OBJECTIVE The objective of this study us to stratify by gender a new cardiac electrical biomarker (CEB) diagnostic accuracy for detection of acute myocardial ischemic injury (AMII). METHODS This is a noninferiority retrospective, case-control, blinded study of 310 archived measured electrocardiograms (ECGs) acquired from 218 men and 92 women. The CEB is constructed from the derived ECG (dECG)...

• Although indirect fetal electrocardiograph}' in human pregnancies is becoming common,' electrocardiograms of mammalian fetuses in utero by the direct approach are not. During a general electrophysiological study of rabbit fetuses, we found that electrocardiograms could be obtained easily with needle electrodes. We expanded our observations by making recordings of cardiac potentials via needle...
BACKGROUND Therapy-refractory supraventricular tachycardia commonly results in hydrops and death in human fetuses. The purpose of this study in fetal sheep was to assess the feasibility of a minimally invasive fetoscopic approach for fetal transesophageal electrocardiography and stimulation aimed at diagnosis and termination of these tachycardias. METHODS AND RESULTS We studied a total of 10 ...
• Describe technical effects that can occur on ECG waveforms An important factor to consider when using findings on electrocardiograms for clinical decision making is that the waveforms are influenced by normal physiological and technical factors as well as by pathophysiological factors. Traditionally, the focus of bedside monitoring is detection of arrhythmia. However, continuous ST-segment mo...
