Causes And Complications Linked To Sick Sinus Syndrome

Atrial Fibrillation

Atrial fibrillation is an irregular heart rhythm where the atria beat abnormally, chaotically, and out of coordination with the ventricles of the heart. This lack of coordination is a result of fast and erratic electrical signals being fired from the sinoatrial node. These impulses do not all successfully reach the atrioventricular node that connects the electrical pathway between the atria and ventricles. The result is the atria contracts and relaxes faster than the ventricles because of the difference in the frequency of electrical impulses between the two. Atrial fibrillation can cause an individual to develop heart failure or have a stroke. It is a common complication seen in sick sinus syndrome patient. The reason for this is because the dysfunction that causes atrial fibrillation lies within the firing of electrical impulses by the sinoatrial node, which should fire impulses at a steady and even rate so the chambers of the heart will contract and relax at the proper times. The aberrant and rapid impulses that result in atrial fibrillation can occur due to sick sinus syndrome.
