Abstract

OBJECTIVE: To determine the major electrocardiographic changes in patients with cerebral vascular disease in the acute phase of the disease. MATERIAL AND METHODS: A descriptive records of patients with cerebrovascular disease (CVD), ischemic or hemorrhagic, users of the emergency department of a Regional General Hospital IMSS Querétaro, in the period from July to December 2010. A chart review of patient referred with diagnosis and included records of patients 18 years or more, with complete medical history, 12 lead electrocardiogram and cranial computed tomography simple and/or contrast to determinate the type of cerebral vascular disease. Were analyzed using means, ranges, frequencies and percentages. RESULTS: Of 79 patients, predominantly male 53.2%, with an age range of 65 years and over (70.9%) The average age was 69.72 years. The predominant ischemic stroke 78.5%, 21.5% followed by bleeding.. Evaluated the electrocardiograms of 54.4% were abnormal. Electrocardiographic changes presented were: T wave acuminate (15.2%) with a frequency of 50% for each type of stroke, bundle branch block (12.7%) corresponding to 80% for ischemic stroke, negative T wave (8.9%) with predominance in the ischemic type and atrial fibrillation 85.7% (7.6%) only in the ischemic type. Of the aggregate comorbidities were hypertension (13.9%), followed by type 2 diabetes mellitus (10.1%). CONCLUSIONS: The ECG changes were found in more than 50% of patients with ischemic cerebrovascular disease or bleeding, predominantly of the acuminate and negative T waves, bundle branch block and atrial fibrillation in patients with ischemic stroke in the majority.
