Concomitant Systolic and Diastolic Doppler Alternans: An Ominous Sign of Left Ventricular Dysfunction.
Cureus
October 2024
Cardiology, Beaumont Hospital, Royal Oak, USA.
Article Synopsis
- * A case study involved a 59-year-old male with non-ischemic cardiomyopathy, admitted for acute congestive heart failure, where severe left ventricular dysfunction was confirmed through echocardiogram findings, including blood flow variations known as Doppler alternans.
- * The echocardiographic detection of these variations occurred before any clinical symptoms, highlighting the importance of echocardiography for assessing heart function and guiding timely medical intervention.
Compact Arterial Monitoring Device Use in Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA): A Simple Validation Study in Swine.
Cureus
October 2024
Department of Anesthesiology, Uniformed Services University of the Health Sciences, Bethesda, USA.
Article Synopsis
- - Hemorrhage is the main cause of preventable death in trauma situations, leading to military and civilian advancements in medical practices, particularly through the use of tourniquets to manage extremity bleeding and save lives.
- - While tourniquets have significantly decreased deaths from bleeding in military settings, noncompressible hemorrhage still poses a major risk, especially before patients receive definitive medical care.
- - The study explores using a small, disposable pressure monitor during resuscitative endovascular balloon occlusion of the aorta (REBOA) to enhance blood pressure monitoring, facilitate better resuscitation practices, and reduce the need for blood products in extreme environments.
Stochastic and alternating pacing paradigms to assess the stability of cardiac conduction.

Department of Physiology, University of Bern, Bühlplatz 5, CH-3012 Bern, Switzerland. Electronic address:
Reentry, the most common cause of severe arrhythmias, is initiated by slow conduction and conduction block. Hence, evaluating conduction velocity and conduction block is of primary importance. However, the assessment of cardiac conduction safety in experimental and clinical settings remains elusive.

J Feline Med Surg
October 2024
National Taiwan University Veterinary Hospital, National Taiwan University, Taipei, Taiwan.
Article Synopsis
- The study aimed to find a stress-free method for evaluating heart rate variability (HRV) in cats using a stethoscope instead of traditional ECG recordings, which can cause stress during the process.
- Researchers recorded heart sounds from 29 cats in relaxed and stimulated states, calculating a new measure called the vasovagal tonus index (VVTI) to assess autonomic function.
- Results showed that the stethoscopic VVTI significantly decreased after stimulation, indicating reduced vasovagal tone, with findings being comparable between at-home and hospital settings, thus validating this cat-friendly approach.
Spatially discordant alternans due to periodic pacing site alternation.
Heart Rhythm
July 2024
Department of Pharmacology, University of California, Davis, California. Electronic address:
Background: Bidirectional ventricular tachycardia (BVT) is a rare type of ventricular tachycardia that is characterized by a beat-to-beat alternation in the QRS axis. Previous studies have shown that it is caused by alternating focal activities from 2 locations.
Objective: This study proposes a novel mechanism for the formation of spatially discordant alternans (SDA) due to the periodic pacing site alternation that occurs in BVT.
