Optimal pacing mode for sick sinus syndrome.
To the Editor: I read with interest the article on the treatment of patients who have sick sinus syndrome (SSS) with single-chamber atrial pacing by Anderson et al.1 However, their finding of the annual risk of secondor third-degree atrioventricular (AV) block of only 0.6% per year contrasts somewhat with the reported findings that abnormal AV conduction was demonstrated in 57% to 67% of patien...
متن کاملA comparison of single-lead atrial pacing with dual-chamber pacing in sick sinus syndrome.
AIMS In patients with sick sinus syndrome, bradycardia can be treated with a single-lead pacemaker or a dual-chamber pacemaker. Previous trials have revealed that pacing modes preserving atrio-ventricular synchrony are superior to single-lead ventricular pacing, but it remains unclear if there is any difference between single-lead atrial pacing (AAIR) and dual-chamber pacing (DDDR). METHODS A...
متن کاملAtrial adaptive rate pacing in sick sinus syndrome: effects on exercise capacity and arrhythmias.
OBJECTIVE To test the hypotheses that adaptive rate atrial (AAIR) pacing: significantly increases maximal exercise capacity, and results in significant suppression of supraventricular and ventricular arrhythmia compared with fixed rate atrial (AAI) pacing. DESIGN Prospective, randomised, single blind, crossover study with maximal treadmill exercise testing and 24 hour ambulatory electrocardio...
متن کاملBenefits of dual chamber pacing in sick sinus syndrome.
The effects of DDD (fully automatic) and VVI (ventricular demand) pacing modes on exercise tolerance, symptom diary cards, and Holter monitoring were investigated in a randomised double blind crossover study of 16 patients who had had DDD pacemakers implanted because of frequent syncope. Eight patients presented with sick sinus syndrome and, with one exception, retrograde atrioventricular condu...
متن کاملPacing mode selection in patients with sick sinus syndrome.
INTRODUCTION SICK SINUS SYNDROME The sinus node is composed of a collection of specialised pacemaker cells embedded in a fibrous matrix that lies in the sulcus terminalis between the superior vena cava and the right atrial appendage. The sinus node serves as the primary cardiac pacemaker and controls the heart rate in normal individuals. Recent research indicates, that the sinus node is a heter...
