Ventricular ectopic beat detection using a wavelet transform and a convolutional neural network.

Physiol Meas 2019 Apr 10. Epub 2019 Apr 10.

Department of Biomedical Informatics, Emory University, 36 Eagle Row, #571, MS 2045-001-1AC, Atlanta, GA 30322, Atlanta, Georgia, UNITED STATES.

\emph{Objective:} Ventricular contractions in healthy individuals normally follow the contractions of atria to facilitate more efficient pump action and cardiac output. With a ventricular ectopic beat (VEB), volume within the ventricles are pumped to the body's vessels before receiving blood from atria, thus causing inefficient blood circulation. VEBs tend to cause perturbations in the instantaneous heart rate time series, making the analysis of heart rate variability inappropriate around such events, or requiring special treatment (such as signal averaging).

High density mapping of aortic cusps improves near field detection of pre-potentials during premature ventricular contractions.

J Electrocardiol 2019 Mar 7;54:47-48. Epub 2019 Mar 7.

Arrhythmology Unit - Ospedale S. Giovanni Calibita, Fatebenefratelli Isola Tiberina, Rome, Italy.

Recognition of pre-potentials during activation mapping of aortic cusp premature ventricular contractions is useful to localize the precise site of origin and is an indicator of successful ablation, but sometimes these electrograms can be blunt and have low amplitude. High resolution mapping in the aortic cusp region allows improved near field detection of these signals in very few beats. Read More

Department of Cardiovascular, Respiratory, Nephrology, Anaesthesiology and Geriatric Sciences of "Sapienza" University of Rome Rome Italy.

Delayed efficacy of radiofrequency energy can suppress ventricular arrhythmias after a failed ablation procedure. The implant of cardiac defibrillator for arrhythmia-induced cardiomyopathy should be procrastinated after a period of follow-up. Waiting for delayed efficacy is a reasonable choice to reduce the risk of complications associated with aggressive ablative approaches. 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

Increasing pace mapping properties in parahissian premature ventricular contraction. Novel insight from HD grid multipolar catheter.

J Arrhythm 2019 Feb 12;35(1):149-151. Epub 2018 Nov 12.

Arrhythmology Unit Ospedale S. Giovanni Calibita Fatebenefratelli Isola Tiberina Rome Italy.

A 23-year-old athlete with symptomatic low burden premature ventricular contraction (PVC) with left bundle branch block morphology and inferior axis morphology was sent to our department for RV mapping and PVC ablation. Exit zone of the PVC was easily and clearly defined by the bipoles A3-A4 achieving optimal and detailed pacemapping (Panels A-C) near the His bundle (yellow dots). The spatial conformation and the smooth shape of the catheter would definitely help everyday procedures in the setting of low burden PVC/noninducible focal ventricular arrhythmia, especially when the focus is located very close to the conductive tissue.

Coronary sinus as a site for stable temporary atrial pacing to tide over premature ventricular complex-triggered recurrent ventricular fibrillation in a patient with severe left ventricular dysfunction after coronary bypass surgery.

Indian Heart J 2018 Dec 21;70 Suppl 3:S483-S485. Epub 2018 Aug 21.

Cardiologist, Holy Family Hospital & Research Center, Mumbai, India. Electronic address:

Use of atrial pacing has been known, yet underutilized tool for effective temporary pacing whenever needed early after cardiac surgery. The reasons may be frequent failures of epicardial wires (fixed over atria intra-operative) leading to loss of capture. Endocardial atrial pacing sites for temporary pacing are unstable and hence continuous pacing with acceptable thresholds is impossible. Read More

Idiopathic short-coupled ventricular tachyarrhythmias: Systematic review and validation of electrocardiographic indices.

Egypt Heart J 2018 Dec 22;70(4):301-306. Epub 2018 Jun 22.

Prince Sultan Cardiac Centre, Military hospital, Riyadh, Saudi Arabia.

Introduction: Idiopathic short-coupled ventricular tachyarrhythmias make up a considerable proportion of ventricular tachyarrhythmias in structurally normal hearts and are the cause of 5-10% of unexpected sudden cardiac deaths. There is disparity in the literature regarding their description and a lack of formal diagnostic criteria to define them.

Objective: To validate ECG indices for the diagnosis of these ventricular tachyarrythmias and to subsequently unify their differing descriptions in the literature under a new terminology: . Read More

Vagus nerve stimulation reduces ventricular arrhythmias and increases ventricular electrical stability.

Pacing Clin Electrophysiol 2019 02 2;42(2):247-256. Epub 2019 Jan 2.

Xinjiang Key Laboratory of Medical Animal Model Research, Clinical Medical Research Institute, First Affiliated Hospital of Xinjiang Medical University, Urumqi, China.

Background: Transcutaneous stimulation of the auricular branch of the vagus nerve (AB-VNS) is a potentially noninvasive, inexpensive, and safe approach for vagus nerve stimulation that suppresses the induction and duration of atrial fibrillation and reduces sympathetic nerve outflow in healthy humans. Researchers have not determined whether AB-VNS affects ventricular arrhythmias.

Objective: To evaluate the antiarrhythmic effects of noninvasive AB-VNS on ventricular arrhythmias induced by myocardial infarction (MI). Read More
