Brain Waves

Report:

Sinus rhythm 90/min

Prominent T waves

Prolonged QT interval

Comment:

The patient became brain dead soon after this trace was taken, from a massive subarachnoid hæmorrhage. The “cerebral” repolarisation changes are most specific with giant T wave inversion, but prominent upright T waves, also with prolonged QT intervals, are as common.

In hyperacute MI pattern, the ST segment and the upstroke of the T wave tend to be more convex than here and there are usually marked reciprocal changes in a set of leads. All the same, CVA patterns may be indistinguishable from those of acute infarction118.
