Arrhythmias in the History: Lovesickness.

Lovesickness has been termed a real disorder, with a specific cause, pathogenesis, and cure: it has been attested to in the medical literature since classical times and may still have a place in current medicine in the frame of psychiatry and humoral disorders. Although in different cultures there is a general agreement on the symptoms, including fever, agitation, loss of appetite, headache, rapid breathing, and palpitations, the treatments vary greatly in the various cultural contexts.
