Electrocardiographic findings in acute cerebrovascular hemorrhage a prospective study of 70 patients

Abstract

In 1938, Asehenbrenner and Bodeehteis stated that intracranial lesions may be responsible for electrocardiographic abnormalities, but the first report of ECG changes in patients with cerebrovascular accidents was given by Byer, Ashman and Toth, in 1947 6. in 1954, Burch, Meyers and AbildskovS described a pattern of QT prolongation, abnormal T waves, and U waves which they considered distinctive of acute stroke. Since then, several reports about the prevalence and pathophysiology of ECG findings in different cerebrovascular events has accumulated 4,5,

Prevalence and Characterization of ECG Abnormalities After Intracerebral Hemorrhage

“…It is remarkable that only one study reported QTc prolongation as the most frequently observed ECG abnormality, while others described it as an infrequently observed ECG abnormality [1,3,17,18]. One study observed that ectopic beats >10% were the most frequently observed ECG abnormality, in contrast to our and other studies [1,3,18].…”

“…Other studies also found that sinus brady-/tachycardia and ST-T morphologic changes were frequently observed ECG abnormalities in the acute phase of intracerebral hemorrhage [1,3,17,18]. It is remarkable that only one study reported QTc prolongation as the most frequently observed ECG abnormality, while others described it as an infrequently observed ECG abnormality [1,3,17,18].…”

ECG Changes in Subarachnoid Haemorrhage: A Synopsis

“…Other changes seen commonly include presence of a U wave, a Q wave, prolonged QTc intervals and large, flattened or notched T waves [15].…”

Severe Intracranial Bleeding Mimicking Acute Inferior Myocardial Infarction with Right Ventricular Involvement

“…ECG abnormalities have been described in the context of cerebrovascular accidents, most commonly consisting of QTc interval prolongation and ST-T segment abnormalities [1, 2]. Moreover, it is also known that subarachnoid hemorrhage can be associated with acute LV dysfunction [3].…”

“…Electrocardiographic (ECG) abnormalities and acute left ventricular (LV) dysfunction have been described in the context of cerebrovascular accidents [1, 2, 3]. Although there are rare case reports of patients with ECG changes consistent with an acute myocardial infarction, ECG patterns indicative of a localized myocardial infarction in the context of an intracranial hemorrhage are uncommon.…”
