Emergency cardiac problems are a frequent and significant occurrence in the daily life of the emergency physician. The first part of this article discusses some of the pearls and pitfalls of caring for the cardiac patient ranging from treating wide-complex tachycardia and troubleshooting pacemaker malfunction to diagnosing acute myocardial infarction in the setting of bundle branch blocks. The second part of this article updates the reader on several of the newer technologies and treatments, such as transesophageal echocardiography and intravenous amiodarone, now in use in the emergency department setting.

Right ventricular subclinical dysfunction in high-burden idiopathic outflow tract premature ventricular contraction population.

Divison of Arrhythmia, Cardiology and Vascular Department, St. David's Medical Center, Austin, TX, USA.
Background: The relationship between premature ventricular contractions (PVC) and right ventricular (RV) function is not widely known. Left ventricular (LV) dysfunction due to PVC is known as PVC-induced cardiomyopathy (PIC) and suppressing the PVC substrate would improve LV function. The effect of PVC ablation on changes in RV function in patients with subtle RV subclinical dysfunction remains unknown.

Purpose: Glucagon-like peptide 1 (GLP-1) receptor agonists (RAs) and basal insulin are currently used in the treatment of type 2 diabetes mellitus (T2DM) as long-acting injectables. In this study, we aimed to compare the cardiovascular (CV) and renal outcomes of GLP-1 RAs and basal insulin treatment in patients with T2DM.
Method: We conducted a propensity score-matched cohort study of patients from Chang Gung Memorial Hospital institutions between 2013 and 2021.

Introduction: Nemaline myopathy (NM), also known as Nemalinosis, is a rare congenital muscle disease with an incidence of 1 in 50000. It is characterized by nemaline rods in muscle fibers, leading to muscle weakness. We reported a case of NM revealed by cardiac involvement, and we highlighted the challenges in diagnosing this condition as well as its poor prognosis.

Unlabelled: Introduction Acute heart failure (AHF) is a life-threatening condition that requires swift diagnosis and tailored management to enhance patient outcomes. In the pursuit of more precise prognostic indicators, Tricuspid Annular Plane Systolic Excursion (TAPSE) and Pulmonary Arterial Systolic Pressure (PASP) have emerged as potential significant advancements. The TAPSE/PASP ratio, a novel parameter, has recently gained attention as a promising predictor of outcomes in acute heart failure.

Structural, architectural, contractile or electrophysiological alterations may occur in the left atrium (LA). The concept of LA cardiopathy is supported by accumulating scientific evidence demonstrating that LA remodeling has become a cornerstone diagnostic and prognostic marker. The structure and the function of LA and left atrial appendage (LAA) which is an integral part of the LA, are key elements for a better understanding of multiple clinical conditions, most notably atrial fibrillation (AF), cardioembolism, heart failure and mitral valve diseases.
