At rest, a healthy sinus node produces electrical impulses for a heart rate of between 60 and 100 beats per minute. This is anormal sinus rhythmor normal heart rhythm.1 Sick sinus syndrome occurs when damage or disease to the sinus node causessinusarrhythmia(irregular sinus signals) that is ...
Sick Sinus Syndrome comes in three flavors, all with different causes: • Sinoatrial block: Slower than normal heart beat caused by electrical signals that slow down when passing through the sinus node. • Sinus arrest: To go back to the musical analogy, think of a “rest” (a musical ...
Sick sinus syndromeis due to defective sinus nodes. The sinus nodes are the natural pacemakers in the heart. Heart rhythms will beat too quickly or, more commonly, too slowly when malfunctioning. Conduction blockis a heart rhythm condition caused by a breakdown in the flow of the electrical pu...
The conduction system, also called the cardiac electrical system, helps the heart contract, thus pumping blood through the body. It is made up of several different parts, including a sinoatrial (sinus) node. The sinus node is a small collection of tissue. It can be found in the heart's ...
Heart rate vs. pulse rate While the two go hand in hand, they are different. Your heart rate is a measure of the number of times yourheart beatsin a minute. With each beat, your heart squeezes. That creates enough pressure to push blood out of your heart to the rest of your body ...
Kartagener syndrome is also known as primary ciliary dyskinesia. This is a genetic disorder. Cilia on the surface of cells are not functioning properly. It affects cells in respiratory tract and fallopian tubes. In this way, mucus cannot be eliminated properly. This can lead to many respiratory...

In this case, a 57-year-old man was admitted for outpatient cardiological evaluation of progressive right heart failure and limb paraesthesias. The patient presented with hypertension, chronic Guillain-Barre syndrome, and sick sinus syndrome. Transthoracic echocardiograms showed a thickened ventricular...
Blood tests may be done to see if you have any heart damage. They may also be used to find the cause of your bradycardia. Echocardiography is a type of ultrasound. Sound waves are used to create pictures of your heart as it beats. An ECG records the electrical activity of your heart....
