![]() An echocardiogram is a type of ultrasonic imaging of the heart.An electrocardiogram (ECG or EKG) is a test that records the electrical activity of the heart at that precise moment.If there are not any symptoms at the time of the ECG, it may appear normal. ![]() To be certain, an electrocardiogram (ECG) will be conducted to record the heart’s rate and rhythm. The physician or cardiologist may suspect this condition based on the symptoms, however, these symptoms are common in many other diseases. A clogged coronary artery limits blood flow to the heart.History of congenital heart disease (even with repairs, the heart is still weak).Congenital heart defects are the leading cause in both children and adults. Congenital sick sinus syndrome refers to having the disease at birth. Sick Sinus Syndrome Risk FactorsĪs individuals advance in age, they become more susceptible to developing sick sinus syndrome. These symptoms are associated with reduced cardiac output from bradyarrhythmias or tachyarrhythmias, which can lead to decreased cerebral perfusion and cause syncope or pre-syncope. Patients dealing with sinus syndrome may be asymptomatic or have mild and non-specific symptoms. Medications to treat high blood pressure or arrhythmias.Damage to the sinus node or scarring due to any heart surgery.Age-related wear and tear of heart tissues.Tachycardia-bradycardia (or tachy-brady) syndrome: This is when the heart alternates between very slow and very fast beats.Īny condition that can lead to cardiac damage can affect the SA node as well.Sinoatrial block: The sinus node impulse is prevented from reaching the atria, the two upper chambers of the heart.Sinus arrest or sinus pause: The sinus node temporarily stops working or pauses, causing a change in the heart’s beating.Sinus bradycardia: The heart beats very slowly which is less than 60 beats per minute.Sinus sick syndrome is defined by the following disorders: The resulting heartbeat or rhythm will differ depending on the specific electrical activity at the sinus node. When the sinus node fails to function properly, a variety of disorders develop. While it is relatively uncommon, the risk of developing the syndrome increases with age.īradycardia-tachycardia syndrome, sinus node dysfunction, slow heart rate – sick sinus, tachy-brady syndrome, sinus pause – sick sinus, and sinus arrest – sick sinus are all alternative names for this syndrome. ![]() This can lead to heartbeats that are either too slow, too fast or that switch between slow and fast. This may be a consequence of other medical issues that gradually damage the sinoatrial node (SA node) or from particular medications. Sick Sinus Syndrome (SSS) is a condition in which the heart’s natural pacemaker, located in the right atrium, is impaired and is unable to generate regular electrical signals. These signals travel through the atria and into the ventricles, prompting them to contract and pump blood to the lungs and body. The sinus node, which is found in the right atrium, is the natural pacemaker and produces electrical signals to control the heart rate. The heart is composed of four chambers – two atria located at the upper portion and two ventricles located at the lower portion. Understanding what is Sick Sinus Syndrome The mainstay of treatment is to provide adequate symptom relief while decreasing the incidence of atrial fibrillation, thromboembolic events, heart failure, and mortality. Sick sinus syndrome is challenging to diagnose due to its nonspecific symptoms and enigmatic electrocardiogram findings. ![]() It is frequently asymptomatic or has nonspecific or subtle symptoms. While there are many possible causes, it is usually idiopathic. The arrhythmias associated with this syndrome, typically involve persistent bradycardia with intermittent tachyarrhythmias. Sick sinus syndrome also known as sinus node dysfunction-is a term used to describe a number of different abnormalities in the heart rhythm (known as arrhythmias). ![]()
