Abstract

This case report describes a patient in their 40s who presented to the emergency department with acute chest pain.

Electrocardiogram Recording in the Prone Position—Reply

“…However, the commonly used method of prone ECG acquisition also leads to a decrease in the amplitude of ECG waveforms. According to the findings of our case report 1 and those of Chieng et al, 4 the amplitudes in the precordial leads of prone ECG are approximately 70% to 75% of the supine counterparts, which may be better than the new method.…”

“…In Reply We would like to express our gratitude to Cobos Gil et al for their thought-provoking and insightful comments on our case report, 1 which discussed how anterior leads ST-segment elevation might be missed on the findings of an electrocardiogram (ECG) recorded in the commonly used prone position. Their comments addressed a new prone ECG acquisition method based on the concept of the mirror image electrocardiogram reported by Kors and van Herpen.…”
