Abstract

A 62-year-old female patient suffering from ST elevation myocardial infarction (STEMI) was transported to a cardiology facility. During transport, the monitor triggered an alarm for tachycardia despite a normal pulse. The reason was a misinterpretation of the ECG software, which double counted the QRS complex. QRS double counting has been reported in the setting of hyperkalemia only. In this case report, QRS double counting in association with STEMI is documented for the first time. Healthcare workers who are monitoring patients with myocardial infarction should be aware of this misdiagnosis and able to recognize the pattern.
