Transient left ventricular apical ballooning in a patient with cardiac arrest after subarachnoid hemorrhage.

Subarachnoid hemorrhage (SAH) often accompanies cardiac abnormalities. Sudden cardiac arrest is also known to occur after SAH. A 32-year-old woman was admitted to our hospital because of cardiac arrest immediately after the onset of SAH. Return of spontaneous circulation was obtained by conventional advanced cardiovascular life support. After resuscitation, her echocardiogram showed left ventricular apical ballooning, which improved within 7 days. This is the first report presenting both sudden cardiac arrest and transient left ventricular apical ballooning after SAH.
