What causes Sick Sinus Syndrome?

Sick sinus syndrome is a condition in which the sinus node, which is the natural pacemaker of the heart, does not function normally. It is very rare in children and teenagers and is a complication of heart surgery involving the upper chambers of the heart (atria), where the sinus node is located.

What is sinus node disease?

sick sinus syndrome (sinus node disease) The sinus node normally produces 60-80 stimuli per minute. When its activity increases, it can alert up to 140-160/min. When the sinus node cannot fulfill its function, the disease of the node is mentioned. Sinus pause or sinus arrest sinus node is unable to stimulate.

What does Sinus Bradycardia mean?

Less than 60 impulses per minute from the sinus node is called sinus bradycardia. In cases where the sinus velocity is very slow, symptoms such as dizziness, weakness, and fatigue while walking occur. Fainting attacks are rare.

What is sinus node dysfunction?

Sinus node dysfunction (SND) is a group of abnormal heart rhythms (arrhythmias) usually caused by malfunction of the sinus node, the heart's primary pacemaker. Tachycardia-bradycardia syndrome is a variant of sick sinus syndrome in which arrhythmia alternates between fast and slow heart rates.

How many sinus node per minute?

Normally, 60-80 stimuli emerge from the sinus node at rest. This creates the heart rate.

What is sick sinus syndrome?

Sick sinus syndrome (HSS), sinus bradycardia due to sinus node degeneration, sinus pause, paroxysmal, regular or irregular atrial tachycardia, It is a syndrome characterized by various arrhythmias such as tachycardia-bradycardia attacks or atrial fibrillation with slow ventricular response.

What is a sinus node?

Sinoatrial node (SA node or sinus node) is the pacemaker tissue located in the right atrium of the heart. It provides the emergence of normal sinus rhythm. The sinoatrial node is a group of cells located in the right atrium wall, close to the entrance to the superior vena cava.
