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.

AI model for HCM, the first of its kind, gains FDA approval

The new-look AI model was designed to automatically evaluate ECGs for signs of HCM and send alerts to the care team when necessary. 

FDA highlights importance of including heart rhythm risks on drug labels

The agency has shared a new draft guidance focused on the inclusion of information related to QTc interval prolongation.

Relaxed fasting instructions prior to TAVR, other heart procedures do not affect outcomes

Fasting before major operations has been common in healthcare for nearly 80 years, but that has started to change since the turn of the century. 

Boston Scientific’s POLARx Cryoablation System for atrial fibrillation gained FDA approval in August 2023.

FDA approves Boston Scientific’s new cryoablation system for AFib

The system includes an expandable cryoablation balloon catheter compatible with multiple balloon sizes.

NFL player feeling thankful after AFib diagnosis: ‘I think it’s just the good Lord looking after me’

Tyler Shatley, a veteran offensive lineman with the Jacksonville Jaguars, said he experienced symptoms for years before finally seeking a diagnosis. 

The ThermoCool SmartTouch SF catheter from Biosense Webster

FDA approves several Biosense Webster devices for fluoroscopy-free ablation procedures

Using these devices as part of a zero-fluoroscopy workflow, which replaces X-rays with an alternative modality such as ultrasound, limits radiation exposure and the use of burdensome protective equipment.

New research, based on data from approximately 143 million patients, focused on prescriptions for heart failure, atrial fibrillation and other significant cardiac conditions. 

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.
