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.

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
