Relation of ECG changes to neurological outcome in patients with aneurysmal subarachnoid hemorrhage.

Background: Electrocardiographic (ECG) alterations occurring during the course of subarachnoid hemorrhage (SAH) have been described frequently, but the incidence, patterns, and prognostic significance are not well defined. This study was designed to investigate these features.

Methods: All patients admitted to a 31-bed department of intensive care between 1993 and 2000 with acute aneurysmal SAH documented by cerebral angiography or autopsy were included.

Cardiac manifestations after subarachnoid hemorrhage: a systematic review of the literature.

Cardiac alterations associated with subarachnoid hemorrhage (SAH) have been recognized and frequently reported. We systematically reviewed the literature on MEDLINE using the key words: SAH + (heart, cardiac, electrocardiogram, cardiac enzymes, troponin, myoglobin, echocardiography, scintigraphy, Holter, and regional wall motion abnormalities) and included all articles describing cardiac abnormalities in the course of SAH whether spontaneous or secondary. The diagnosis of SAH was established by computed tomography scan, lumbar puncture, or brain autopsy.
