Harlequin syndrome, also known as differential hypoxia (DH) or North-South syndrome, is a serious complication of femoro-femoral venoarterial extracorporeal membrane oxygenation (V-A ECMO). Moreover, Harlequin syndrome is caused by competing flows between the retrograde oxygenated ECMO output and the anterograde ejection of poorly oxygenated blood from the native heart. In the setting of impaired pulmonary gas exchange, the addition of an Impella device (ECPELLA configuration), although beneficial for ventricular unloading and hemodynamic support, may further exacerbate this competition and precipitate DH.

Introduction: Wave speed (WS) mapping, enabled by omnipolar technology, allows for real-time visualization of local conduction velocity (CV). Its utility in ventricular tachycardia (VT) ablation has not been fully characterized.
Methods And Results: We describe a case series of patients undergoing VT ablation in which WS mapping was applied alongside established techniques such as peak frequency (PF) mapping and isochronal late activation mapping (ILAM).

Cardiac arrhythmias are a major health concern around the world, causing morbidity and mortality in a wide range of people. The timely and accurate diagnosis of arrhythmias is critical for optimal clinical management and intervention. Deep learning techniques have developed as powerful tools for detecting arrhythmias in recent years, taking advantage of advances in signal processing and machine learning.

Background: Heart failure (HF) mortality is rising despite robust evidence-based guidelines. Hospitalization presents an opportune time to optimize care. Inpatient care pathways (CP) embedded in the electronic health record (EHR) can enhance adherence to guidelines by providing real-time decision support.
