T-wave alternans (TWA) refers to an alternating pattern in the T-wave of the electrocardiogram (ECG) and is recognized as a marker of electrical instability. Visible or macroscopic alternans was first reported in the context of proarrhythmic conditions including Prinzmetal’s angina and long QT syndrome, and was often found to immediately precede the onset of ventricular tachycardia or fibrillation. More recently, techniques have been developed to measure microvolt-level T-wave alternans (MTWA) not visible to the human eye. The presence of MTWA has been linked with increased risk of sudden cardiac arrest (SCA) in several patient populations. This study presents the case of a patient who experienced VF during the recovery phase of an MTWA stress test. While there was no visible abnormality on the ECG which would alert to the impending arrhythmia, significant microvolt-level alternans was detected immediately prior to the cardiac arrest.

With a growing problem of overcrowded emergency departments, coronary computed tomography angiography (CCTA) may be a solution to address the management of chest pain patients. CCTA is increasingly recognized as an accurate, noninvasive tool to safely assess coronary artery disease. Advocates for the modality say it leads to earlier identification and management of obstructive coronary artery disease (CAD), rapid early discharge, improved flow of overcrowded emergency departments and reduced costs.

Indiana University (IU) Health La Porte Hospital in La Porte, Ind., made the decision to build an advanced EP procedure lab right in the community with holding areas, ancillary workspaces, office space and a clinical area. The vision was for the lab to encompass all aspects of arrhythmia care, beginning at the procedure area and finishing with the outpatient clinic. It also was extremely important that the space was efficient, cost-effective and flexible.
