Transvenous Lead Extractions: Current Approaches and Future Trends

The use of cardiovascular implantable electronic devices (CIEDs) has increased dramatically, with approximately 1.2–­1.4 million CIEDs implanted annually worldwide.1 In the US alone, there are more patients with CIEDs than registered nurses.2,3 CIEDs use leads that connect a generator to cardiac tissue to treat patients with many conditions including symptomatic bradycardia, morbid tachycardia and advanced heart failure.

Heart Rate Variability: An Old Metric with New Meaning in the Era of using mHealth Technologies for Health and Exercise Training Guidance. Part One: Physiology and Methods

Considerable evidence supports the importance that the autonomic nervous system (ANS) has regarding cardiovascular health and prognosis.1 Specific variables derived from heart rate (HR) and heart rate variability (HRV) at rest and with exercise help assess the status of the ANS. Interest has also peaked on the use of HRV to assess the quality of an exercise programme. Among the athletic population, HRV has been recommended to warn of over-training and to optimise performance.

Practical Guide to Ablation for Epicardial Ventricular Tachycardia: When to Get Access, How to Deal with Anticoagulation and How to Prevent Complications

Ventricular tachycardia (VT) is one of the most challenging medical conditions faced by cardiac patients and physicians treating them. Antiarrhythmic medications have limited effectiveness and are frequently poorly tolerated.1–4 Catheter ablation is increasingly used to treat patients successfully.1,5–7 Most VTs can be ablated endocardially but some require epicardial mapping and ablation.
