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.

FDA announces recall of cryoablation catheters after multiple injuries, including 4 deaths
Boston Scientific is recalling the catheters associated with its POLARx Cryoablation System due to a heightened risk of esophageal injury. The FDA has ruled that this a Class I recall.
Cardiologists perform world’s first leadless LBBAP procedures with Abbott pacemaker
The first-in-human procedures were performed in Prague with the investigational Aveir CSP leadless pacemaker system.
President of medical device company resigns over conduct allegations after 7 months in role
Joseph C. Wright, a longtime Merit Medical employee, resigned after unspecified allegations regarding his conduct were brought to light. He was named the company's new president back in May.
FDA and Boston Scientific issue urgent alert about pacemaker failures following 2 deaths
The U.S. Food and Drug Administration issued the recall notice for more than 200,000 pacemakers because a battery issue could lock the device in safe mode.
Treating AFib patients with TAVR still linked to elevated risks
While the technology and techniques associated with TAVR have advanced over the years, treating patients who present with baseline atrial fibrillation is still associated with certain risks.

FDA: Certain Medtronic pacemaker, CRT-P batteries can fail without warning

The FDA issued an alert May 7 warning patients with certain implanted Medtronic pacemakers or cardiac resynchronization therapy pacemakers (CRT-Ps) and their care teams to check for premature battery depletion in their devices after defects resulted in three reports and one patient death.
