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.

FDA clears AFib alerts for Samsung smartwatches

Samsung's smartwatches, already equipped with ECG technology, will now be able to alert users when signs of an irregular heart rhythm are detected. 

The Medtronic Micra leadless pacemaker implanted inside the heart. It is about the size of a large vitamin pill and is implanted using a catheter.

Medtronic’s next-generation leadless pacemakers gain FDA approval

The two new leadless pacemakers, the Micra AV2 and Micra VR2, feature much longer batteries than previous models. 

COVID-19 linked to elevated risk of life-threatening arrhythmia

Patients with severe COVID-19 cases that required ventilation were 16 times more likely to develop ventricular tachycardia within six months, researchers found.

Leadless pacemakers appear to be safe, effective in children with bradycardia

“Leadless pacemaker technology is the wave of the future,” one researcher said. “This is an excellent technology that may be offered to a wider pediatric population."

Images from the consensus document showing the proper left atrial appendage (LAA) sizing assessment for a transcatheter occluder device using transesophageal echo (TEE). Sizing and evaluation for pre-existing thrombus in the LAA also can be performed using cardiac CT.

SCAI and HRS release expert consensus on transcatheter left atrial appendage occlusion

One of the new recommendations is to conduct baseline imaging with TEE or cardiac CT.

Atul Verma explains thne results of the PULSE-AF trial at ACC23.

Pulsed-field ablation could be the next big EP technology trend

Atul Verma, MD, director of cardiology at McGill University Health Centre in Montreal, explained why the late-breaking PULSED-AF trial data on Medtronic’s pulsed-field ablation technology is so important for cardiologists.
