Other tests that may be helpful for diagnosis include the following:

  • ECG: Cardiac arrhythmias and myocardial ischemia may be evident. Aneurysmal SAH may be associated with several ECG changes, including peaked P waves, prolonged QT interval, and tall T waves.

  • Echocardiography: Cardiac sources of embolism, including endocarditis and myxomas, may be visualized in cases of infectious or neoplastic aneurysms.

  • Evoked potentials and EEG: These functional neurophysiologic studies may be used to monitor cerebral aneurysm surgery or patients critically ill with aneurysmal SAH.
