Below is the initial ECG rhythm strip in lead II. Sinus arrest with atrial (beats 2,4,6) and junctional escape beats (1,3,5) The conduction system is designed so that if the sinoatrial (SA) node fails, an escape rhythm from a lower pacemaker site occurs.

van Dusen KTR, Mednick SA The ECG Made Practical. John Hampton 8 Sinus Node Dysfunction. 9 Atrioventricular 14 Atrial Tachyarrhythmias in Congenital Heart Disease. 15 Atrial AV indicates atrioventricular; AVNRT, atrioventricular nodal reentrant tachycardia; in patients without structural heart disease or ischemic heart disease who have who do not have pre-excitation on their resting ECG during sinus rhythm.

Although the sinus node depolarises normally, there is intermittent failure of that impulse being conducted through the atrial tissue. When the sinus node generates an electrical impulse, the surrounding cells of the right atrium depolarize. Then the cells of the left atrium, the AV (atrioventricular)node, follow, and at last the ventricles are stimulated via the His bundle. With this knowledge it is quite simple to recognize normal sinus rhythm on the ECG. Sinus Node Dysfunction Refers to problems with sinus node impulse formation and propagation May include sinus bradycarda, sinus pauses or arrest, chronotropic incompetence, and sino-atrial exit block When accompanied by symptoms it is referred to as Sick Sinus Syndrome The diagnosis of sinus node dysfunction (SND) in patients with suggestive symptoms is often made on the basis of surface electrocardiographic (ECG) features. Manifestations seen on ECG may include Sick sinus syndrome — also known as sinus node disease or sinus node dysfunction — is the name for a group of heart rhythm problems (arrhythmias) in which the sinus node — the heart’s natural pacemaker — doesn’t work properly. SSS is a dysfunction of the SA node due to age, causing sluggish or absent pacemaking impulses. Symptoms are fatigue, lightheadedness, palpitations, and syncope.

Sinus node dysfunction is commonly encountered in clinical practice. The clinical presentation can range from asymptomatic bradycardia to atrial standstill with a wide variety of symptoms (many of which are vague and intermittent). SND is commonly seen in older adults and is …

A slow, irregular pulse suggests the diagnosis of sinus node dysfunction, which is confirmed by ECG, rhythm strip, or continuous 24-hour ECG recording. Some patients present with atrial fibrillation (AF), and the underlying sinus node dysfunction manifests only after conversion to sinus rhythm.

SA node dysfunction may be difficult to distinguish from physiologic sinus bradycardia, particularly in the young. SA node dysfunction increases in frequency between the fifth and sixth decades of life and should be considered in patients with fatigue, exercise intolerance, or syncope and sinus bradycardia.

Sinus pause or arrest. Sinoatrial (SA) exit block. Sinus node dysfunction affects mainly older patients, especially those with another cardiac disorder or diabetes. Sinus pause is temporary cessation of sinus node activity, seen on electrocardiography (ECG) as disappearance of P waves for seconds to minutes.

SA Dysfunction is a sign of diseased tissue around the sino-atrial node. This may be damage secondary to an MI , or to a degenerative ageing process affecting the node. Although the sinus node depolarises normally, there is intermittent failure of that impulse being conducted through the atrial tissue.

Sinus pause is temporary cessation of sinus node activity, seen on electrocardiography (ECG) as disappearance of P waves for seconds to minutes. Sinus pause or arrest.
