Single-chamber ventricular leadless pacemakers do not support atrial pacing or consistent atrioventricular synchrony. A dual-chamber leadless pacemaker system consisting of two devices implanted ...

This story is part of a series on the current progression in Regenerative Medicine. This piece discusses the regeneration of the cardiovascular system. In 1999, I defined regenerative medicine as the ...

When your electrical system is working normally, the two upper chambers of the heart (atria) contract and pump blood into the two lower chambers (ventricles) in a well-coordinated way. This results in ...

The Aveir DR dual-chamber leadless pacemaker system (Abbott) performs well out to 1 year in patients largely treated for sinus node dysfunction or atrioventricular (AV) block, according to extended ...

Last week, Abbott began the commercial launch of its new leadless pacemaker, which it believes is a historic development in the world of cardiac rhythm devices. Aveir DR is a better option than ...

Narrow QRS complexes occur regularly. This tracing suggests either atrial flutter or ventricular tachycardia. It is not atrial flutter, however. If it were, the QRS complexes occurring regularly would ...

Cardiac implantable electronic devices (CIEDs) constitute a major breakthrough in the management of heart rhythm disorders. These devices largely include bradycardia pacemakers, biventricular ...

Estimates suggest that around three million Americans are living with cardiac pacemakers, according to the American Heart Association. Now, thanks to MountainStar Healthcare, a new kind of pacemaker – ...

The human heart is a highly complex pump made of muscle, complete with its own electric power system, supplying the energy and oxygen it needs to function. The heart’s pumping action is regulated by ...

LARGO, Fla. — A new type of pacemaker is on the market and now helping patients with heart issues in Florida. Danette Strange-Gay, the patient, hopes to be a kidney transplant recipient after years of ...
