Ivabradine (Procoralan) [PDF]

, 2008
peer reviewedIvabradine (Procoralan), a new If inhibitor which acts specifically and in a dose-dependent manner on the pacemaker activity of the sinoatrial node, is a pure heart rate lowering agent.

Catheter ablation of sinoatrial node reentrant tachycardia

Journal of the American College of Cardiology, 1994
This study evaluates 1) the safety and efficacy of catheter delivery of radiofrequency current to eliminate sustained sinoatrial node reentrant tachycardia; 2) the incidence of sinoatrial node reentrant tachycardia in the current group of patients undergoing electrophysiologic study for paroxysmal supraventricular tachycardia; and 3) the association of

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, Volume 309, Issue 2, Page 417-450, February 2026.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Rhythm Generating Mechanisms in Rat Sinoatrial Node

Current Medical Issues
Background: The major membrane currents responsible for sinoatrial (SA) rhythm generation are generally studied in isolated cardiac cells using electrophysiological tools. Such studies are resource and labor-intensive.

Rare Case of Rapidly Worsening REM Sleep Induced Bradycardia

Case Reports in Cardiology, 2015
Sinoatrial arrest also known as sinus pause occurs when sinoatrial node of the heart transiently ceases to generate the electrical impulse necessary for the myocardium to contract. It may last from 2.0 seconds to several minutes. Etiologies of sinoatrial

Tirzepatide and Cardiovascular Outcomes: A Narrative Review of Mechanisms, Efficacy and Implications for Heart Failure Management

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 1, January 2026.
Integrated framework for tirzepatide in HFpEF management. Through metabolic, haemodynamic, structural and anti‐inflammatory pathways, tirzepatide modifies the disease trajectory of HFpEF, leading to improvements in symptoms, functional capacity and reduction in HF events.

Simplified 2D Bidomain Model of Whole Heart Electrical Activity and ECG Generation

Measurement Science Review, 2014
The aim of this study was the development of a geometrically simple and highly computationally-efficient two dimensional (2D) biophysical model of whole heart electrical activity, incorporating spontaneous activation of the sinoatrial node (SAN), the ...
