Patients with cerebrovascular accidents exhibited a unique electrocardiographic pattern featuring large amplitude T waves and fused U waves, likely indicating a prolonged Q-U interval.
17 patients with cerebrovascular accidents (7 with cerebral hemorrhage, 7 with subarachnoid hemorrhage, 3 with unclassified C.V.A.) evaluated primarily at Charity Hospital in New Orleans. Ages ranged from 32 to 79 years.
Electrocardiographic changes, specifically Q-T interval duration, T wave amplitude and configuration, and U wave presence.surrogate
This early case series identifies a distinct electrocardiographic pattern of prolonged Q-T intervals and large T and U waves associated with acute cerebrovascular accidents.
Absolute Event Rate: 0% vs 0%
An electrocardiographic pattern was encountered in patients with cerebrovascular accidents which consisted primarily of T waves of large amplitude and duration. Large U waves were often present which may fuse in part or entirely within the T wave. Because of the presence and fusion of the T and U waves, the prolonged Q-T interval associated with the pattern was most probably a Q-U interval.
