Technician:STAFF ER Test ind:WILSON II II Referred by: SHARON WILSON DIAGNOSIS: • A 33-year-old man presented to the emergency department with the chief complaint of headache and dizziness. • Headache started two days prior. It is described as throbbing I aVR V5 in nature, located bitemporally, came on gradually over an 10mm/mV 150Hz 7.1.1 12SL 239 CID: 74 hour and 25mm/s has been intermittent since, rated 4 out of 10 on pain scale (10 being worse) when it occurs. Achieves II aVL minimal relief with NSAIDs. • Dizziness started at approximately the same time as the headache, but was worse the morning of presentation prompting patient to come to the emergency department. III aVF • He endorsed photophobia, anorexia, nausea, and four episodes of non-bloody, non-bilious emesis. • He denied chest pain, dyspnea on exertion, orthopnea, V1 paroxysmal dyspnea, abdominal pain, or diarrhea. Medications • None QTc of 480 msec. Inverted T waves highlighted.

Past Medical History • Hypertension and Type 2 Diabetes Mellitus V5 Family History 25mm/s 10mm/mV 150Hz 7.1.1 12SL 239 CID: 139 • Hypertension – Mother and Father Social History • Smoke 0.5 packs per day for five years, quit two years prior Physical Exam Blood pressure: 255/170 mmHg; Heart Rate: 109/min General: Patient was alert in mild distress from headache. Fundoscopic exam: No papilledema Cardiac exam: Tachycardic, apical impulse was non-displaced and there was no murmur, gallop, or rub Neurologic exam: Normal strength, sensation, coordination, and proprioception throughout; reflexes were brisk and symmetric bilaterally and cranial nerves were intact • T wave alterations are a non-specific finding with a broad differential which includes: • acute coronary syndrome • central nervous system event • pulmonary embolus • Wellens’ syndrome • left ventricular hypertrophy with strain • digitalis effect • bundle branch block • pre-excitation • persistent juvenile pattern.1,2 • ECG changes during CNS events have been described with: • subarachnoid hemorrhage (SAH) • cerebrovascular accident • intracerebral hemorrhage • Trauma • CNS mass.1-3 • ECG findings classically described with CNS events include: • QTc prolongation (≥460 msec) • T wave inversion EID:53 EDT: 10:42 21-AUG-2011 ORDER: 72635768 ACCOUNT: 020020589634 • prominent U wave (≥100 µV amplitude) Page 1 of 1 • ST segment elevation • ST segment depression.3,4 • In a study of 100 patients with SAH, these changes were noted in 16%, 7%, 15%, 9%, and 3% of patients, respectively, with at least one of these findings seen in a total of 41% of patients. Non-contrast head CT showing a hemorrhage in the left thalamus with extension into the the third ventricle. Additional Studies: II Discussion Troponin (ref, <0.04 ng/ml): 0.23 (at 0 hr), 0.23 (at 1 hr), 0.21 (at 3 hr) Echocardiogram: mild concentric left ventricular hypertrophy (LV), normal LV and right ventricular systolic function, impaired LV diastolic function, and mild regurgitation of the aortic, mitral, and tricuspid valves EID:3 EDT: 11:40 22-AUG-2011 ORDER: 72632910 ACCOUNT: 020020589634 Page 1 of 1 Hospital Course • Cardiology was consulted for consideration of acute coronary syndrome and initiation of aspirin, clopidogrel and intravenous heparin therapy. • While being evaluated by Cardiology, the head CT was completed showing intracranial hemorrhage. • The patient was diagnosed with hypertensive emergency with a spontaneous intracranial hemorrhage. • The patient was admitted to the ICU and placed on a nicardipine infusion for blood pressure control. • No acute management was required for the intracranial hemorrhage and repeat imaging on hospital day 4 showed a decrease in extent of the hemorrhage. • Evaluation for secondary causes of hypertension was negative for renal artery stenosis, hyperaldosteronism, and pheochromocytoma. • An ECG on hospital day 7 showed resolution of T wave inversion in V3 and decreased depth of the T wave inversions in V4-V6. • The patient was transitioned to oral anti-hypertensive therapy, requiring a total of five medications, and discharged on hospital day 11. • Other noted ECG abnormalities reported include: • sinus bradycardia • premature ventricular contractions • atrial fibrillation • first-degree heart block.5 • In a study of 110 patients with intracranial hemorrhage, excluding stroke and SAH, ECG abnormalities were noted in 64% of patients with rhythm disturbances listed above being the most common abnormality (69%). • Similar rhythm disturbances have also been reported with SAH.3 References 1.
