Asystolie et douleur du membre supérieur gauche : une cause inattendue

We describe the case study of a 44-years-old patient who have been admitted in emergencies for a left upper limb pain and throughout presented an asystole which necessitated an external cardiac/heart massage. We did not find any cardiovascular pathology in the etiological checkup. The diagnosis is a vasodepressor syncope due to an acute hyperalgetic shoulder on a calcification of supraspinatus left tendon. These kind of syncopes are more often benign, however some of them can be serious and many atypical forms of difficult diagnosis appear a posteriori. This kind of syncope with a pain signal is rarely started with pain of upper limb.
