ECG Changes in Intracranial Hemorrhage

All About Cardiovascular System and Disorders

Cerebrovascular damage can cause cardiac arrhythmias related to disinhibition of right insular cortex with resulting increased sympathetic tone. Lead electrocardiogram changes after supratentorial intracerebral hemorrhage. 2012 Dec;7(4):290-4. Lead electrocardiogram changes after supratentorial intracerebral hemorrhage.

A man in his 70s with weakness and syncope

Dr. Smith's ECG Blog

Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.

A young F is hyperthermic, delirious, and dry: Fever-induced Brugada? Diphenhydramine toxicity? Tricyclic?

Dr. Smith's ECG Blog

J Electrocardiology 45 (2012):433-442. Fever not only unmasks a Brugada-type electrocardiogram (ECG) but also increases the risk of ventricular tachyarrhythmias such as ventricular fibrillation (VF) or sudden cardiac death. Conclusion of this paper: Fever is a great risk factor for arrhythmia events in Brugada Syndrome patients.
