Experimental and clinical studies have demonstrated that enhanced sympathetic autonomic nervous system (SANS) activity can destabilise myocardial repolarisation,1–4 increasing vulnerability to developing fatal cardiac arrhythmias.5–8 Accordingly, assessment of SANS activity has always been a major goal for cardiac risk stratification methods. Various non-invasive methods including assessment of… View more

Is There a Future for Remote Cardiac Implantable Electronic Device Management?
Author(s): Haran Burri Added: 3 years ago
Remote follow-up and monitoring of patients implanted with cardiac implantable electronic devices (CIEDs) has been introduced over a decade ago, and is now indicated according to European (class IIa indication1) and American (class I indication2) guidelines. There have been high expectations that this technology will improve patient outcome, as it significantly shortens response to actionable… View more

Since the 1960s, Holter monitoring has been a cornerstone for diagnosing suspected arrhythmias in patients of all ages.1 The most common monitoring systems allow the continuous registration of three or more leads for 24–48 hours; newer Holter monitors allow continuous electrocardiogram (ECG) registration for 2 weeks.1 Extending the time of ECG registration will increase the diagnostic yield of… View more

The plasticity of the heart enables it to adapt to certain pathological insults and to maintain the cardiac output necessary to satisfy the metabolic requirements of the body.1 Although beneficial at first, this process of ventricular remodelling can have detrimental effects on cardiac function and contribute to arrhythmogenesis.2 Sudden cardiac death due to ventricular tachyarrhythmias accounts… View more

The interplay between the central nervous system and cardiac electrophysiology is fundamental, and becomes obvious each time one’s pulse quickens in response to stress. Normally, cardiac neurohormonal regulation is accomplished through the balanced effects of sympathetic and parasympathetic autonomic stimulation, along with the hormonal regulation of the renin-angiotensinaldosterone system (RAAS)… View more

There are numerous conglomerations of autonomic ganglia on the epicardial surface of the heart, known as ganglionated plexi (GP). These GP have been shown to play a significant role in different arrhythmias, including AF. As such, GP ablation has become an adjunctive procedure in the treatment of AF. This review will present the current data on the significance of GP in arrhythmogenesis and will… View more

Despite the clear improvements in clinical outcomes brought about by medical therapy with β-blockers, ACE inhibitors and aldosterone antagonists, as well as by device therapy with cardiac resynchronisation, many patients with chronic heart failure (HF) remain symptomatic despite optimal medical therapy. Symptomatic HF can have devastating consequences for the quality of life of individuals, and… View more

Upstream Treatment of Atrial Fibrillation with n-3 Polyunsaturated Fatty Acids: Myth or Reality?
Author(s): Francesco Orso , Gianna Fabbri , Aldo Pietro Maggioni Added: 3 years ago
Atrial fibrillation (AF) is the most common sustained arrhythmia in adults and confers increased risk of death,1 thromboembolism and impaired quality of life.2 Current pharmacological antiarrhythmic drugs provide limited protection against AF recurrence and have poor safety profiles, while invasive ablation treatments are associated with significant risks and limited long-term success rates… View more
