Assessing the Generalizability of a Deep Learning-based Automated Atrial Fibrillation Algorithm.

Automated detection of atrial fibrillation (AF) from electrocardiogram (ECG) traces remains a challenging task and is crucial for telemonitoring of patients after stroke. This study aimed to quantify the generalizability of a deep learning (DL)-based automated ECG classification algorithm. We first developed a novel hybrid DL (HDL) model using the PhysioNet/CinC Challenge 2017 (CinC2017) dataset (publicly available) that can classify the ECG recordings as one of four classes: normal sinus rhythm (NSR), AF, other rhythms (OR), and too noisy (TN) recordings.

Diuretics in the management of chronic heart failure: when and how.

Heart failure is an increasingly prevalent condition resulting in recurrent hospitalisations and significant mortality and morbidity. The management of heart failure has evolved, and multiple drugs have an established mortality benefit in heart failure with reduced ejection fraction. Although the focus should be on ensuring that patients are treated with the maximum tolerated doses of these guideline-directed therapies, diuretics continue to play a key role in the management of clinical congestion in all forms of heart failure.

A Smartphone-Based Model of Care to Support Patients With Cardiac Disease Transitioning From Hospital to the Community (TeleClinical Care): Pilot Randomized Controlled Trial.

Background: Patients hospitalized with acute coronary syndrome (ACS) or heart failure (HF) are frequently readmitted. This is the first randomized controlled trial of a mobile health intervention that combines telemonitoring and education for inpatients with ACS or HF to prevent readmission.

Objective: This study aims to investigate the feasibility, efficacy, and cost-effectiveness of a smartphone app-based model of care (TeleClinical Care [TCC]) in patients discharged after ACS or HF admission.

Nondominant Right Coronary Artery Occlusion: Small Vessel, Dramatic Sequelae.

Nondominant right coronary artery (NDRCA) occlusion is rare and generally affects a small volume of myocardium. Despite this, NDRCA occlusion can result in dramatic clinical sequelae. These cases demonstrate the characteristic electrocardiographic findings and consequences of NDRCA occlusion, highlighting the importance of recognition of this pathologic condition to institute appropriate management.
