why does my heart race after drinking alcohol?

EtOH is a depressant: Our brain monitors&adjusts heart muscle rate&strength of contraction 20-30 times/second. After alcohol, many people express feelings kept hidden/controlled while sober. Brain control (thus also heart function) is highly influenced by feelings, including internalized history/memory/complex-associations. For some, Etoh greatly increases cardiac arrhythmias. Docs can't see causes; only end behaviors.
