The Development of Innovative Handheld Devices to Augment Cardiopulmonary Resuscitation Therapy and External Cardioversion and Defibrillation.

J Innov Card Rhythm Manag 2017 Dec 15;8(12):2930-2938. Epub 2017 Dec 15.

NYU Winthrop Hospital, Mineola, NY, USA.

Active compression-decompression (ACD) cardiopulmonary resuscitation (CPR) devices were conceived and invented by Drs. Todd Cohen and Keith Lurie to improve the low survival rates for conventional CPR. Active decompression creates greater chest recoil as compared with the passive decompression used in standard CPR, leading to increased preload and greater cardiac output. Read More

Phase Entrainment of Induced Ventricular Fibrillation: A Human Feasibility and Proof of Concept Study.

J Atr Fibrillation 2019 Dec 31;12(4):2217. Epub 2019 Dec 31.

West Yorkshire Arrhythmia Service, Leeds General Infirmary, Great George Street, Leeds, LS1 3EX, UK.

Cardioversion and defibrillation by a single high energy shock applied by myocardial or body surface electrodes is painful, causes long term tissue damage, and is associated with worsening long term outcomes, but is almost always required for treatment of ventricular fibrillation . As a initial step towards developing methods that can terminate ventricular arrhythmias painlessly, we aim to determine if pacing stimuli at a rate of 5/s applied via an implantable cardiac defibrillator (ICD) can modify human ventricular fibrillation. In 8 patients undergoing defibrillation testing of a new/exchanged intracardiac defibrillator, five seconds of pacing at five stimuli per second was applied during the 10-20 seconds of induced ventricular fibrillation before the defibrillation shock was automatically applied, and the cardiac electrograms recorded and analyzed.

Cardioversion of Atrial Fibrillation and Flutter: Comparative Study of Pulsed vs. Low Energy Biphasic Truncated Exponential Waveforms.

J Atr Fibrillation 2019 Oct-Nov;12(3):2172. Epub 2019 Oct 31.

Institute of Biophysics and Biomedical Engineering, Bulgarian Academy of Sciences, Acad. G. Bonchev Str, Bl. 105, 1113 Sofia, Bulgaria.

Background: Despite the widespread use of biphasic waveforms for cardioversion and defibrillation, the efficacy and safety of shocks has only been compared in a few studies.

Methods: This retrospective study aims at comparing the efficacy and safety of biphasic truncated exponential (BTE) pulsed energy (PE) waveform with a BTE low energy (LE) waveform for cardioversion of atrial fibrillation (AF) and atrial flutter (AFL). The treatment energies were following an escalating protocol for PE waveform (120-200-200J in AF and 30-120-200J in AFL) and LE waveform (100-200-200J in AF and 30-100-200J in AFL). Read More

Real-time feedback improves chest compression quality in out-of-hospital cardiac arrest: A prospective cohort study.

PLoS One 2020 24;15(2):e0229431. Epub 2020 Feb 24.

Department of Anaesthesiology, Intensive Care and Pain Medicine, Münster University Hospital, Münster, Germany.

Background: Current guidelines underline the importance of high-quality chest compression during cardiopulmonary resuscitation (CPR), to improve outcomes. Contrary to this many studies show that chest compression is often carried out poorly in clinical practice, and long interruptions in compression are observed. This prospective cohort study aimed to analyse whether chest compression quality changes when a real-time feedback system is used to provide simultaneous audiovisual feedback on chest compression quality.

Automatic implantable cardioverter defibrillator: when not to implant.

Monaldi Arch Chest Dis 2020 Feb 21;90(1). Epub 2020 Feb 21.

Department of Cardiology, Istituti Clinici Scientifici Maugeri IRCCS, Institute of Montescano (PV).

The implantable cardioverter-defibrillator (ICD) is the mainstay therapy for primary prevention of sudden cardiac death in patients with heart failure with a reduced ejection fraction. Current indications for prophylactic ICD are based on the results of randomized controlled trials dating back to 15-20 years ago, which have usually enrolled highly selected patients with few comorbidities and only a small number of patients aged >75 years. Existing literature suggest an age-dependent attenuation of the efficacy of the ICD. Read More

[Electrical storm : Recognition and management].

Herzschrittmacherther Elektrophysiol 2020 Mar 14;31(1):55-63. Epub 2020 Feb 14.

Klinikum Lüdenscheid, Klinik für Kardiologie, Elektrophysiologie und Angiologie, Märkische Kliniken GmbH, Paulmannshöherstraße 10-14, 58515, Lüdenscheid, Deutschland.

The electrical storm (ES) defined as ≥3 sustained episodes of ventricular tachycardia within a 24 h period comprises a wide spectrum of clinical entities. Mostly patients suffer from severe heart insufficiency and comorbidities making an immediate transfer into a heart center with multidisciplinary expertise in the treatment of ES mandatory. As these patients are often traumatized by ongoing tachycardia despite multiple cardioversions, early deep sedation and β‑blockade to break the vicious circle of sympathico-adrenergic hyperactivation is very effective.

Klinik für Interventionelle Elektrophysiologie, Rhön-Klinikum Campus Bad Neustadt, Von-Guttenberg-Str. 11, 97616, Bad Neustadt a. d. Saale, Germany.

Acute management of patients with ventricular arrhythmia (VA) is aimed at immediate VA termination if the patient is hemodynamically instable and early termination after initial diagnostic work-up if tolerated. Prolonged episodes of VA may lead to hemodynamic and metabolic decompensation and early resumption of normal ventricular activation is warranted. Termination is best performed by electrical cardioversion, anti-tachycardia pacing (if available, in cases with an implanted defibrillator [ICD]) or defibrillation. Read More

Outcomes following cardioversion for patients with cardiac amyloidosis and atrial fibrillation or atrial flutter.

Am Heart J 2020 04 8;222:26-29. Epub 2020 Jan 8.

Division of Cardiovascular Disease, Duke University Medical Center, Durham, NC. Electronic address:

Atrial arrhythmias commonly occur in patients with cardiac amyloidosis (CA), but there is limited data on safety or efficacy of cardioversion (DCCV) for management of these rhythms in CA. We identified 25 patients with CA (20 with transthyretin (TTR) and 5 with light-chain (AL) amyloidosis) at Duke University who underwent DCCV for atrial arrhythmias and documented procedural success, complications, and long-term morbidity and mortality. While DCCV successfully restored sinus rhythm in 96% of patients, 36% of patients experienced immediate procedural complications (primarily bradycardia and hypotension), 80% had recurrence of atrial arrhythmias at 1 year, and 52% died at 3 years, highlighting short-term safety concerns, long-term inefficacy, and poor prognosis associated with symptomatic atrial arrhythmias requiring DCCV in CA.

A Numerical Evaluation of Multi-Lead Subcutaneous Implantable Cardioverter Defibrillator for Low Energy and Less Damage in Swine

Conf Proc IEEE Eng Med Biol Soc 2019 07;2019:4889-4892

In the rescue of patients with sudden cardiac death, cardiac electric defibrillation is usually implemented, but the myocardial damage caused by exceeding defibrillation shock is irreversible. The aim of this study is to provide a numerically implanted optimization of a subcutaneous implantable cardioverter defibrillator (S-ICD) for low shock energy and less myocardial damage. In this paper, three anatomically realistic finite element models of swine were constructed for the evaluation study of six Can-Lead configurations with various number of leads at different placements.

Outcomes during and after the use of the wearable cardioverter-defibrillator in a tertiary-care and a regional hospital in Switzerland.

Swiss Med Wkly 2019 11 10;149:w20136. Epub 2019 Nov 10.

Department of Cardiology, University Hospital of Zurich, Switzerland/ Centre for Integrative Human Physiology, University of Zurich, Switzerland.

Introduction: The wearable cardioverter-defibrillator (WCD) has established itself in treatment of potentially life-threatening ventricular arrhythmias, when implantation of an implantable cardioverter-defibrillator (ICD) is not warranted. Careful patient selection for this therapy is crucial, but unfortunately very little information from randomised controlled trials is available to guide clinical decision-making. Consequently, data from real-world patient registries play a more important role in this context. Read More

[The subcutaneous implantable cardioverter-defibrillator in clinical practice].

G Ital Cardiol (Rome) 2019 Nov;20(11):641-650

Dipartimento Cardio-Toraco-Vascolare, Università degli Studi, Padova.

Overcoming lead-related complications, the subcutaneous implantable cardioverter-defibrillator (S-ICD) represents the greatest advancement in the management of patients with ventricular arrhythmias and the prevention of sudden cardiac death. Due to the absence of leads within the body, the S-ICD requires an innovative approach for sensing of subcutaneous signals and defibrillation. The aim of this review is to analyze the current evidence regarding patient selection, technical aspects such as the implant technique, programming and follow-up, as well as complications and troubleshooting of this innovative technology.

Trends and Outcomes of Atrial Fibrillation-Flutter Hospitalizations Among Heart Transplant Recipients (From the National Inpatient Sample).

Am J Cardiol 2020 01 10;125(1):87-91. Epub 2019 Oct 10.

Division of Cardiovascular Diseases, Section of Heart Failure and Transplant, University of Iowa Hospitals and Clinics, Iowa City, Iowa. Electronic address:

Atrial fibrillation-flutter (AF) has been described in 10% to 24% of patients after heart transplant (HT). Data on AF hospitalizations after HT are limited to single-center experiences. To bridge this gap, we performed an analysis of admissions for AF in HT patients from the National Inpatient Sample (NIS) years 2000 to 2014. Read More

Ventricular Tachycardia Storm After Standard Radiofrequency Pulmonary Vein Isolation.

Am J Case Rep 2019 Oct 19;20:1536-1539. Epub 2019 Oct 19.

Heart and Vascular Center, Mater Private Hospital, Dublin, Ireland.

BACKGROUND The occurrence of ventricular arrhythmias (VAs), particularly premature ventricular complexes, following pulmonary vein isolation (PVI) is a documented phenomenon, but monomorphic scar-related ventricular tachycardia (VT) following PVI is an unusual phenomenon. In this case report, we present a case of new-onset VA after radiofrequency PVI in a patient with no prior history of sustained VTs. CASE REPORT Our patient was a 69-year-old man with a history of symptomatic persistent atrial fibrillation, with an apparently structurally normal heart with subtle regional wall motion abnormalities.

Periprocedural Anticoagulation for Cardioversion of Acute Onset Atrial Fibrillation and Flutter: Evidence Base for Current Guidelines.

Can J Cardiol 2019 10 12;35(10):1301-1310. Epub 2019 Jun 12.

Department of Cardiac Sciences, Libin Cardiovascular Institute of Alberta, University of Calgary and Alberta Health Services, Calgary, Alberta, Canada.

The practice of electrical or pharmacological cardioversion (CV) to restore sinus rhythm in patents with symptomatic atrial fibrillation (AF) or atrial flutter has been a part of clinical practice for more than 100 years. For almost as long as CV has been performed, it has been recognized that the act of restoring sinus rhythm is associated with an increased risk of stroke and systemic embolism, and that oral anticoagulant (OAC) therapy can be used to prevent peri-CV thromboembolism. Although it has been widely accepted that OAC therapy is necessary to prevent thromboembolism in patients with chronic AF/atrial flutter who undergo CV, previous clinical practice recommendations have suggested that OAC therapy may be omitted in patients at low risk of stroke.
