Symptom-complex characterized by palpitation, dyspnea, precordial pain, fatigue, exaggerated emotional responses with increased cardiac awareness, and occasionally, systolic hypertension
1864 – First recorded by the British in the Crimea, when termed ‘palpitation’, and later the constellation of symptoms was referred to by Hartshorne as “cardiac muscular exhaustion“
1864 – Maclean WC (Professor of military medicine at the Army Medical School, Netley) initially felt army discharges secondary to ‘diseases of the circulatory system’ (8% of the those discharged between 1863-1866 of the 5500 case reviewed) were thought to be the effect of exertion on a soldier’s chest constricted by tight webbing and equipment/li>
‘The pack-straps press on important muscles, arteries, veins and nerves to a degree which only those who have carried the loaded pack can appreciate… You can well imagine how impossible it must be to make severe exertion under so many disadvantages without suffering‘Maclean 1864
1870 – A.B.R. Myers reviewed extensively, in his ‘Alexander’ Prize Essay the writings of Maclean, E.J. Parkes and Aitken on the matter of the ‘irritable heart’ of combat soldiers. He concluded that three major factors accounted for this difference: rheumatic fever, Bright’s disease and violent manual labour. He also pointed to the soldier’s equipment
‘His waist-belt adds to the constriction below the chest, and his tunic collar above it… and then, to complete the artificial chest case, the knapsack straps supply all that is requisite, whilst the pouch-belt adds its share to the general compression. The chest, thus fixed as it were in a vice, has little or no power of expansion, and the circulation through the heart, lungs and great vessels is proportionately impeded‘Myers 1870
1871 – Da Costa defined as “irritable heart syndrome,” in cases from the American Civil War. He found the disorder, was not confined to the infantry but affected the cavalry and artillery so the packs were unlikely to be to blame. Although this was widely regarded as a disorder suffered by soldiers in wartime, Da Costa made the important observation that the same cluster of symptoms could also be seen in civilians.
The ‘syndrome’ has undergone many name changes with the evolution of more advancements in physiological and anatomical testing. From ‘cardiac neurosis,’ ‘disordered action of the heart,’ ‘soldier’s heart,’ and ‘neurocirculatory asthenia’; to ‘vasoregulatory asthenia,’ (Holmgren) ‘hyperkinetic heart syndrome,’ (Gorlin) or ‘hyperdynamic β-adrenergic circulatory state.(Frohlich).
