Abstract
Detection of silent atrial fibrillation by pacemaker in patients with stroke or transient ischemic attack
Highlights
Atrial fibrillation (AF) is well-defined as a cardiac arrhythmia with the following features: superficial ECG displays ‘absolutely’ unequal RR intervals (AF is at times recognized as arrhythmia absoluta), i.e., RR intervals that do not follow a repetitive form; there are no different P waves on the superficial ECG
Follow-up was done during 18 months after the implantation procedure
Exclusion criteria were as follows: (i) ischemic heart disease; (ii) the left atrial volume higher than 69 mL in men and 54 mL in women; (iii) heart valvar disease that may lead to AF; and (iv) symptoms suggestive of AF
Summary
Atrial fibrillation (AF) is well-defined as a cardiac arrhythmia with the following features: superficial ECG displays ‘absolutely’ unequal RR intervals (AF is at times recognized as arrhythmia absoluta), i.e., RR intervals that do not follow a repetitive form; there are no different P waves on the superficial ECG. The present observational, prospective study was conducted at the Department of Cardiac Pacing and Cardiac Surgery of the Hospital e Clínica São Gonçalo. A cohort of patients received standard therapy for treatment of distal atrioventricular (AV) block and DDDR pacemaker implantation.
