Electrophysiology

The cardiac subspecialty of electrophysiology (EP) diagnoses and treats arrhythmias. This includes use of pacemakers to treat bradycardia, implantable cardioverter defibrillators (ICD) for tachycardia, heart failure and patients at risk of sudden cardiac arrest, and cardiac ablation treatments to treat heart rhythm disorders.

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.

Can intracardiac echo replace TEE during structural heart procedures?

TEE has been used to guide most transcatheter structural heart cases over the past decade, but 3D ICE is changing how some centers image those patients.

Researchers design new material for wearable devices: ‘You cannot feel it, and you will likely forget about it’

The soft, stretchable material creates so little pressure that users will likely not even even be able to feel it.

AI model predicts risk of post-operative AFib

Post-operative atrial fibrillation was once viewed as a fairly insignificant issue, but more recent research suggests it can increase a patient’s risk of multiple adverse events.

Abbott gains new FDA approval for one catheter, CE mark approval for a second catheter

Both devices were approved for treating significant heart rhythm issues.

Peter Libby, MD, a cardiovascular medicine specialist with Brigham and Women’s Hospital, discussed the cases of AFib being seen in long-COVID patients.

Severe gum infections linked to heightened AFib risk

Researchers are still working to determine if gum disease leads to heart rhythm issues or if is actually the other way around.

$Extracorporeal CPR refractory out-of-hospital cardiac arrest$

Extracorporeal CPR for out-of-hospital cardiac arrest: New research fails to provide answers

While a previous study had found that extracorporeal CPR outperformed conventional CPR among patients with out-of-hospital cardiac arrest, a newer analysis suggests the two treatment options result in similar outcomes.

Infection, heart failure the most common reasons for early mortality after transvenous lead removal

Early mortality specifically related to complications during the TLR procedure was quite rare.
