Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

People living with HIV face a heightened risk of sudden cardiac death

The risk was especially high in patients with high viral loads of HIV.

Monitoring high-risk patients for AFib fails to reduce stroke risk

"These findings might imply that not all AFib is worth screening for, and not all screen-detected AFib merits anticoagulation," researchers wrote. 

Amulet vs. Watchman: LAA occluder devices compared in new head-to-head trial

The Amulet's implantation success rate and LAA closure rate were both higher than the first-generation Watchman device, researchers reported.
