The driving impulse of the heart ordinarily arises in the P cells of the sinoatrial node. Pace-making foci are not, however, limited to the sinus node; others exist outside of it in the atrial myocardium. This observation has lead some electrocardiographers to speak of the atrial pace-making complex, a term that includes foci both within and outside of

Underdrive Suppression of the Sinus Rhythm in Man
Chest, 1985This report demonstrates unusual responses of the sinus rhythm to atrial pacing. The sinus rhythm failed to become manifest when the heart was driven at a rate slower than the inherent sinus rate. Sinus rhythm returned only after termination of underdrive pacing with the recovery time longer than twice the cycle length of the control sinus rhythm.

Further studies on coronary sinus rhythm∗
The American Journal of Cardiology, 1958Abstract 1. (1) Certain characteristics of coronary sinus rhythm are discussed. 2. (2) Three main forms of this arrhythmia are recognized. 3. (3) It is shown on clinical observation that the differentiation of these three forms and therefore the evaluation of each case may meet with great difficulties in practice.

Anticoagulation for heart failure in sinus rhythm
2000Patients with chronic heart failure (heart failure) are at risk of thromboembolic events, including stroke, pulmonary embolism and peripheral arterial embolism, whilst coronary ischaemic events also contribute to the progression of heart failure. Long-term oral anticoagulation is established in certain groups, including patients with heart failure and ...

Does Sinus Rhythm Beget Sinus Rhythm?
Pacing and Clinical Electrophysiology, 2004The aim of this study was to determine the effect of early patient activated cardioversion of atrial fibrillation (AF) using the atrial defibrillator on recurrence of AF. Fifteen patients, mean age 63 ± 14 years, 80% men, with drug‐resistant persistent AF were implanted with the Jewel AF atrial defibrillator.

Superior Vena Cava Rhythm Masquerading as Normal Sinus Rhythm
Journal of Cardiovascular Electrophysiology, 2004We report the case of a patient with persistent cardiac rhythm originating from the superior vena cava (3 cm above the vena cava‐atrial junction). It was detected by noncontact balloon mapping before induction of tachycardia and confirmed by conventional contact mapping with image studies.

Morphology of the region of the coronary sinus in respect to coronary sinus rhythm
International Journal of Cardiology, 1990The arterial supply to the region of the coronary sinus and the interatrial septum was examined in 18 normal canine hearts. In 13 of a further 18 dogs, coronary sinus rhythm was evoked by the ligation of atrial arteries, subsequent to which the arteries were visualized by injection of latex.

Azimilide dihydrochloride (azimilide) is an investigational antiarrhythmic drug that has been tested in patients with a variety of arrhythmias. In patients with atrial fibrillation, it has shown excellent efficacy in some previous trials and minimal efficacy in others.Patients who had symptomatic atrial fibrillation for > 48 hours but < 6 months were ...

Pulmonary Vein Isolation and Sinus Rhythm
Revista Española de Cardiología (English Edition), 2009and the patient converted to sinus rhythm, as is seen in the CS electrograms (Figure 2). The PV maintained a fibrillatory rhythm that later regulated to atrial tachycardia, and ultimately disappeared spontaneously (Figure 3). Pulmonary vein ablation is currently the treatment of choice for paroxysmal AF resistant to medical treatment.

Sinus rhythm with isolated pulmonary vein fibrillation
Heart, 2010A 47-year-old man was referred for pulmonary vein isolation for paroxysmal atrial fibrillation. During catheter ablation to encircle the left superior pulmonary vein, application of radiofrequency energy was applied to the roof of the vein restoring sinus …
