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.

P‐waves can help identify Black patients prone to developing AFib
Research that followed patients for more than 13 years suggests increases in ECG PR interval, P‐wave duration and PTFV1 are associated with increased AFib risk in this cohort.
New-onset AFib is common after CABG—but typically not persistent or symptomatic
The study's authors questioned if these patients should even be given oral anticoagulation as currently recommended.
Field Medical’s PFA system for ventricular tachycardia shows early potential
More research is still required, but Field Medical's FieldForce Ablation System may represent a significant step forward in the treatment of scar-related ventricular tachycardia.
Medtech companies working together on robotic PFA system
Stereotaxis and CardioFocus are collaborating on a new robotic pulsed field ablation system. After completing some initial research, the companies are now working toward the launch of a clinical trial.
Q&A: What cardiologists know and don’t know about pulsed field ablation
Peter Weiss, MD, a veteran electrophysiologist, sat down with Cardiovascular Business to discuss the ongoing rise of pulsed field ablation. While he's impressed with the technology, he says many questions remain about its long-term value.

FDA details Class I recalls for more than 1 million pacemakers—software update required

The FDA has finalized new Class I recalls related to ongoing safety concerns with Boston Scientific’s Accolade family of pacemakers. A software update is now available to help address the issue, and an additional update is already in the works.

The U.S. Food and Drug Administration (FDA) granted pre-market approval (PMA) clearance for Zoll Zenix defibrillator-monitor for EMS and hospital use. It incorporates new technology and features based on years of user feedback.
