Studies on the Mechanism of Sinus Node Dysfunction in the Sick Sinus Syndrome JAY

چکیده
The intrinsic heart rate (IHR) was determined in 17 patients with symptomatic sinus bradycardia by administering atropine 0.04 mg/kg and propranolol 0.2 mg/kg, i.v. In this way, sick sinus (SSS) patients with intrinsic sinus node (SN) dysfunction could be distinguished from those patients with disturbed autonomic regulation of SN function. Sick sinus syndrome patients with normal corrected sinus node recovery time (SNRTC), adjusted for the magnitude and direction of autonomic chronotrophy, consistently had

Familial sinoatrial node dysfunction. Increased vagal tone a possible aetiology.
Clinical and electrophysiological studies of a 13-year-old boy with sinus bradycardia revealed sinus node dysfunction. Long-term follow-up data of members of his family indicated familial sinus node dysfucntion. Increased vagal tone was present in all patients. It is suggested that excessive vagal discharge for a pronlonged time may be the basic mechanism of sinus node dysfunction in these pati...

node as the region responsible for activation of the heart.1 Laslett first suggested sinus node dysfunction as a cause of bradycardia in 1909, and during the 1950s and 1960s Short, Ferrer, Lown, and others described the clinical spectrum of sinus node dysfunction that is commonly called the “sick sinus syndrome resting sinus bradycardia.”2-5 Sinus node dysfunction can have multiple electrocardi...

Digoxin, in a common clinical dose and at a low serum level, brought out severe manifestations of sinus node dysfunction in a patient who had previously undergone successful mitral valve replacement. This report presents the results of extensive clinical and electrophysiologic studies of this patient before and after a digoxin challenge. In the absence of cardiac glycoside, the only demonstrabl...

A family with sick sinus syndrome is presented: a mother and her 2 daughters affected with sinus node dysfunction. Electrophysiological studies revealed abnormal atrioventricular conduction in the 2 daughters. All 3 individuals were implanted with a permanent pacemaker to relieve their symptoms. Endomyocardial biopsy from the right ventricle of one daughter showed disarrangement, degeneration, ...

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...
