Permanent Pacing Treatment: Conventional DDDR, Antitachycardia Pacing or Atrial Defibrillator?

摘要

Atrial fibrillation is the most common arrhythmia in clinical practice and its incidence is increasing due to the aging of the population. It is associated with major clinical complications, such as heart failure, acute myocardial infarction, and stroke, and with impaired quality of life [1,2]. Antiarrhythmic drugs have been widely used for cardioversion and maintenance of sinus rhythm, but they showed limited and usually temporary efficacy [3]. In consequence, several nonpharmacological therapies including physiological pacing, pacing prevention algorithms, antitachy pacing therapies, and low-energy internal cardioversion have been introduced to treat drug-refractory arrhythmias [4-6], and have been implemented in multifunction implantable devices.
