The U.S. FDA has cleared the first clinical grade watch for characterizing atrial fibrillation (afib), the most common type of heart arrhythmia in which the heart beats too slowly or irregularly. Developed by Verily, the health tech arm of Alphabet Inc., together with IRhythm Technologies Inc., the Zio Watch will leverage the ability of IRhythm’s Zeus system to diagnose cardiac arrhythmias by combining wearable biosensing with cloud-based data analytics and artificial intelligence.

Timothy syndrome, a rare autosomal-dominant disorder, is characterized by presence of a heart arrhythmia (long QT syndrome), which causes the cardiac muscle to take longer than usual to recharge between beats and can result in sudden death. Now scientists at Columbia University have discovered that a common FDA-approved over-the counter cough suppressant, dextromethorphan, can shorten the prolonged QT intervals in both cellular and mouse models of TS.

PARIS – Teams from the Pitié-Salpêtrière hospital, the Institute for Research in Development, Sorbonne University and the National Institute of Health and Medical Research are proposing a new technique that uses artificial intelligence (AI) to identify the risk of developing a type of cardiac arrhythmia called Torsades de pointes (TdP) associated with taking certain drugs.

Robotic technologies company Stereotaxis Inc. is scaling up its footprint in the Chinese med-tech market, with a deal to commercialize its robotic technology for heart rhythm therapy in China with Shanghai Microport EP Medtech Co. Ltd. The St. Louis-based Stereotaxis aims to introduce a second-generation robot called Genesis to the Chinese market that uses a magnetic navigation technology to treat heart rhythm disorders. Its partner, Shanghai Microport EP Medtech, is a division of one of China's largest med-tech manufacturers, Shanghai-based Microport Scientific Corp.

Acutus Medical Inc. scored big with regulators in recent weeks. The company, which focuses on devices to diagnose and treat cardiac arrhythmias, received FDA approval to launch an investigational device exemption clinical trial for its Acqblate Force sensing ablation catheter and system in atrial fibrillation just two weeks after gaining CE mark approval for a broad suite of electrophysiology products.

Medtronic plc received U.S. FDA premarket approval of its Diamondtemp Ablation (DTA) system for treatment of patients with recurrent, symptomatic paroxysmal atrial fibrillation. The temperature-controlled radiofrequency (RF) ablation system features industrial-grade diamonds, which provide 200 to 400 times the thermal conductivity seen in conventional ablation and enable more efficient delivery of energy to regions of the heart responsible for the erratic electrical signals underlying atrial fibrillation (AF).

TORONTO – The 2-French Electrophysiology Catheter (2F) had its Canadian launch in mid-December at Toronto’s Sunnybrook Health Sciences Centre where electrophysiologist Benedict Glover used it to map the small, tortuous branches of the coronary sinus in a patient suffering from cardiac arrhythmia. Developed by Toronto-based Baylis Medical Inc., the 2F is expected to work in tandem with the company’s larger 6F catheter to help diagnose comparatively rare but complex heart arrhythmias.

San Carlos, Calif.-based Galaxy Medical Inc., which has developed pulsed electric field (PEF) technology for the treatment of cardiac arrhythmias, revealed the first treatments in the ECLIPSE-AF study, which is evaluating the Centauri system. The trial will assess the safety and efficacy of the Centauri as the company looks forward to obtaining a CE mark.

PARIS – Inheart SAS completed its first funding round of $4.2 million to improve cardiac arrhythmia treatment using medical imaging, artificial intelligence and digital simulation. This fund round was led by Elvia Partners SAS, a Parisian investment fund managed by Xavier Lazarus specializing in deep tech, and Aquitaine Science Transfer, a company accelerating technology transfer, from the University of Bordeaux.

BOGOTA, Colombia – Alivecor Inc., of Mountain View, Calif., is taking its Kardiamobile solution to capture medical-grade ECGs to the Mexican market after receiving clearance from the Comisión Federal para la Protección contra Riesgos Sanitarios, that country’s health care authority.
