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.

GE Healthcare recall TruSignal SpO2 sensors

GE Healthcare recalls certain SpO2 sensors due to risk of serious errors during defibrillation

There is a risk of the devices sending a reduced amount of energy to the heart during defibrillation. More than 7,000 devices are being recalled due to this issue.

FDA approves Abbott’s Aveir dual chamber (DR) leadless pacemaker system, the world’s very first dual chamber leadless pacing solution for treating patients with abnormal heart rhythms.

FDA approves world’s first dual-chamber leadless pacemaker system

The minimally invasive system is made up of two pacemakers that send signals back and forth to one another. One pacemaker is placed on the patient's right ventricle, and the other is placed on the patient's right atrium.

Surgeons at NYU Langone Health successfully transplanted two genetically engineered pigs hearts into recently deceased humans in June and July.

Machine learning is playing a key role in predicting all major forms of drug cardiotoxicity, potentially helping reduce late-stage clinical trial failures.

Heart attack patients aged 65 and up stay hospitalized longer than those aged 65 or under—yet the seniors ring up significantly smaller bills per stay. The bad news is that the “savings” likely come in the form of fewer percutaneous coronary interventions (PCIs, aka angioplasties) to open blocked heart arteries nonsurgically.
