Occurrence and characteristics of stroke events in the Atrial Fibrillation Follow-up Investigation of Sinus Rhythm Management (AFFIRM) study. Minor variation in the P-P intervals may be present in most subjects, but the differences between the longest and shortest intervals usually do not exceed 0.12 s 1. The variation is attributed to changes in vagal tone as a result of reflex mechanisms arising from the pulmonary and systemic vascular systems during respiration 1. Epub 2004 Mar 8. 2. Some rhythms can be treated with a single-chamber pacemaker, which uses only one wire (lead) in the right atrium to pace the heart rate. Sinus node dysfunction: Treatment.

Its main characteristic on the EKG is a variation in the P-P intervals greater than 0.12 s with a normal P wave morphology 1 2. Respiratory sinus arrhythmia: Card Electrophysiol Rev. Clipboard, Search History, and several other advanced features are temporarily unavailable.

In atrioventricular (AV) node ablation, doctors use radiofrequency energy to destroy the electrical connection between the upper and lower heart chambers (AV node), blocking the heart's electrical impulses. The risk of complications, such as swelling or infection in the area where the pacemaker was implanted, is small.

AFFIRM and RACE trials: implications for the management of atrial fibrillation. W.B. The primary treatment goals are to reduce or eliminate symptoms and to manage and treat any other health conditions that may be contributing to sick sinus syndrome. The AFFIRM Study showed that treatment of patients with atrial fibrillation and a high risk for stroke or death with a rhythm-control strategy offered no survival advantage over a rate-control strategy in an intention-to-treat analysis.
