The autonomic nervous system plays a significant role in the genesis and maintenance of ventricular arrhythmias (VAs) and powerfully modulates the underlying substrate in a dynamic manner. Blockade of the sympathetic nervous system, whether through medications or neuraxial modulation, has…
Introduction Despite significant advances in the diagnosis and treatment of malignant cardiac arrhythmias, sudden cardiac death (SCD) occurs in 180,000 to 250,000 people annually, mostly in patients with coronary artery disease. Myocardial infarction (MI) remains a vulnerable cardiac pathology that…
Key Points Radiofrequency (RF) energy is the most commonly used energy source in cardiac catheter ablation procedures. The goal of RF power titration is to maximize the safety and efficacy of energy application. Stable catheter-tissue contact is inadequately assessed by…
Additional content is available online at Elsevier eBooks for Practicing Clinicians The critical role of a balanced autonomic nervous system for appropriate function and responsiveness of the cardiovascular system is often overlooked. The interrelationship of these two systems is often…
