This condition may manifest as a heart rate that is too slow (bradycardia), too fast (tachycardia), or a combination of both (tachycardia-bradycardia syndrome). This device monitors the heart's rhythm and delivers electrical impulses via leads to ensure the heart continues to beat at a safe and effective rate.
Understanding SA Node Pacemaker Heart Rhythm Control
The sinoatrial node, often referred to as the heart's natural pacemaker, is a specialized cluster of cells located in the upper wall of the right atrium. The parasympathetic nervous system, primarily via the vagus nerve, acts to slow the heart rate during rest and digestion.
Symptoms can include dizziness, fatigue, shortness of breath, or fainting, necessitating medical evaluation and potential intervention. This impulse travels through the atria, causing them to contract and push blood into the ventricles.
SA Node Pacemaker Heart Rhythm Control and Function
When the natural pacemaker is significantly impaired, the standard treatment is the implantation of an artificial pacemaker. Symptoms can include dizziness, fatigue, shortness of breath, or fainting, necessitating medical evaluation and potential intervention.
