Insights

Slow pathway ablation effectively treats slow-fast atrioventricular nodal reentrant tachycardia (AVNRT). A complex signal identification map precisely located the ablation target near the coronary sinus ostium for successful treatment.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Devices

Background:

  • Slow pathway (SP) ablation is a standard treatment for slow-fast atrioventricular nodal reentrant tachycardia (AVNRT).
  • High success rates and low recurrence characterize established SP ablation therapies.
Keywords:

Dysrhythmias II: Classification of Tachyarrhythmias

Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...

Electrophysiology of Normal Cardiac Rhythm01:19

Electrophysiology of Normal Cardiac Rhythm

The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase...
