Pulseless Electrical Activity

Figure 1

This strip (20 second) is captured during a code. This strip also captured the ff (top to bottom): leads II and V1, SPO2, RR, arterial line (blood pressure-BP), CV2 (central venous pressure-CVP).

The initial part of the strip is showing a wide QRS rhythm and maybe distorted by the (on-going) compression.  At that time, the generated arterial pressure is about 80 mm Hg. The middle black line is the shock delivered. After that is an organized wide QRS rhythm (~15 sec). At the arterial line tracing, the line seemed flat (no BP/pulse). So this wide QRS rhythm after the shock is called pulseless electrical activity (PEA).
