Role of concealed conduction and allied phenomena in the genesis, maintenance, and termination of cardiac arrhythmias.

Pacing Clin Electrophysiol 2019 Apr 16. Epub 2019 Apr 16.

Heart and Vascular Team, Bellin Health, 744 South Webster Ave, Green Bay, Wisconsin, 54305.

Concealed conduction is a common electrocardiographic phenomenon whereby a series of events may occur as a result of incomplete propagation of an impulse. The occurrence, maintenance, and resolution (termination) of several events such as functional block and cardiac arrhythmias are linked to concealed conduction. This phenomenon should be suspected on the surface ECG whenever an arrhythmic event occurs unexpectedly. Read More

A large deletion in RYR2 exon 3 is associated with nadolol and flecainide refractory catecholaminergic polymorphic ventricular tachycardia.

Pacing Clin Electrophysiol 2019 Mar 25. Epub 2019 Mar 25.

Center for Arrhythmia Care, Heart & Vascular Center, Pritzker School of Medicine of the University of Chicago, Chicago, Illinois.

We report a 17-year-old boy with a large RYR2 exon 3 deletion who has a severe catecholaminergic polymorphic ventricular tachycardia (CPVT) phenotype characterized by refractoriness to both nadolol and flecainide which has previously not been reported in this subgroup of CPVT patients. Treatment options in a patient like ours are therefore limited and sympathectomy and implantable cardioverter-defibrillator implantation should be considered early in the treatment course as was done in this patient. In contrast to other CPVT patients who do not usually have structural cardiac abnormalities, these patients are at a high risk of developing left ventricular noncompaction or dilated cardiomyopathy and therefore might benefit from cardiac imaging at regular intervals.

Optimal cutoff value of bipolar low-voltage in electroanatomic voltage mapping during atrial fibrillation rhythm.

Pacing Clin Electrophysiol 2019 Mar 15. Epub 2019 Mar 15.

Department of Cardiology, Mitsubishi Kyoto Hospital, Kyoto, Japan.

Background: Electroanatomic voltage mapping (EAVM) of the left atrium (LA) with multielectrodes is usually acquired during sinus rhythm (SR), and the feasibility of EAVM during atrial fibrillation (AF) rhythm is unclear.

Methods: We performed EAVM of LA during both SR and AF rhythm in 44 patients undergoing catheter ablation for AF and validated the optimal cutoff value of low-voltage area (LVA) during AF rhythm for detecting LVA defined as bipolar voltages ≤0.5 mV during SR. Read More

Evaluation of an Internet-based intervention for ICD patients with elevated symptoms of posttraumatic stress disorder.

Pacing Clin Electrophysiol 2019 Mar 7. Epub 2019 Mar 7.

Department of Psychology, East Carolina University, Greenville, North Carolina.

Background: To date, treatment to reduce posttraumatic stress disorder (PTSD) symptoms in implantable cardioverter defibrillator (ICD) patients has been limited by lack of symptom recognition, lack of provider referrals, barriers to treatment access, and inadequate evidence base of treatment effectiveness in this population.

Methods: Participants were 46 patients with ICDs (17 paired) with elevated PTSD symptoms who were recruited in electrophysiology clinics at community and university hospitals as well as ICD support forums. Participants were provided the Web-based, brief psychosocial intervention, which was tailored to ICD patients and contained elements of evidence-based cognitive-behavioral protocols for PTSD.

Interlead electrical delays and scar tissue: Response to cardiac resynchronization therapy in patients with ischemic cardiomyopathy.

Pacing Clin Electrophysiol 2019 Mar 6. Epub 2019 Mar 6.

Department of Cardiology, Copenhagen University Hospital, Rigshospitalet, Copenhagen, Denmark.

Background: The importance of interlead electrical delays (IEDs) in the presence of scar tissue for response to cardiac resynchronization therapy (CRT) in patients with ischemic cardiomyopathy is poorly described.

Methods: Sixty-eight CRT patients with ischemic cardiomyopathy and left bundle branch block were included. IEDs, the time between sensing of native impulse at the RV lead and LV lead, were measured at implantation and after 8 months. Read More
