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 clears AI software for heart murmur detection with digital stethoscopes
eMurmer's new Heart AI software was designed to detect both the presence and absence of heart murmurs in digital stethoscope recordings. It can also gather critical hemodynamic data, helping care teams gain a better understanding of the patient's cardiovascular health.
Medtronic’s newest all-in-one PFA catheter gains critical approval
The all-in-one mapping and single-shot PFA catheter was developed with electrophysiologist feedback in mind.
Abbott’s medtech sales climbed in Q4 thanks to strength of heart devices
Abbott pointed to double-digit growth for its Navitor TAVR valve as well as big gains for the TriClip and MitraClip devices. The company also shared positive sales figures for its EP, heart failure and rhythm management portfolios.
FDA-approved PFA system linked to positive 1-year data, ‘impeccable’ durability
The Globe Pulsed Field System, which secured FDA approval in September 2025, features high-density mapping capabilities and a 122-electrode spherical array.
Abbott works with AtaCor Medical on extravascular ICD system
Extravascular ICDs were developed to avoid complications such as vascular injuries, lead fractures and lead infections. Although rare, these issues can cause serious, life-threatening complications for patients.
