Flecainide: electrophysiological properties, clinical indications, and practical aspects

Publication date: Available online 4 September 2019Source: Pharmacological ResearchAuthor(s): Enrico Paolini, Giulia Stronati, Federico Guerra, Alessandro CapucciAbstractOver the last 35 years, flecainide proved itself one of the most commonly used arrhythmic drugs, expanding its original indication for ventricular arrhythmias and results nowadays as the cornerstone of the rhythm control strategy in atrial fibrillation management of patients without structural heart disease. While the increased mortality associated with flecainide in the Cardiac Arrhythmia Suppression Trial (CAST) still casts his shadow over flecainide clinical profile, this compound has subsequently demonstrated safe and is now used successfully for a plethora of indications, including pharmacological cardioversion of atrial fibrillation, cathecolaminergic polymorphic ventricular tachycardia, supraventricular tachyarrhythmias and ventricular pre-excitation.Moreover, the recent marketing of a controlled release formulation, along with the intravenous and immediate release formulations, increased the armamentarium to the clinician’s disposal while improving patients’ compliance.In the present paper, we offer a comprehensive review of the anti-arrhythmic effects of flecainide, detailing its electrophysiological properties, its effects on the conduction system, its clinical use and the major side effects and contraindications in clinical practice.Graphical abstract

ConclusionIn this small hypothesis generating study low levels of SA were associated with the occurrence of NOAF. It remains to be shown if increasing SA levels lowers the incidence of NOAF.

Confabulation of a confused cardiologist Yes, It has never bothered me to retrogradely cross a delicately dangerous epicardial collateral in complex CTO. Delivering a twin stent in a partial culotte strategy for a bifurc lesion has never tested my talents. Stenting a left main across the LAD, jailing the LCX with OCT support is my favorite time pass. Crushing a calcium infested diffuse long lesion with diamond-tipped ablator appear as breezy as shopping in a mall. Oh …I am terribly upset with this damn thing.  What is that? It requires 4 negative forces . . . to bring one big positive Impact! These studies say ...

Conclusion: Chinese women had a substantially lower risk of venous thromboembolism during pregnancy and the postpartum period compared to that of Caucasians. The occurrence of pregnancy-related venous thromboembolism was largely confined to the early pregnancy period, probably related to the adoption of thromboprophylaxis, a lower rate of Cesarean section, and early mobilization.

(Children's Hospital of Philadelphia) The largest-ever clinical trial of a medication for pediatric cardiology patients found that an oral drug significantly improved exercise capacity in adolescent patients with severe, congenital single-ventricle heart defects. A study leader says the physiologic benefits represent a milestone in the care of those who have undergone the Fontan procedure, a palliative operation for single-ventricle disease.

Arrhythmias are common in horses. Sinus arrhythmia and first- and second-degree atrioventricular block are frequently found physiologic arrhythmias, but should immediately disappear after stress or exercise. Atrial premature depolarizations are usually not associated with poor performance, but are a potential trigger for atrial fibrillation. Atrial fibrillation results in an abnormal ventricular response during exercise and poses a risk for collapse in some horses. This arrhythmia can usually be treated by quinidine sulfate or transvenous electrical cardioversion. Ventricular premature depolarizations, especially when asso...

This study found that though it is often associated with coronary artery disease (CAD), it can also occur in those without significant CAD. It was not specifically associated with disease of right coronary artery disease. This cardioinhibitory response may be a manifestation of the Bezold-Jarisch reflex. Bezold-Jarisch reflex inhibits sympathetic activity (sympathetic withdrawal) and increases parasympathetic activity, resulting in bradycardia, which may be associated with vasodilatation, nausea and hypotension. Bezold-Jarisch has been described in the setting of inferior wall infarction and coronary angiography. Origin...
