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.

Focal pulsed field ablation (PFA) is a safe, effective treatment option for premature ventricular contractions (PVC), according to new data published in Circulation: Arrhythmia and Electrophysiology.[1]

PFA ablation safe, effective for treating premature ventricular contractions

Early data suggest PVC ablation with PFA technology is associated with a high success rate and minimal complications.

Space travel disrupts normal rhythm in heart cells

Heart tissue samples that spent 30 days at the International Space Station appear to have been weakened by the low gravity conditions in space. This finding has implications for the heart health of astronauts.

Researchers have found that homemade play-putty can effectively capture electrocardiogram (ECG) signals at a level comparable to commercially available electrodes. The play-putty is made with a simple mix of flour, water, salt, cream of tartar and vegetable oil—but the potential is much more than one may expect.

Homemade electrodes made of putty capture heart data as well as some commercial devices

The putty, made with basic ingredients found around the house, can effectively capture ECG measurements.

LBBAP limits hospital readmissions after TAVR

Left bundle branch area pacing is associated with better long-term outcomes than traditional right ventricular pacing when patients require PPMI after TAVR, according to new research in Heart Rhythm

Boston Scientific has received U.S. Food and Drug Administration (FDA) approval for its INGEVITY+ pacing leads to be used for left bundle branch area pacing (LBBAP) when connected to a single- or dual-chamber pacemaker.

FDA approves Boston Scientific leads for left bundle branch area pacing

Boston Scientific's INGEVITY+ pacing leads were originally approved by the FDA back in 2019. They can now be used for LBBAP, a new alternative to biventricular pacing.

Two medical device companies have announced a transaction that could shake up the U.S. electrophysiology market. 

Harlan Krumholz, MD, SM, editor-in-chief of the Journal of the American College of Cardiology (JACC), and a cardiologist and the Harold H. Hines, Jr. Professor of Medicine at the Yale school Medicine, explains some of the key technology advances he is watching across cardiology.

JACC editor excited by progress during a 'very important moment' for cardiology

Harlan Krumholz, MD, editor-in-chief of the Journal of the American College of Cardiology, explains some of the key technology and treatment trends he has his eyes on.

Biotronik has received U.S. Food and Drug Administration (FDA) approval to make its Solia S lead and Selectra 3D catheter available for a new indication: left bundle branch area pacing (LBBAP).

LBBAP is a relatively new alternative to biventricular pacing. The FDA's decision was based largely on data from the BIO-CONDUCT clinical trial.
