SUMMARY

Seventy patients with hemorrhagic stroke were prospectively evaluated regarding the electrocardiographic abnormalities observed within the first 48 hours of the ictus. Group I comprised 55 patients with spontaneous cerebral hemorrhage, and group II 15 patients with subarachnoid hemorrhage. Patients taking cardiac drugs (beta blockers, calcium-channel blockers, inotropic drugs) or with severe metabolic/electrolyte disturbances were excluded. The most common ECG abnormality was a prolonged Q-Tc interval: group I, 37 (67.2%); group II, 8 (53.3%). Only 4 (7.2% patients of group I and no patient of group II had a normal ECG. No relation was found between the site of the intracerebral hematoma and the occurrence of any particular ECG change. A prolonged Q-Tc may be related to the development of severe cardiac arrhythmias observed in some patients with acute cerebral hemorrhage.

Key words: cerebral hemorrhage, electrocardiogram, Q-Tc prolongation.


RESUMO

Foram analisados os achados eletrocardiográficos obtidos dentro das primeiras 48 horas de instalação de acidente vascular cerebral hemorrágico em 70 pacientes. O grupo I foi composto de 55 pacientes com hematoma intracerebral espontâneo e o grupo II, de 15 pacientes com hemorragia subaracnóidea. Pacientes em uso de drogas cardíacas (beta bloqueadores, bloqueadores de cálcio, drogas inotrópicas) e/ou distúrbios metabólico/eletrolíticos graves foram excluídos. A alteração eletrocardiográfica mais comum em ambos os grupos foi o prolongamento do intervalo Q-Tc: grupo I, 37 (67,2%); grupo II, 8 (53,3%). Os eletroctardiogramas foram normais em 4 (7,2%) pacientes do grupo I e em nenhum paciente do grupo II. Não houve correlação significativa entre o local do hematoma cerebral e a ocorrência de alguma alteração específica do eletrocardiograma. O prolongamento do intervalo Q-Tc pode representar fator de risco potencial para o desenvolvimento súbito de arritmias cardíacas graves, observado em alguns pacientes com acidentes vasculares cerebrais hemorrágicos.

Palavas-chave: hemorragia cerebral, eletrocardiograma, prolongamento do intervalo
