Less common etiologies include uremia, bacterial or tubercular pericarditis, chronic idiopathic pericarditis, hemorrhage, and other causes such as autoimmune diseases, radiation, myxedema, etc. This may be in the strength of the pulse ( or the blood pressure recorded ) — or it may be in one or more waveforms in the ECG recording.

Blood pressure was normal (109/83). NOTE #3: In the context of a long QTc or ischemia — the finding of ST segment and/or T wave alternans may predict the occurrence of malignant ventricular arrhythmias. A 30-something was in the ED for some minor trauma when he was noted to have a fast heart rate. but only when asked.

BackgroundDelayed cerebral ischemia represents a significant contributor to death and disability following aneurysmal subarachnoid hemorrhage. In murine studies (n=30), the endovascular perforation model was predominantly used, while rat studies primarily employed intracisternal blood injection to mimic subarachnoid hemorrhage.

Background:Ischemia on diffusion weighted imaging (DWI) after intracerebral hemorrhage (ICH) increases the risk of future ischemic stroke. Though cortical superficial siderosis (cSS) is also a hemorrhagic small vessel disease subtype, it is unclear if cSS similarly relates to DWI lesions. and cSS in 10.6%.

Background:Ischemic lesions on diffusion weighted imaging (DWI) occur in one-third of intracerebral hemorrhage (ICH). Due to conflicting prior studies, it is uncertain if the degree of systolic blood pressure reduction increases the risk. and LVH was seen in 23.5%.

This ECG is diagnostic of diffuse subendocardial ischemia. Because the patient had asystole, was resuscitated without difficulty, and had no neurologic function, suspected a cerebral hemorrhage was suspected as the etiology of the arrest, specifically subarachnoid hemorrhage. What is the utility of a head CT in cardiac arrest?

Also consider non-hemorrhagic volume depletion, dehydration : orthostatic vitals may uncover this [see Mendu et al. (3)]. Evidence of acute ischemia (may be subtle) vii.
