ECG Changes in Intracranial Hemorrhage

All About Cardiovascular System and Disorders

Mechanism is thought to be due to sustained sympathetic stimulation, probably caused by dysfunction of insular cortex resulting in reversible neurogenic damage to the myocardium which could include contraction bands and subendocardial ischemia [2]. Lead electrocardiogram changes after supratentorial intracerebral hemorrhage.

Annals of Emergency Medicine 2012; 60(12):766-776. EKG shown here: LAFB with no clear signs of OMI or ischemia. Diagnosis of Acute Myocardial Infarction in the Presence of Left Bundle Branch Block using the ST Elevation to S-Wave Ratio in a Modified Sgarbossa Rule. No labs were performed. EKG and CT head were performed.

Right precordial ST depression in a patient with chest pain

Dr. Smith's ECG Blog

Computer read: "Non-specific ST abnormality, consider anterior subendocardial ischemia" There are very poor R-waves in V1-V4 suggesting old anterior MI. Firstly, subendocardial ischemia does not localize on 12-Lead ECG. But the real question at hand is: Are these precordial ST-depressions a result of subendocardial ischemia?
