Abstract
We introduced a case of a 69-year-old female patient with mitral valve prolapse with severe regurgitation who was transferred from the ICU to a regular ward after undergoing mitral valve replacement surgery. Routine ECG examination showed that the precordial leads were affected by the apical pulsation, leading to pseudo-ST segment depression and prolonged QT interval. In clinical practice, ECG artifacts caused by apical pulsation, if not carefully distinguished, may lead to unnecessary examinations and treatments for patients. Our case emphasizes the importance of accurately identifying ECG artifacts.
期刊介绍:
The ANNALS OF NONINVASIVE ELECTROCARDIOLOGY (A.N.E) is an online only journal that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients.
ANE is the first journal in an evolving subspecialty that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. The publication includes topics related to 12-lead, exercise and high-resolution electrocardiography, arrhythmias, ischemia, repolarization phenomena, heart rate variability, circadian rhythms, bioengineering technology, signal-averaged ECGs, T-wave alternans and automatic external defibrillation.
ANE publishes peer-reviewed articles of interest to clinicians and researchers in the field of noninvasive electrocardiology. Original research, clinical studies, state-of-the-art reviews, case reports, technical notes, and letters to the editors will be published to meet future demands in this field.
