In brief: EtOH is a depressant

The brain monitors&adjusts heart muscle rate & strength of contraction 20-30 times/second.
After alcohol, many people express feeling they keep hidden/controlled while sober. Brain control (thus also heart function) is highly influenced by feelings to include our history/memory/complex-associations. For some, alcohol greatly increases cardiac arrhythmia; Docs can't see causes; only end behaviors.
