title: [Severe hyperventilation as a differential diagnosis of acute coronary syndrome].
abstract: We report a case where a 30-year-old, otherwise healthy female was admitted to hospital with symptoms of hyperventilation, including chest discomfort and an abnormal ECG showing ST depressions and T-wave inversions. The ECG changes disappeared spontaneously during the next 24 hours as the patient was calmed down. A few weeks after discharge, the ECG changes were partially reproduced during a six-minute hyperventilation test. It is worth remembering that severe hyperventilation can cause ECG changes similar to those seen in acute coronary syndrome.
