I have seen 2 rhythm types on the natural course of dying (peacefully). In the first, the heart rate holds for a few hours (AF or sinus) then gradually declines and the latent pacemaker kick-in one-by-one (junctional to ventricle). The other one is the one I'll post here. So this is not the sudden cardiac death (SCD) where people get excited.
These are 5 strips (~ 4 minutes duration) captured in a DNR pt. Pt was in no distress during the whole process.
Pls note timestamp on the upper left part of the strip.
Image 1
The rhythm is regular and narrow with ST changes.The latter part of the strip shows wide QRS rhythm most likely AIVR.
Image 2
Few seconds later, it turned into a fast wide QRS rhythm (likely VT)
Image 3
About 7 second later, change in morphology is seen (best seen in II, aVF and aVL)
Image 4
About 2 minute later, looked like the QRS voltages becomes smaller and the rate becomes slower (agonal rhythm).
Image 5
About 4 minutes after, asystole can be observed.
