Electrocardiography remains one of the most accessible tools for detecting cardiac rhythm disorders. A standard 12-lead ECG can reveal atrial fibrillation,…

Cardiac implantable electronic devices (CIEDs), including pacemakers, implantable cardioverter-defibrillators, cardiac resynchronization systems, and loop…

Vasovagal syncope is usually benign in mechanism but can be profoundly disruptive in practice. Recurrent fainting may cause traumatic injury, driving…

Cardiac amyloidosis changes the structure and electrical behavior of the heart at the same time. Amyloid deposits can thicken the ventricular walls, impair…

Catheter ablation for atrial fibrillation has become a highly effective rhythm-control treatment, yet the procedure carries a clinically important risk of…

Abandoned transvenous leads are increasingly encountered in patients with long-standing cardiac implantable electronic devices. A lead may be left in place…

Atrial fibrillation and chronic kidney disease frequently occur together, creating a difficult balance between embolic protection and bleeding prevention.…

Ventricular tachycardia (VT) in nonischemic cardiomyopathy presents a distinctly difficult ablation problem. Unlike post-infarction VT, where the…

Syncope is a transient loss of consciousness caused by temporary global cerebral hypoperfusion, followed by spontaneous recovery. Although many episodes are…

Atrial fibrillation (AF) ablation has evolved from a procedure centered on point-by-point lesion delivery to one supported by sophisticated mapping, contact…
