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.

Left bundle branch block after TAVR hurts outcomes, even when no permanent pacemaker is required

Researchers tracked data from more than 2,000 TAVR patients, focusing on cardiovascular mortality and hospitalizations for heart failure.

Regulatory roundup: FDA clears new solutions from Boston Scientific, CathVision, Franklin Mountain Medical

It has been a busy few weeks for the FDA, with plenty of big-name approvals and recalls making the news, but there have also been some other big announcements related to solutions receiving FDA clearance.

Real-world Watchman patients experiencing fewer complications after LAAO than seen in clinical trials

The study's authors compared findings from the PROTECT-AF and PREVAIL clinical trials with data from the NCDR LAAO Registry, focusing on short-term and long-term outcomes.

Brugada arrhythmogenic substrate that causes VT and sudden cardiac death. This study showed ablation of this substrate area could help prevent sudden cardiac arrest in these patients.

Epicardial ablation in Brugada syndrome reduces sudden cardiac death

A late-breaking study at Heart Rhythm 2022 found epicardial ablation in Brugada syndrome helped significantly reduce sudden cardiac arrest in these patients, increasing their survival.

Veteran cardiologist Morton M. Mower, co-inventor of the automatic ICD, dies at 89

“I think he was the most brilliant person I’ve ever met," one long-time colleague said.

Same-day discharge for AFib ablation a success thanks to telehealth

The new analysis, presented during Heart Rhythm 2022, focused on patients treated at a high-volume facility during the COVID-19 pandemic.

FDA approves mavacamten for obstructive hypertrophic cardiomyopathy

The FDA’s approval was based on data from the EXPLORER-HCM trial, which showed that mavacamten was superior to a placebo for treating obstructive HCM and associated with no significant long-term, treatment-related adverse events.

VIDEO: How to implant a Linq implantable cardiac monitor

The Medtronic Linq and Linq II implantable cardiac monitors (ICM) have become some of the most popular ICM devices on the market, partly because they are easy to insert.
