Background Early defibrillation plays a key role in improving survival in patients with out-of-hospital cardiac arrests due to ventricular fibrillation (ventricular-fibrillation cardiac arrests), and the use of publicly accessible automated external defibrillators (AEDs) can help to reduce the time to defibrillation for such patients. However, the effect of dissemination of public-access AEDs for ventricular-fibrillation cardiac arrest at the population level has not been extensively investigated. Methods From a nationwide, prospective, population-based registry of patients with out-of-hospital cardiac arrest in Japan, we identified patients from 2005 through 2013 with bystander-witnessed ventricular-fibrillation arrests of presumed cardiac origin in whom resuscitation was attempted...

PURPOSE: Early and good quality cardiopulmonary resuscitation (CPR) and the use of automated external defibrillators (AEDs) are key factors to improve the outcome in patients with cardiac arrest. However, AED peri- and post-shock ECG analysis pauses may prolong hands-off time and reduce CPR effectiveness. METHODS: This study consisted of 2 independent parts. In the first part, the time performance of 12 different commercially available AEDs were tested in a manikin based scenario; in the second one, the AEDs recordings following the clinical use (same manufacturers as in the benchmark testing) in 2 different regions (Pavia, Italy, and Ticino, Switzerland) were retrieved and analyzed to evaluate the analysis time and post-shock time...

BACKGROUND: Available atrial electrograms in implantable cardioverter-defibrillators (ICD) improve arrhythmia diagnosis, allow monitoring for atrial fibrillation and may reduce the risk of inappropriate therapies. A recently introduced ICD system using a single-lead with floating atrial electrodes provides diagnostic capability of a dual-chamber system without placing an additional lead. Data on long-term clinical performance of this system are limited. METHODS: We retrospectively analyzed data from 35 consecutive patients implanted with Biotronik VR-T DX devices and Linox (Smart) DX leads...

OBJECTIVE: To assess the psychometric properties of the Patient Health Questionnaire (PHQ-9), a measure of depressive symptoms, in a large Danish national cohort of patients with heart disease, implanted with an implantable cardioverter defibrillator (ICD), using item response theory. METHODS: A prospective cohort of patients implanted with an ICD (n=1531; 80.4% men) completed the PHQ-9 at the time of implant. Data were analyzed using two item response theory models, the partial credit model and the generalized partial credit model...

INTRODUCTION: Sodium nitroprusside (SNP) enhanced CPR (SNPeCPR) demonstrates increased vital organ blood flow and survival in multiple porcine models. We developed a new, coronary occlusion/ischemia model of prolonged resuscitation, mimicking the majority of out-of-hospital cardiac arrests presenting with shockable rhythms. HYPOTHESIS: SNPeCPR will increase short term (4-hour) survival compared to standard 2015 Advanced Cardiac Life Support (ACLS) guidelines in an ischemic refractory ventricular fibrillation (VF), prolonged CPR model...

BACKGROUND: New advances in spinal cord stimulation have led to improved treatment of patients suffering from chronic pain. While the overall safety of newer stimulation devices has been established, no published reports exist regarding safety considerations when these devices are implanted in patients with a preexisting cardiac device. CASE REPORT: An 83-year-old man with a history of out-of-hospital cardiac arrest secondary to an episode of ventricular fibrillation underwent automated implantable cardiac defibrillator placement...

BACKGROUND: Correlation of increased copeptin levels with various cardiovascular diseases has been described. The clinical use of copeptin levels in patients with hypertrophic cardiomyopathy (HCM) has not been investigated before. HYPOTHESIS: In this study, we aimed to investigate the prognostic value of copeptin levels in patients with hypertrophic cardiomyopathy (HCM). METHODS: HCM was defined as presence of left ventricular wall thickness ≥15 mm in a subject without any concomitant disease that may cause left ventricular hypertrophy...

Implantable cardioverter defibrillator (ICD) is the cornerstone of primary and secondary prevention of sudden cardiac death. In 35 years of technologic improvement and clinical trials, there has been a continuous increase in implantation rate. Purpose of this review is to point out and discuss every aspect related to actual ICD management, investigating implantation procedure and predischarge care, office and remote monitoring follow-up, diagnostic evaluations, management of patients with suspected therapies or malfunctions, heart failure, surgery, radiotherapy and endoscopic procedures...

Celiac crisis, an atypical presentation of celiac disease, is characterized by acute diarrhea and severe metabolic derangements. This diagnosis is often missed in the differential of acute diarrheal illness. Our patient is a 69-year-old man who presented with ICD firing and was found to have profound metabolic derangements. Further evaluation revealed undiagnosed celiac disease and his symptoms resolved with a gluten-free diet. Celiac crisis should be considered in all patients presenting with acute diarrhea, metabolic acidosis, and severe electrolyte abnormalities as management can be life-saving...

The subcutaneous implantable cardioverter-defibrillator (S-ICD) is a safe alternative to transvenous ICD. We describe a submuscular S-ICD placement technique in a severely obese with an oversized chest. Submuscular configuration allows optimal system positioning and impendence values warranting a safe and effective shock transmission. This technique is safe and improves patients comfort.

Drug treatment and/or implantable cardioverter defibrillator (ICD) implantation are the most widely accepted first-line therapies for channelopathic patients who have recurrent syncope, sustained ventricular tachycardia (VT), or documented ventricular fibrillation (VF), or are survivors of cardiac arrest. In recent years, there have been significant advances in mapping techniques and ablation technology, coupled with better understanding of the mechanisms of ventricular tachyarrhythmia in channelopathies. Catheter ablation has provided important insights into the role of the Purkinje network and the right ventricular outflow tract in the initiation and perpetuation of VT/VF, and has evolved as a promising treatment modality for ventricular tachyarrhythmia even in channelopathies...

Medications such as ß-blockers are currently the primary treatment for patients with hereditary arrhythmia syndromes such as long QT syndrome (LQTS) and catecholaminergic polymorphic ventricular tachycardia (CPVT). However, these drugs are ineffective in some patients, and the other treatment option, that is implantable cardioverter defibrillator (ICD) implantation, is associated with significant complications in young and active patients. Left cardiac sympathetic denervation (LCSD) may reduce the wide gap between life-long ß-blocker medication and ICD implantation...

A 37-year-old man presented at our hospital. Pathological examination of a right orchiectomy specimen, radiographic examination, and tumor marker profile resulted in a diagnosis of retroperitoneal nonseminomatous germ cell tumor (intermediate risk according to IGCC classification). Laboratory testing revealed mild elevation of low density lipoprotein cholesterol. Induction chemotherapy with bleomycin, etoposide and cisplatin (BEP) was started, but he complained of chest pain on day 10 of the second cycle of BEP...

BACKGROUND: -A prolonged PR interval is common among cardiac resynchronization therapy (CRT) candidates; however, the association between PR interval and outcomes is unclear, and data are conflicting. METHODS: -We conducted inverse probability weighted (IPW) analyses of 26,451 CRT eligible (EF≤35, QRS≥120ms) patients from the National Cardiovascular Data Registry ICD Registry to assess the association between a prolonged PR interval (≥230ms), receipt of CRT with defibrillator (CRT-D) versus implantable cardioverter defibrillator (ICD), and outcomes...

Till recently, ST segment elevation in the absence of conduction abnormalities or chest pain occurring particularly in young bradycardia individuals has been considered a normal variant called early repolarisation (ER). However, recent studies suggest a more worrisome picture as patients with history of idiopathic ventricular fibrillation showed increased prevalence of ER in ECG. ER is an ECG pattern characterised by elevation of the QRS-ST junction (J point) ≥ 2 mv from baseline in the inferior (II, III, aVF) or lateral (I, aVL, V4-V6) leads manifested as QRS slurring or notching...
