Two hemodynamic cardiac tracings are shown here: a left ventricular pressure tracing and a pulmonary capillary wedge pressure. An important finding can be found in the tracings. What is the finding, and what diagnosis does it suggest?

You find this tracing in a stack of 12-leads and a colleague states, "Oh yeah, that was from a post-cardiac arrest case we worked earlier, but he ended up coding again in the department." What's going on with this crazy tracing? For bonus points, can you suggest a cause of the cardiac arrest based on what you see here?](https://app.figure1.com/case-detail/00c680bf-3b67-46ff-9abc-fe0b032ae8dd)
