    Prenatal diagnosis and prognosis of accelerate idioventricular rhythm.
    Ultrasound Obstet Gynecol 2016 Dec 10. Epub 2016 Dec 10.
    Fetal Cardiology Unit, Department of Pediatrics, CHU Sainte-Justine, (Université de Montréal), Québec, CANADA.
    Objectives: Since postnatal identification of accelerated idioventricular rhythm (AIVR) is essentially based on specific electrocardiographic patterns, its prenatal diagnosis is challenging and its genuine incidence undetermined. Therefore the objectives of this study are: 1) To evaluate the performance of specific ultrasonographic approaches in intrauterine identification of cardiocirculatory events linked to electrocardiographic signs of AIVR, including its left or right ventricular origin, and 2) To assess the prenatal prognosis of the arrhythmia.

    Methods: Doppler tracings in superior vena cava/ascending aorta, ductus venosus, ductus arteriosus and aortic isthmus as well as simultaneous M-mode recordings of septal and left ventricular wall motions of fetuses with the diagnosis of AIVR from 1 January 2004 to 31 December 2014 were reviewed.

    Is accelerated idioventricular rhythm a good marker for reperfusion after streptokinase?
    Indian Heart J 2016 May-Jun;68(3):302-5. Epub 2016 Jan 12.
    Professor and Head, Department of Cardiology, LTMMC & GH, Sion, Mumbai 22, India.
    Background: Accelerated idioventricular rhythm (AIVR) is a common arrhythmia observed in patients with ST segment elevation myocardial infarction (MI). It is not clear how much value AIVR has in predicting successful reperfusion, since there have been conflicting data regarding this in the past. Streptokinase (STK) even today is the commonest thrombolytic agent used in the public health care set-up in India. Read More

This case demonstrates the application of transthoracic echocardiography to guide anesthetic management in a parturient woman at risk for cardiovascular compromise. Read More

    Arrhythmias Seen in Baseline 24-Hour Holter ECG Recordings in Healthy Normal Volunteers During Phase 1 Clinical Trials.
    J Clin Pharmacol 2016 Jul 11;56(7):885-93. Epub 2016 Jan 11.
    Quintiles Cardiac Safety Services, Mumbai, India.
    Regulatory agencies encourage sponsors to submit 24-hour ambulatory ECG data for assessing cardiac safety of new drugs, and some arrhythmias, hitherto considered rare, have been observed in some early-phase studies. Interpretation of these observations is difficult given the dearth of published data on the prevalence of cardiac arrhythmias seen during 24-hour continuous ECG monitoring in healthy volunteers (HV) from clinical trials. We analyzed drug-free ambulatory ECG recordings from 1273 HV (1000 males, 273 females; age 18-65 years) from 22 phase 1 studies that were analyzed in a core ECG laboratory; all subjects had normal screening ECGs.

    Postconditioning attenuates early ventricular arrhythmias in patients with high-risk ST-segment elevation myocardial infarction.
    J Cardiol 2015 Jun 29;65(6):459-65. Epub 2015 Mar 29.
    1st Department of Cardiology, University of Medical Sciences, Poznan, Poland.
    Background: It has been demonstrated that postconditioning (postcon), brief episodes of ischemia during reperfusion period, in patients with ST-segment elevation myocardial infarction (STEMI) confers protection against ischemia-reperfusion injury and as a result, postcon might reduce infarct size. However, whether postcon may exert its beneficial effect on STEMI patients by reducing the occurrence of early malignant ventricular arrhythmias (VA) is still unknown. The aim of the study was to evaluate the influence of postcon on the presence of VA in early presenters with high-risk STEMI treated with primary coronary intervention (PCI). Read More

    Ectopic automaticity induced in ventricular myocytes by transgenic overexpression of HCN2.
    J Mol Cell Cardiol 2015 Mar 3;80:81-9. Epub 2015 Jan 3.
    Department of Physiology, Kurume University School of Medicine, Kurume, Japan. Electronic address:
    Hyperpolarization-activated cyclic nucleotide-gated channels (HCNs) are expressed in the ventricles of fetal hearts but are normally down-regulated as development progresses. In the hypertrophied heart, however, these channels are re-expressed and generate a hyperpolarization-activated, nonselective cation current (Ih), which evidence suggests may increase susceptibility to arrhythmia. To test this hypothesis, we generated and analyzed transgenic mice overexpressing HCN2 specifically in their hearts (HCN2-Tg). Read More

    Transient post-reperfusion left bundle branch block and accelerated idioventricular rhythm with paradoxical QRS narrowing.
    J Electrocardiol 2014 Sep-Oct;47(5):705-7. Epub 2014 May 6.
    Christus St. Vincent Hospital, Santa Fe, NM; Department of Medicine University of New Mexico Albuquerque, NM.
    Accelerated idioventricular rhythm (AIVR) commonly follows coronary reperfusion and has been called a "reperfusion arrhythmia". Transient left bundle branch block (LBBB) is only rarely seen after interventional reperfusion and is usually considered a procedural complication. We report herein electrocardiograms (ECGs) in a case of acute lateral myocardial infarction which demonstrate both post-perfusion AIVR and a simultaneous transient LBBB with fusion complexes causing paradoxical QRS narrowing.

    Grouped beating in eisenmenger: successful localization and ablation of an accelerated idioventricular rhythm from within the purkinje system.
    Indian Pacing Electrophysiol J 2013 May 25;13(3):126-30. Epub 2013 Jun 25.
    Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom.
    A 33-year old female with a background of Eisenmenger syndrome secondary to multiple congenital muscular ventricular septal defects (VSD) was admitted with a recent history of frequent intermittent palpitations. It was noted that she had an independent accelerated idioventricular rhythm (AIVR), with rates varying between 85-110bpm, which exhibited a repetitive grouped beating pattern. Although generally perceived as benign, in this case this rhythm was drug refractory, was associated with significant compromise to cardiac filling and output and progressed to haemodynamically intolerable sustained ventricular tachyarrhythmia.
