Ich denke, ich habe eine koronarie

I get into the office today to literally hundreds of emails and missed calls. My heart is pounding trying to process what is going on. My assistant sent the draft over to the clients before we had a chance to correct changes and everything just blew up! Now I'm trying to get on top of the issue, but my arm is starting up with a dull ache. Periodically my heart starts pounding and my chest starts to hurt. As the day rolls on, my symptoms worsen. Finally, after a call with my assistant where I practically yell and scream at them for getting me into this mess, my chest is throbbing. I try to get up to walk it off, but it's apparent that something is horribly wrong. I collapse to the floor and try to find my phone. I need to call 911! I hope that my desperate pleas to the dispatcher are understood. Darkness closes in and I feel my heart begin to stop. Suddenly I plunge back into consciousness surrounded by paramedics. What happened?
