GLORIA ESCOBAR, José Miguel; ZULUAGA GARCIA, Juan Pablo; DUQUE GONZALEZ, Laura  and  RESTREPO BRAVO, Carlos Aníbal. Electrocardiographic abnormalities in subarachnoid hemorrhage. Cardiovasc. metab. sci [online]. 2019, vol.30, n.4, pp.136-142.  Epub Aug 12, 2024. ISSN 2954-3835.

Electrocardiogram abnormalities are particularly common among patients with subarachnoid hemorrhage (SAH). Phenomena such as ventricular tachycardia and fibrillation, torsade de pointes (mainly when a QTc is prolonged), sinus bradycardia, sinus tachycardia, atrial fibrillation, wandering atrial pacemaker, premature atrial, junctional, and ventricular complexes, atrioventricular block, neurogenic T waves, peaked P waves, shortened PR interval, inverted U waves and ST segment deviations have been described. Not only can these abnormalities mimic myocardial infarction or myocardial ischemia, but they also share an important prevalence with wall motion abnormalities like the Takotsubo cardiomyopathy. There have been few studies involving Holter monitoring in these patients, which constitutes an investigation subject with aims to standardize these complications in order to avoid adversely affecting discharge disposition and prolong in-hospital staying.

Keywords : Electrocardiogram; subarachnoid hemorrhage; giant T wave; arrythmias; ventricular fibrillation; ventricular tachycardia.
