Reversible third-degree atrioventricular block in a Poodle-Toy with degenerative mitral valve disease and pyometra

Brazilian Journal of Veterinary Medicine, 2021
Third degree atrioventricular block is a severe arrhythmia, being the most common   indication for artificial cardiac pacing in dogs. Spontaneous reversion to normal sinus rhythm is very rare or exceptional.

A Real-Time PPG Peak Detection Method for Accurate Determination of Heart Rate during Sinus Rhythm and Cardiac Arrhythmia

Biosensors, 2022
Objective: We have developed a peak detection algorithm for accurate determination of heart rate, using photoplethysmographic (PPG) signals from a smartwatch, even in the presence of various cardiac rhythms, including normal sinus rhythm (NSR), premature

A new deep learning algorithm of 12-lead electrocardiogram for identifying atrial fibrillation during sinus rhythm

Scientific Reports, 2021
Atrial fibrillation (AF) is the most prevalent arrhythmia and is associated with increased morbidity and mortality. Its early detection is challenging because of the low detection yield of conventional methods.

Continuous positive airway pressure therapy converted atrial fibrillation in a patient with obstructive sleep apnea

Journal of Arrhythmia, 2014
Background: Obstructive sleep apnea (OSA) is one of the possible causes of atrial fibrillation (AF). Continuous positive airway pressure (CPAP) therapy may lower the recurrence rate of AF after cardioversion to normal sinus rhythm. We report a case of AF

Temporary cardiac arrest in patient under robotically assisted total thyroidectomy causing carotid sinus hypersensitivity -A case report- [PDF]

Korean Journal of Anesthesiology, 2010
Carotid sinus hypersensitivity (CSH) is an exaggerated response to carotid sinus baroreceptor stimulation. Bradycardia, hypotension, and syncope are common manifestations of CSH.

Analyzing artificial intelligence systems for the prediction of atrial fibrillation from sinus-rhythm ECGs including demographics and feature visualization

Scientific Reports, 2021
Atrial fibrillation (AF) is an abnormal heart rhythm, asymptomatic in many cases, that causes several health problems and mortality in population. This retrospective study evaluates the ability of different AI-based models to predict future episodes of ...

Wide and narrow QRS tachycardias: What is the mechanism?

Indian Heart Journal, 2020
A 50-year-old lady was referred for radiofrequency catheter ablation of narrow QRS tachycardia that was terminated with intravenous adenosine. Twelve-lead Electrocardiogram (ECG) was normal during sinus rhythm.

Sinus or not: a new beat detection algorithm based on a pulse morphology quality index to extract normal sinus rhythm beats from wrist-worn photoplethysmography recordings

Physiological Measurement, 2018
Objective: Wrist-worn photoplethysmography (PPG) can enable free-living physiological monitoring of people during diverse activities, ranging from sleep to physical exercise. In many applications, it is important to remove the pulses not related to sinus
