RESUMEN

Los enfermos con hemorragia subaracnoidea (HSA) presentan con frecuencia alteraciones electrocardiográficas (ECG), las más frecuentes son alargamiento del segmento QT, ondas T negativas, elevación o inversión del segmento ST y ondas U. La inversión de las ondas T asociada a la prolongación del QT se correlaciona con alteraciones de la contractilidad ventricular y es una indicación para practicar ecocardiograma. Se reporta el caso de un paciente con HSA secundaria a ruptura de aneurisma intracraneal que presentó cambios electrocardiográficos, enfatizando en la patogénesis de éstos y el impacto que tienen en el comportamiento clínico y la evolución.
