The Year in Cardiology 2013: arrhythmias.

The Year in Cardiology 'arrhythmias' presents an update on the latest studies and innovations published in the field within the last 12 months. Recent advances in the management of atrial fibrillation and novel treatment strategies and technologies are presented. New consensus documents to improve the diagnosis and treatment of patients with inherited cardiac arrhythmias and for paediatric patients with cardiac arrhythmias are summarized. Great progress has also been made in the field of cardiac implantable electronic devices: improvements in implantation techniques and novel technologies have been introduced and successfully applied. In addition, novel data on prevention of implantable cardioverter defibrillator-shocks and cardiac resynchronization therapy will certainly help to improve the quality of care for patients with cardiac arrhythmias and heart failure.
