Before catheter ablation or pacemaker implantation, all patients in both groups actually met the criteria for permanent pacing due to symptomatic prolonged sinus pauses on termination of AF (Fig. 2), ...

A doctor may recommend surgery for arrhythmia when medications and lifestyle changes haven’t been effective. The different types of arrhythmia surgeries each aim to restore a regular heart rhythm.

The first US safety and efficacy study of radiofrequency (RF) catheter ablation for vagal denervation in patients with neurocardiogenic syncope suggests the procedure can correct autonomic bradycardia ...

The efficacy of catheter ablation for heart failure (HF) patients with atrial fibrillation (Afib or AF) hinged on the phenotype of disease, researchers reported based on a meta-analysis. Compared with ...

Your heart has an internal pacemaker called the sinus node. It's a group of cells, located on top of your heart, that sends electrical signals into the heart and controls your heartbeat. Sometimes, ...

A pacemaker may be useful for atrial fibrillation (AFib) involving a slow heart rate or other heart conduction disorders. However, doctors may recommend lifestyle changes to manage AFib before a ...

Defibrillators use electrical shocks to restore a normal heart rate, especially in cases of life threatening arrhythmias or sudden cardiac arrest, while pacemakers use low-energy electrical pulses to ...
