Tachycardia-bradycardia syndrome: Electrophysiological mechanisms and future therapeutic approaches (Review) [PDF]

, 2017
Sick sinus syndrome (SSS) encompasses a group of disorders whereby the heart is unable to perform its pacemaker function, due to genetic and acquired causes.

Force‐sensing catheters during pediatric radiofrequency ablation: The FEDERATION Study [PDF]

, 2017
Background Based on data from studies of atrial fibrillation ablations, optimal parameters for the TactiCath (TC; St. Jude Medical, Inc) force‐sensing ablation catheter are a contact force of 20 g and a force‐time integral of 400

Synthetic Electrocardiogram Spectrogram Generation Using Generative Adversarial Network‐Based Models: A Comparative Study

Advanced Intelligent Systems, EarlyView.
Cardiovascular diseases are leading death causes; electrocardiogram (ECG) analysis is slow, motivating machine learning and deep learning. This study compares deep convolutional generative adversarial network, conditional GAN, and Wasserstein GAN with gradient penalty (WGAN‐GP) for synthetic ECG spectrograms; Fréchet Inception Distance (FID) and ...

Smooth Emergence from General Anesthesia after Deep Extubation in a Pediatric Patient Diagnosed with Catecholaminergic Polymorphic Ventricular Tachycardia: A Case Report

Medicina, 2023
Background: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare genetic disorder where catecholamine causes bidirectional ventricular tachycardia, potentially leading to cardiac arrest.

Blood pressure effects of SGLT2 inhibitors and GLP‐1 receptor agonists: Mechanisms, trial evidence and Real‐world data

British Journal of Clinical Pharmacology, EarlyView.
SGLT2 inhibitors and GLP‐1 receptor agonists modestly lower blood pressure across diverse patient populations, including those without diabetes. These effects appear largely independent of glycaemic control and offer additive value in high‐risk patients with overlapping comorbidities.

AV nodal reentrant tachycardia with a 2:1 right bundle branch block missed as bidirectional ventricular tachycardia in the first superficial evaluation

Romanian Journal of Internal Medicine, 2017
A 95-year old woman was admitted to our emergency unit because of acute abdominal pain. After urgent surgery according to the acute abdomen, she was referred to intensive care unit (ICU) of the emergency unit as she was intubated.

Antegrade and Retrograde Decremental Conduction Properties of an Accessory Pathway Associated with the Coronary Sinus Musculature

Indian Pacing and Electrophysiology Journal, 2015
A 32-year-old man underwent catheter ablation of an orthodromic atrioventricular reentrant tachycardia. The sinus rhythm electrocardiogram exhibited a normal PQ interval and no delta waves, but atrial pacing produced a prolonged PQ interval and wide QRS ...

Role of Catheter Ablation in Arrhythmogenic Right Ventricular Dysplasia [PDF]

, 2005
Arrhythmogenic right ventricular dysplasia/cardiomyopathy is a disorder characterized by frequent ventricular tachycardia originating from the right ventricle and fibro-fatty replacement of right ventricular myocardium. Though the disorder was originally

Glial cells in the heart: Implications for their roles in health and disease

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of cardiac autonomic ganglia within epicardial fat pads (posterior heart surface shown), containing vagal postganglionic neuron cell bodies, associated fibres, and glia. These ganglia receive cholinergic input from vagal preganglionic neurons and adrenergic input from sympathetic postganglionic neurons ...
