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

• 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.

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
