Long QT syndrome is a heart rhythm disorder that can cause fast, chaotic heartbeats. In some cases, long QT syndrome can cause sudden death. Long QT syndrome may result from a genetic mutation or be caused by certain medications and medical conditions. The condition is treatable with medication, surgery, or an implantable device. Because it may have serious consequences, it’s important for electrophysiologists to know about long QT syndrome.

In this issue of Cardiac Electrophysiology Clinics, guest editors Drs. Emily Zeitler and Luigi Di Biase bring their considerable expertise to the topic of Case-Based Studies in Cardiac Electrophysiology. Top experts discuss various real-world cases in the field, including SVC tear; ICD extraction in LVAD patient; extraction and lead management in myotonic dystrophy; complex lead management decision making; extraction in patient with psLSVC; and more. - Contains 18 relevant, practice-oriented topics including multiple AF ablation cases; multiple pediatric/genetics EP cases; considerations for elective open extraction including debulking; lead management around structural heart interventions; and more. - Provides in-depth clinical reviews on case-based studies in cardiac electrophysiology, offering actionable insights for clinical practice. - Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.

This issue of Cardiology Clinics devoted to syncope, a disorder that is associated with increased mortality. Internationally recognized experts discuss the many causes of syncope, helping the clinician to distinguish life-threatening etiologies from benign ones.

This issue consists of 17 case studies, each involving a difficult decision that has to be made in the catheterization laboratory. Reading about the cases and seeing the ECGs will help cardiac electrophysiologists sharpen their clinical skills. The cases are also useful reading for those studying for board certification.

Controversies in Cardiac Electrophysiology are examined in this issue of Cardiac Electrophysiology Clinics. Difficult cases are presented and esteemed leaders in the field debate the pros and cons of various forms of management and treatment.

The sodium channel, a ubiquitous member of the cardiac, neural, and muscular conduction systems, has been implicated in the pathogenesis of an array of human diseases. Mutations associated with the cardiac sodium channel are responsible for a wide spectrum of disorders. The cardiac sodium channel and associated disorders are comprehensively examined in this issues of the Cardiac Electrophysiology Clinics.

This issue of Cardiac Electrophysiology Clinics, Guest Edited by Drs. Suneet Mittal and David Slotwiner,, is dedicated to Device-Based Arrhythmia Monitoring. This is one of four issues selected each year by the series Consulting Editors, Ranjan K. Thakur and Andrea Natale. Topics include, but are not limited to: Implantable loop recorders, Permanent pacemakers and implantable cardioverter defibrillators, Heart failure monitoring, Remote programming and cybersecurity concerns, Models for remote monitoring, Data management and integration with EMR systems, Screening for atrial fibrillation and The role of artificial intelligence in arrhythmia monitoring.

This issue of Cardiac Electrophysiology Clinics examines electrocardiography of complex arrhythmias. Topics include concealed conduction, right and left atrial macroreentrant tachycardias, focal atrial fachycardias, AV nodal and AV reentrant tachycardia, wide complex tachycardias, ventricular tachycardia in CAD, ECG characteristics of outflow tract VT, fascicular tachycardias, VT in non-ischemic dilated cardiomyopathy, VT originating from unusual sites, incessant VT and VT storms, ECG characteristics of TdP, VT in ARVC, and ventricular arrhythmia in inherited channelopathies, arrrhythmias in complex congenital heart disease, AV conduction disease and block, electrocardiographic analysis of paced rhythms.
