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.

cardiologist salary and compensation data

Cardiologist compensation still rising, especially in invasive and interventional cardiology

Updated compensation data includes good news for multiple subspecialties. The new report also examines private equity's impact on employment models and how much male cardiologists earn compared to females.

AHA issues a scientific statement on COVID-19 cardiac arrhythmias

The objective of the AHA scientific statement is to review the available evidence on for better management of cardiac arrhythmias from COVID causes that are still encountered on a regular basis.

Cardiologists have performed what they believe to be the world’s first substernal lead extraction, sharing their experience in JACC: Case Reports.[1]The device being extracted, Medtronic’s Aurora EV-ICD, received U.S. Food and Drug Administration (FDA) approval in October 2023.

Cardiologists perform world’s first substernal lead extraction

The 49-year-old patient was not in pain or suffering any complications, but he wished to have his extravascular ICD removed once his symptoms improved. The care team agreed to extract it after a long discussion, and they said it was "easier than expected." 

The OmniaSecure defibrillation lead, which Medtronic describes as “the world's smallest transvenous defibrillation lead,” has a size of just 4.7 French.

Medtronic’s OmniaSecure, the smallest ICD lead of its kind, linked to long-term durability

Reliability modeling suggests the small-diameter defibrillation lead, already linked to positive early outcomes, should last patients for at least 10 years—and likely longer.

Rising heart failure, AFib rates a ‘wake-up call’ for US cardiologists

Today's heart teams already face a number of challenges on a day-to-day basis.  New data suggest they could soon be treating more patients than ever before.

With AFib ablation on the rise, HRS highlights importance of proper EP training

Cardiac ablation techniques and technologies are constantly evolving. Only well-trained specialists should be performing these procedures, the Heart Rhythm Society said in a new policy statement.

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.
