Advanced Speckle-Tracking Echocardiography Could Play a Crucial Role in the Diagnosis of Post-Implanted Cardiomyopathy Associated with a Leadless Pacemaker System.

A leadless pacemaker (LP) is a modern alternative to a transvenous pacemaker, allowing certain complications to be avoided; however, some cannot be eliminated. To highlight the essential role of advanced speckle-tracking echocardiography (STE) in diagnosing pacing-induced cardiomyopathy (PICM) caused by an LP. A 79-year-old male, after LP implantation a year earlier, was admitted due to heart failure (HF).

Smartphone App-Based Remote Monitoring Challenges in Patients with Cardiac Resynchronization Therapy Defibrillators-A Multicenter Study.

: Remote monitoring (RM) cardiac implantable electronic devices for adults delivers improved patient outcomes. However, previously used bedside transmitters are not optimal due to deficient patient adherence. The goal of this study was to evaluate the efficacy of RM regarding the connectivity of smartphone app-based solutions, adherence to scheduled automatic follow-ups, and prevalence of alert-based events.

A Frustrated Antipolar Phase Analogous to Classical Spin Liquids.

The study of magnetic frustration in classical spin systems is motivated by the prediction and discovery of classical spin liquid states. These uncommon magnetic phases are characterized by a massive degeneracy of their ground state implying a finite magnetic entropy at zero temperature. While the classical spin liquid state is originally predicted in the Ising triangular lattice antiferromagnet in 1950, this state has never been experimentally observed in any triangular magnets.
