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. This condition may manifest as a heart rate that is too slow (bradycardia), too fast (tachycardia), or a combination of both (tachycardia-bradycardia syndrome).
Evolutionary Principles Governing the Cardiac Physiology of the SA Node Pacemaker
This impulse travels through the atria, causing them to contract and push blood into the ventricles. Diagnostic and Therapeutic Approaches Diagnosis of SA node dysfunction typically involves monitoring the heart's electrical activity through an electrocardiogram (ECG) or Holter monitor.
Understanding these variations provides valuable insights into the fundamental principles of cardiac physiology and evolution. The parasympathetic nervous system, primarily via the vagus nerve, acts to slow the heart rate during rest and digestion.
Evolutionary Principles Governing the Cardiac Physiology of the SA Node Pacemaker
This condition may manifest as a heart rate that is too slow (bradycardia), too fast (tachycardia), or a combination of both (tachycardia-bradycardia syndrome). When the natural pacemaker is significantly impaired, the standard treatment is the implantation of an artificial pacemaker.
