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.

Cardiologists are first in world to use new cooling device to terminate AFib during surgery
Patients often develop AFib during cardiac surgery, leading to longer hospital stays, additional healthcare costs and a higher risk of mortality. Cooling the oblique sinus of the patient's heart as soon as AFib starts to develop may represent a new way to stop the problem in its tracks.
World’s first leadless LBBAP procedures linked to ‘promising’ outcomes
Cardiologists are turning to leadless pacemakers more and more for cardiac pacing, but those devices have not previously been able to perform LBBAP. This new analysis includes new data on the world’s very first leadless LBBAP procedures.
AI predicts LBBB risk in TAVR patients prior to treatment
The authors tested out a variety of machine learning techniques, including large language models and more traditional algorithms. They focused on data that can be gathered prior to treatment, ensuring cardiologists know as much as possible before the procedure.
Consistent cannabis use linked to multiple cardiovascular risks for heart failure patients
Cannabis use can be especially harmful for heart failure patients, according to new data presented at SCAI 2025.
FDA approves new AI-enabled wearable cardioverter defibrillator
The newly approved device can be worn for up to a week at a time, with no daily maintenance required, and includes advanced AI algorithms that minimize the risk of false alarms or inappropriate shocks.

Expanding Medicaid linked to better care for heart patients

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.

Atrial fibrillation after TAVR linked to much higher risk of death, heart failure

Researchers tracked data from nearly 7,000 TAVR patients for two years, focusing on all-cause mortality and heart failure hospitalizations.

PaceMate gains a key investor in its heart monitoring technology

Lead Edge Capital is a well-known tech investor that has previously worked with such groups as Spotify, Duo Security and Toast.

New research suggests immunotherapy for AFib could be on the horizon

Targeting immune cells that play a key role in the development of atrial fibrillation could give cardiologists a new way to treat the disease.

Medtronic recalls nearly 350,000 implantable heart devices after 22 injuries

The FDA has categorized this as a Class I recall, meaning the use of these devices could cause “serious injuries or death.”

dissolvable heart monitors for AFib designed by Northwestern and George Washington

New dissolvable heart monitors could help cardiologists battle AFib

The new-look devices are soft, flexible, transparent and roughly the size of a postage stamp.

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.
