purchases, not just a personal EDC)

question for the medics.... Mom had congestive heart failure and threw PVCs... but they were typically preceded by an inverted T wave....which I thought was the normal (T) QRS sequence for a premature ventricular contraction

It is normal for the T-wave to be inverted after a wide QRS complex like a PVC... it is not typical for an inverted T wave on the complex before a PVC unless it was also a wide QRS.

Basically this, though you can get different shapes to PVCs.

Additionally, many things can cause an inverted t wave, independent of a PVC. Think of a PVC as the heart 'hiccuping.' Usually no big deal. The heart can have all sorts of problems. Kind of like you can have have a cold and hiccup - ever have near simultaneous sneeze and hiccup?

Chapstick.
