Contains fulltext : 190474.pdf (Publisher’s version ) (Open Access) Sudden cardiac arrest or death (SCA/SCD) in athletes has a low event rate. Pre-participation or eligibility screening is a widely accepted method of primary prevention of SCA/SCD in athletes. Most European countries and international sports governing bodies perform ECG-inclusive screening. However, implementation of a resting 12-lead ECG in pre-participation or eligibility cardiac screening is still a topic of debate. Recently, the 'International recommendations for electrocardiographic interpretation in athletes' was published in three leading international medical journals. These international ECG criteria are based on studies with detailed information on resting 12-lead ECG of Caucasian and Afro-Caribbean athletes or on consensus in case evidence was lacking. Normal, borderline and abnormal ECG findings in young athletes (age 12-35 years) are clearly described and illustrated to assist the screening physician in interpreting ECGs of athletes correctly.In this 'point of view paper' we will discuss whether these new ECG criteria actually help prevent SCA/SCD in athletes.

The Metrix™ Atrioverter Expanded Indication Trial evaluates the safety and efficacy of an implantable atrial defibrillator in patients with symptomatic, recurrent and drug refractory atrial fibrillation who also have structural heart disease. In this ongoing multicenter study, all patients are anticoagulated and concomitant antiarrhythmic drug treatment is left to the preference of the physician. Holter monitoring is performed prior to enrollment in the study. Spontaneous episodes of atrial fibrillation (AF) are treated under physician observation and when patients are ambulatory, the device is programmed in a monitoring mode. The atrial defibrillation threshold is measured at implantation and at 3, 6 and 12 months thereafter. The performance of the AF detection and R-wave synchronization algorithm is assessed at implantation, at regular follow-up intervals, and each time the patient visits the hospital for treatment of a spontaneous episode of AF. An echocardiogram is performed prior to implantation, at 3 and 6 month follow-up and for patients with an implanted heart valve, after 20 and 50 atrial defibrillation shocks have been delivered. The study started on October 1997 and will end after the last patient enrolled completes his/her six-month post-implantation follow-up, unless a safety issue arises. As of September 1998, 6 patients (2 patients with tachycardia induced cardiomyopathy, 1 patient with a mitral valve prosthesis, 2 patients with hypertrophic cardiomyopathy and 1 patient with congenital heart disease) have been enrolled in the study. Over 350 shocks have been delivered for atrial defibrillation testing or termination of spontaneous AF episodes. There have been no reported cases of ventricular proarrhythmia or inaccurately synchronized shocks and no complications of device therapy in this population.

This case report describes about a young, male patient with persisting syncope during physical therapy for complex regional pain syndrome type 1 after metatarsal fractures. The patient was referred to the Emergency Department, where Brugada syndrome was diagnosed. A cardioverter defibrillator was prophylactically implanted successfully. After this procedure, there were no contraindications for resuming further physical therapy for his painful foot. No clear causal inference with Brugada could be drawn from the complex regional pain syndrome type 1 or physical therapy described in this case report. Hyperthermia may, however, occur during such therapy, which is associated with dysrhythmia in general.
