Tachy Brady syndrome, also known as Sick Sinus syndrome or sinus node dysfunction, is a medical condition affecting the human heart, not the nasal sinuses as some may misinterpret. While the name is a bit misleading to non-medical professionals, the causes and symptoms of the condition are more straightforward. Tachy Brady sydrome is a rare condition, but it is one that can lead to additional risk if left untreated. What should you know about Tachy Brady syndrome?
What is Tachy Brady Syndrome? Sick Sinus syndrome occurs when the sinus node of the heart fails to function properly. The sinus node is considered the heart’s biological pacemaker as it sets the heart rate rhythm. When the sinus node is dysfunctional, a number of irregular heart rhythms may occur, from rapid heart rates, pauses or skips in the heart beat, slow heart rates or a combination of fast and slow heart rhythms.
What Causes Tachy Brady Syndrome? The condition is often caused by age. As an individual ages, the sinus node ages and wears or scars as well. In other cases, the defect may be genetic or occur at birth. Additionally, certain medications such as beta-blockers may worsen slowed heart rhythms presented in Tachy Brady syndrome as they typically lower heart rate.
What are the Symptoms of Tachy Brady Syndrome? Patients suffer from rapid heart rates, called tachycardia. Alternately, those same patients will have periods of slower than normal heart rates called brachycardia and sometimes periods of abnormal rhythm pauses or skipped heart beats. These abnormalities in heart rhythm affect the body’s ability to successfully pump blood and circulate oxygen and nutrients throughout the body. The abnormal heart rhythm sometimes leads to chest pain, heart palpitations, dizziness, difficulty breathing or even fainting.
What is the Treatment of Tachy Brady Syndrome? Both the rapid and slow heart rhythms must be regulated. Unfortunately most medications act to either increase or lower heart rate, making it difficult to regulate this combination rhythm disorder with prescription medications. Many times an artificial pacemaker is required to perform the heart rhythm pacing of the dysfunctional sinus node.
What are the Risks of Untreated Tachy Brady Syndrome? Many patients suffering from Sick Sinus syndrome are often also at risk for other heart and cardiovascular disorders, including stroke. Patients are also at a greater risk of injuries during falls from fainting episodes.
