Although medical students are rarely instructed in traffic medicine in Germany, they are obliged to inform their patients about their fitness to drive after having become a medical doctor. This article gives an overview on the fitness to drive for patients with syncope by referring to the driving license regulation and the current guidelines released by the department of traffic. The driving license regulation distinguishes between group 1 and group 2 drivers. Group 1 drivers drive vehicles with a total weight less than 3...

The subcutaneous implantable cardioverter-defibrillator (S-ICD®, Boston Scientific, Marlborough, MA, USA, previously Cameron Health, San Clemente, CA, USA) represents an important milestone in ICD therapy for prevention of sudden cardiac death (SCD). Since the introduction of the S‑ICD in 2010, the device has undergone further development. Based on the unique feature of an entirely extracardiac implantation, the S‑ICD is able to reduce the common perioperative and long-term complications of the usual endovascular implanted ICD systems...

Sudden cardiac death (SCD) in an apparently healthy individual is a tragedy. It is important to identify the cause of death and to prevent SCD in potentially at-risk family members. Inherited primary arrhythmia disorders are associated with exercise-related SCD. Despite the well-known benefits of exercise, exercise restriction has been a historical mainstay of therapy for these conditions. However, since familiarity with inherited arrhythmia conditions has increased and patients are often children and young adults, it is necessary to reassess the treatment guidelines regarding exercise constraints...

BACKGROUND AND PURPOSE: In acute stroke, hypertension worsens outcomes. Guidelines do not mention a preferred antihypertensive agent. This present study aimed to compare the efficacy and safety of nicardipine and clevidipine in acute stroke. METHODS: This retrospective review compared nicardipine with clevidipine for hypertension in acute stroke patients from March 17, 2015 to December 23, 2016. Ischemic and hemorrhagic stroke types were evaluated. Patients were excluded if under 18 years, had traumatic brain injury, had intracranial neoplasm, were on dialysis, had both study drugs during the stroke admission, or the study drug was infused for less than 1 hour...

Tachycardia is associated with cardiovascular mortality. Tachycardia is also a known clozapine adverse effect. However, whether clozapine-associated tachycardia is persistent is not known. Thirty clozapine-treated patients with clinical tachycardia were investigated with 24-hour ambulatory electrocardiography (ECG). Baseline peripheral heart rate (HR) was 106.7±7.8. The ambulatory ECG 24-hour-HR was 98.7±9.7. Baseline HR and 24-hour-HR correlated strongly (r=0.74, p=0.000003). Daytime HR was 106.4±9.9 and nighttime HR 89...

BACKGROUND: International guidelines recommend clinical assessment of the surviving first-degree relatives of sudden cardiac death (SCD) victims to identify a probable cause of death and protect surviving relatives. Only few studies have reported the outcome of clinical management and follow-up of relatives to SCD victims. METHODS: We performed a retrospective cohort study of the clinical and genetic assessment of surviving relatives of SCD victims referred to the Clinic of Inherited Cardiac Diseases at Aarhus University Hospital, Denmark, between 1995 and 2016...

Endocrine disorders are associated with various tachyarrhythmias, including atrial fibrillation (AF), ventricular tachycardia (VT), ventricular fibrillation (VF), and bradyarrhythmias. Along with underlying arrhythmia substrate, electrolyte disturbances, glucose, and hormone levels, accompanying endocrine disorders contribute to development of arrhythmia. Arrhythmias may be life-threatening, facilitate cardiogenic shock development and increase mortality. The knowledge on the incidence of tachy- and bradyarrhythmias, clinical and prognostic significance as well as their management is limited; it is represented in observational studies and mostly in case reports on management of challenging cases...

INTRODUCTION: Current AHA/ACC guidelines on the management of ST-elevation myocardial infarction (STEMI) suggest that an ECG is indicated within 10minutes of arrival for patients arriving to the Emergency Department (ED) with symptoms concerning for STEMI. In response, there has been a creep towards performing ECGs more frequently in triage. The objectives of this study were to quantify the number of triage ECGs performed at our institution, assess the proportion of ECGs performed within current hospital guidelines, and evaluate the rate of STEMI detection in triage ECGs...

Hypertension is not consistently associated with postoperative cardiovascular morbidity and is therefore not considered a major peri-operative risk factor. However, hypertension may predispose to peri-operative haemodynamic changes known to be associated with peri-operative morbidity and mortality, such as intra-operative hypotension and tachycardia. The objective of this study was to determine whether pre-operative hypertension was independently associated with haemodynamic changes known to be associated with adverse peri-operative outcomes...

PURPOSE OF REVIEW: Variant angina, which is characterized by recurrent chest pain and transient ECG changes along with angiographic evidence of coronary artery spasm, generally has a favorable prognosis. However, episodes of ischemia caused by vasospasm may lead to potentially life-threatening ventricular arrhythmias and cardiac arrest, even in patients with no history of prior cardiac disease. This review describes the epidemiology, pathogenesis, clinical spectrum, and management of variant angina, as well as outcomes in patients who present with aborted sudden cardiac death (ASCD)...

BACKGROUND: Hypertension is an important, modifiable risk factor for the development of atrial fibrillation (AF). Even after pulmonary vein isolation (PVI), 20-40% experience recurrent AF. Animal studies have shown that renal denervation (RDN) reduces AF inducibility. One clinical study with important limitations suggested that RDN additional to PVI could reduce recurrent AF. OBJECTIVE: The goal of this multicenter randomized controlled study is to investigate whether RDN added to PVI reduces AF recurrence...

In a 59-year-old woman with a perforating eyeball injury to the right eye, the emergency physician induced a preclinical general anesthesia with propofol, fentanyl and the depolarizing muscle relaxant succinylcholine. Anesthesia was maintained using propofol and remifentanil infusion throughout the preoperative period and the subsequent surgical procedure. Postoperatively, isolated rhabdomyolysis with an increase in serum creatine kinase to >20,000 U/l was observed. The diagnosis of malignant hyperthermia (MH) susceptibility could be confirmed in the patient 4 months after the acute event by the in vitro contracture test and detection of the MH causative mutation p...

Sudden cardiac death (SCD) accounts for ∼50% of mortality after myocardial infarction (MI). Most SCDs result from ventricular tachyarrhythmias, and the tachycardias that precipitate cardiac arrest result from multiple mechanisms. As a result, it is highly unlikely that any single test will identify all patients at risk for SCD. Current guidelines for use of implantable cardioverter-defibrillators (ICDs) to prevent SCD are based primarily on measurement of left ventricular ejection fraction (LVEF). Although reduced LVEF is associated with increased total cardiac mortality after MI, the focus of current guidelines on LVEF omits ∼50% of patients who die suddenly...

Idiopathic ventricular tachycardia: Frequent monomorphic premature ventricular contractions or non-sustained ventricular tachycardia without underlying structural heart disease is not a rare condition and may cause significant symptoms. A subgroup of patients develops IVT-associated cardiomyopathy. Current ESC guidelines recommend primary catheter ablation in symptomatic patients with right ventricular outflow tract IVT. Catheter ablation is also recommended in symptomatic patients with a left ventricular outflow tract (or other rare) origin, if antiarrhythmic drugs are ineffective or not desired...

INTRODUCTION: Although American Heart Association guidelines exist for proper management of cardiopulmonary arrest (CPA), in-hospital cardiopulmonary resuscitation (CPR) may be of poor quality and is not performed in all indicated situations. Cognitive aids have been created to assist in rapid, accurate recall of guidelines for pediatric CPA management. METHODS: Pediatric residents participated in individual mock codes for two years. Using a high-fidelity simulator, each resident participated in a standardized scenario that required management of both pulseless ventricular tachycardia and pulseless electrical activity...

BACKGROUND: In pregnant women with Graves' disease, maternal thyrotropin receptor antibodies (TRAb) can cross the placenta and induce fetal or neonatal thyrotoxicosis. Symptoms of fetal thyrotoxicosis are tachycardia, intrauterine growth restriction, and intra-uterine death. Recommendations on an upper limit of TRAb concentrations below which intensive fetal monitoring can be safely omitted vary between different guidelines. The objective of this study was to define an evidence-based cutoff level for maternal TRAb necessitating additional fetal monitoring during pregnancy...
