Cryoballoon ablation of focal atrial tachycardia originating from right atrial appendage: Case report and review of the literature.

Indian Pacing Electrophysiol J 2019 Apr 11. Epub 2019 Apr 11.

Hacettepe University Faculty of Medicine, Department of Cardiology, Arrhythmia and Electrophysiology Unit, Ankara, Turkey.

The right atrial appendage (RAA) is a rare site of focal atrial tachycardia (AT). Sometimes, catheter ablation cannot successfully be accomplished at this location due to the difficulty in reaching the exact ablation site as well as the associated possible life-threatening complications like pericardial tamponade or perforation. Although radiofrequency (RF) ablation is preferred for the treatment of RAA tachycardias, alternative tools may be required in rare instances. Read More

Late elimination of challenging idiopathic ventricular arrhythmias originating from left ventricular summit by anatomical ablation.

Indian Pacing Electrophysiol J 2019 Feb 26. Epub 2019 Feb 26.

Ankara University, Cardiology Department, Ankara, Turkiye.

Ablation of premature ventricular complexes (PVCs) originating from left ventricular outflow tract (LVOT)/left ventricular summit (LVS) is challenging with considerable rate of failure. Recently, in a novel approach to ablation of these arrythmias, application of radiofrequency energy to anatomically opposite sites of presumed origin of arrythmia, has been associated with moderate procedure success. Although late elimination of PVCs that are persistent following an ablation procedure has been previously reported, this observation has not been studied sufficiently. Read More

Epsilon wave: A review of historical aspects.

Indian Pacing Electrophysiol J 2019 Mar - Apr;19(2):63-67. Epub 2019 Feb 21.

Sarver Heart Center, The University of Arizona Health Sciences Hospital, Tucson, AZ, USA.

The epsilon wave of the electrocardiogram (ECG) together with fragmented QRS (fQRS), the terminal conduction delay, incomplete right bundle branch block (IRBBB) and complete/advanced RBBB (CRBBB) of peripheral origin are part of a spectrum of ventricular depolarization abnormalities of arrhythmogenic cardiomyopathy(AC). Although the epsilon wave is considered a major diagnostic criterion for AC since 2010 (AC Task Force Criteria), its diagnostic value is limited because it is a sign of the later stage of the disease. It would be more appropriate to say that the epsilon wave is a "hallmark" of AC, but is of low diagnostic sensitivity. Read More

San Antonio Military Medical Center, Electrophysiology Division, Cardiology Section, 3551 Roger Brooke Drive, San Antonio, TX, 78234, USA.

Anti-arrhythmic drugs (AADs) uniquely affect the various electrolyte channels in the heart and can slow conduction, increase refractoriness, and/or decrease automaticity with the goal of preventing tachyarrhythmias. Due to these properties, these same drugs are by nature pro-arrhythmic. Vaughan-Williams classification Ic AADs belong to a class of medications that inhibit sodium channels, leading to decreased conduction velocity of myocytes and Purkinje fibers as well as to decreased automaticity of pacemaker cells.

Venoplasty of a chronic venous occlusion with 'diathermy' for cardiac device lead placement.

Indian Pacing Electrophysiol J 2019 Jan - Feb;19(1):27-29. Epub 2018 Oct 25.

Division of Cardiac Electrophysiology, Department of Cardiology, Madinah Cardiac Centre, Madinah, Saudi Arabia.

Venous revascularization is an approach used in patients with total venous occlusion requiring venous access for cardiac device lead placement. Several percutaneous approaches to venous revascularization have been proposed. For the first time, we describe the case of a 69-year-old male with total venous occlusion who was successfully revascularized using a 'diathermy' technique. Read More

Left posterior fascicular block, state-of-the-art review: A 2018 update.

Indian Pacing Electrophysiol J 2018 Nov - Dec;18(6):217-230. Epub 2018 Oct 13.

Heart Center, Tampere University Hospital and Faculty of Medicine and Life Sciences, University of Tampere, Finland.

We conducted a review of the literature regarding epidemiology, clinical, electrocardiographic and vectorcardiographic aspects, classification, and differential diagnosis of left posterior fascicular block. Isolated left posterior fascicular block (LPFB) is an extremely rare finding both in the general population and in specific patient groups. In isolated LPFB 20% of the vectorcardiographic (VCG) QRS loop is located in the right inferior quadrant and when associated with right bundle branch block (RBBB) ≥40%. Read More

Repeat ablation for paroxysmal atrial fibrillation - Does adenosine play a role in predicting pulmonary vein reconnection patterns?

Indian Pacing Electrophysiol J 2018 Nov - Dec;18(6):203-207. Epub 2018 Oct 2.

Department of Electrophysiology, German Heart Center Munich, Technische Universitaet Munich, Germany.

Background: Pulmonary vein (PV) reconduction after PV isolation (PVI) unmasked by adenosine is associated with a higher risk for paroxysmal atrial fibrillation (PAF) recurrence. It is unknown if the reconnected PVs after adenosine testing and immediate re-ablation can predict reconnection and reconnection patterns of PVs at repeat procedures. We assessed reconnection of PVs with and without dormant-conduction (DC) during the first and the repeat procedure. Read More

Trends in implantable cardioverter defibrillator and cardiac resynchronisation therapy lead parameters for patients with arrhythmogenic and dilated cardiomyopathies.

Indian Pacing Electrophysiol J 2019 Mar - Apr;19(2):49-54. Epub 2018 Aug 23.

Department of Cardiac Electrophysiology, Barts Heart Centre, St Bartholomew's Hospital, West Smithfield, London, EC1A 7BE, United Kingdom; Department of Cardiac Electrophysiology, Heart Hospital, 16-18 Westmoreland St, Marylebone, London, W1G 8PH, United Kingdom.

Background: Implantable cardioverter-defibrillator (ICD) lead parameters may deteriorate due to right ventricular (RV) disease such as arrhythmogenic right ventricular cardiomyopathy (ARVC), with implications for safe delivery of therapies. We compared ICD and CRT-D (cardiac resynchronisation therapy-defibrillator) lead parameters in patients with ARVC and dilated cardiomyopathy (DCM).

Methods: RV lead sensing (R wave amplitude) and pacing (threshold and amplitude-pulse width product (APWP)), left ventricular (LV) pacing (APWP), and imaging parameter trends were assessed in 18 patients with ARVC and 18 with DCM. Read More

Correlation of pacing site in right ventricle with paced QRS complex duration.

Indian Pacing Electrophysiol J 2018 Nov - Dec;18(6):210-216. Epub 2018 Aug 17.

Department of Cardiology, All India Institute of Medical Sciences, New Delhi, India.

Background: Pacing from RV mid septum and outflow tract septum has been proposed as a more physiological site of pacing and narrower paced QRS complex duration. The paced QRS morphology and duration in different RV pacing sites is under continued discussion. Hence, this study was designed to address the correlation of pacing sites in right ventricle with paced QRS complex duration. Read More

Usefulness of a lead delivery system consisting of a fixed-shaped sheath and a lumenless bipolar lead in a patient with absent right and persistent left superior vena cava: A case report.

Indian Pacing Electrophysiol J 2018 Nov - Dec;18(6):234-236. Epub 2018 Aug 16.

Department of Respiratory and Cardiovascular Medicine, Odate Municipal General Hospital, Japan.

We report the case of an 84-year-old female with symptomatic bradycardia due to a complete atrioventricular block, who carried absent right and persistent left superior vena cava (SVC). Implantation of a pacing lead, particularly within the right ventricle (RV) in a patient with this venous anomaly is accompanied by technical difficulties. However, the apparatus consisting of a fixed-curve sheath (Model C315-S10, Medtronic, Inc. Read More

Cardiac resynchronization therapy pacemakers versus defibrillators in older non-ischemic cardiomyopathy patients.

Indian Pacing Electrophysiol J 2019 Jan - Feb;19(1):4-6. Epub 2018 Aug 16.

Heart and Vascular Institute, University of Pittsburgh Medical Center, Pittsburgh, PA, USA. Electronic address:

Introduction: With the recent publication of the negative DANISH trial, the mortality benefit of the implantable cardioverter-defibrillator (ICD) has been put in question in patients with non-ischemic cardiomyopathy (NICM). Because a majority of patients in DANISH receive cardiac resynchronization therapy (CRT) devices, we investigated in the present study the survival of recipients of CRT pacemakers (CRT-P) versus CRT ICDs (CRT-D) in a cohort of older (≥75 years) NICM patients at our institution.

Methods: A total of 135 NICM patients with CRT device were identified (42 with CRT-P and 93 with CRT-D) and were followed to the endpoint of all-cause mortality. Read More

Department of Cardiovascular Diseases, Mayo Clinic, Rochester, MN, USA; Department of Pediatrics and Adolescent Medicine, Mayo Clinic, Rochester, MN, USA. Electronic address:

Introduction: The His-Purkinje system has been shown to harbor triggers for ventricular fibrillation (VF) initiation. However, the substrate responsible for VF maintenance remains elusive. We hypothesized that standard, electrode-based, point-to-point mapping would yield meaningful insight into site-specific patterns and organization which may shed light on the critical substrate for maintenance of VF.
