Digoxin is frequently used for rate control of atrial fibrillation (AF). It has, however, been associated with increased mortality. remains unclear whether digoxin itself responsible the mortality (toxic drug effect) or it prescribed to sicker patients inherently higher due comorbidities. The goal our study was determine relationship between and in AF. association assessed enrolled AF Follow-Up Investigation Rhythm Management (AFFIRM) trial using multivariate Cox proportional hazards models....
Despite the growing use of point care ultrasound (POCUS) in contemporary medical practice and existence clinical guidelines addressing its specific applications, there remains a lack standardization agreement on optimal practices for several areas POCUS use. The Society Point Care Ultrasound (SPOCUS) formed working group 2022 to establish set recommended best POCUS, applicable clinicians regardless their training, specialty, resource setting, or scope practice. Using three-round modified...
Agitated saline bubble studies in conjunction with echocardiography, particular transesophageal are currently the principal means diagnosis of patent foramen ovale (PFO). We describe techniques and guidelines for detection exclusion a PFO. The potential misinterpretation these exists therefore, several false positive negative scenarios illustrated discussed.
Point-of-care ultrasound (POCUS) involves the acquisition, interpretation, and immediate clinical integration of ultrasonographic imaging performed by a treating clinician. The current state cardiac POCUS terminology is heterogeneous ambiguous, in part because it evolved through siloed specialty practices. In particular, medical literature colloquial conversation contain wide variety terms that equate to POCUS. While diverse aided development dissemination throughout multiple specialties,...
Background Medication treatment decisions in heart failure ( HF ) are currently informed by measurements of brachial artery pressure, but ventricular afterload is more accurately represented central aortic which differs from pressure. We sought to determine whether aggressive titration vasoactive medicines beyond goal‐directed medical therapy GDMT based upon pressure improves exercise capacity and cardiovascular structure‐function. Methods Results Subjects with chronic (n=50) underwent...
Background: Patients with high-risk coronary artery disease (CAD) may be difficult to identify. Methods: Using the PROMISE (Prospective Multicenter Imaging Study for Evaluation of Chest Pain) cohort randomized computed tomographic angiography (n=4589), 2 predictive models were developed CAD, defined as left main stenosis (≥50% stenosis) or either (1) ≥50% [50] (2) ≥70% [70] 3 vessels 2-vessel CAD involving proximal anterior descending artery. Pretest predictors examined using stepwise...
Cardioversion is a very commonly performed procedure for persistent atrial fibrillation (AF). However, there no well-defined protocol to address failed external electrical direct current cardioversion. The aim of the study test efficacy pre-defined stepwise cardioversion patients with AF ≤12 months. Success was achievement sinus rhythm.The population included months duration requiring rhythm management. Patients were offered using different electrode placement locations, applying compression...
Most out-of-hospital ventricular fibrillation (VF) is prolonged (>5 minutes), and defibrillation from VF typically results in asystole or pulseless electrical activity. Recent visual epicardial observations an open-chest, open-pericardium model of swine indicate that blood flows the high-pressure arterial system to lower-pressure venous during untreated VF, thereby overdistending right ventricle apparently decreasing left size. Therefore, inadequate stroke volume after has been postulated as...
Introduction: Changes due to biventricular pacing have been documented by shortening of QRS duration and echocardiography. Compared normal ventricular activation, the presence left bundle branch block (LBBB) results in a significant change cardiac cycle time intervals. Some these used quantify underlying dyssynchrony, assess effects pacing, guide programming devices. This study evaluates simple noninvasive method using accelerometers attached skin measure intervals biventricularly paced...

The association of QRS duration (QRSd) with morbidity and mortality is understudied in patients atrial fibrillation (AF). We sought to assess any prolonged increased risk death or hospitalization among AF. was retrieved from the baseline electrocardiograms enroled Atrial Fibrillation Follow-Up Investigation Rhythm Management (AFFIRM) study divided into three categories: <90, 90–119, ≥120 ms. Cox models were applied relating hazards hospitalizations QRSd. Among 3804 AF, 593 died 2305...
