How is it that a pneumothorax can cause heart to stop?

Tension: A tension pneumo causes pressure build up with air and squeezes your heart until it can't beat anymore.

Blood flow: In general, your heart beats until it fails to get adequate oxygen/blood flow. The pressure from a "tension pneumothorax" compresses/prevents blood from entering the right side of the heart. Decreased blood return to the heart results in decreased output (i.e. How much blood it has to pump out). The heart gets its oxygen/circulation from the left side output.
