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.

Cardiologists are first in world to use new cooling device to terminate AFib during surgery

Patients often develop AFib during cardiac surgery, leading to longer hospital stays, additional healthcare costs and a higher risk of mortality. Cooling the oblique sinus of the patient's heart as soon as AFib starts to develop may represent a new way to stop the problem in its tracks.

World’s first leadless LBBAP procedures linked to ‘promising’ outcomes

Cardiologists are turning to leadless pacemakers more and more for cardiac pacing, but those devices have not previously been able to perform LBBAP. This new analysis includes new data on the world’s very first leadless LBBAP procedures.

AI predicts LBBB risk in TAVR patients prior to treatment

The authors tested out a variety of machine learning techniques, including large language models and more traditional algorithms. They focused on data that can be gathered prior to treatment, ensuring cardiologists know as much as possible before the procedure.
