The early repolarization experiment

Entry Img

Any paramedic who has studied the STEMI mimics has heard of the classic benign early repolarization pattern of a "fish-hooked" J-point with upwardly concave (smiley-faced) ST-segment, often best appreciated in lead V4. But, as the excellent work of Stephen Smith, M.D. demonstrates, not all cases of early repolarization present this way, and it can often […]

Left ventricular aneurysm vs. acute anterior STEMI

Entry Img

Some of you expressed concerns about the possibility of the ECG abnormality we sometimes refer to as left ventricular aneurysm (persistent ST-elevation after previous MI).

Excessive discordance as a marker of acute STEMI in LBBB

Positively deflected QRS complexes can be expected to show ST-depression and inverted T-waves.

Discordant ST-Segment Elevation in LBBB or Paced Rhythm

Entry Img

If you’ve been following the Prehospital 12-Lead ECG blog for a while, you know that I’m advocate of using Sgarbossa’s criteria to help identify acute STEMI in the presence of left bundle branch block (LBBB) or paced rhythm. According the Sgarbossa’s original criteria, 5 mm of discordant ST-segment elevation is required to identify AMI in […]

Axis Determination – Part VI
This is a great discussion of axis determination. One minor suggestion: I think it's potentially misleading to refer to an axis between 0 and -30 as "physiologic left axis deviation", since "axis devitation" implies deviation from normal, and axes between 0 and -30 are perfectly normal, (depending on age and body habitus). It may be…

Right ventricular infarction – Part I
Can you give me a little more info on hypervagotonia? I googled around for some info but there doesn't seem to be much info and it's a term I've never heard before. Thanks!

68 y.o. male with weakness: “Treat the monitor, not the patient?”
Destination: ED with most to offer. He's 68 and weak. I'm in Florida...we have people with their favorite Dx on their car tags around here, so that doesn't bother me. Neither does diminished lungs. Altered mental status does. And the ECG looks like an old oscilloscope...which I've used in the field (MRL)...which tells me high…
