Sizing as small as a nickel, as thin as a pill, this pacemaker used highly progressive technology to become of use cardiac patients. During a trial run, this Medtronic Micra Transcatheter Pacing ...

A pacemaker is a small electronic device that helps keep the heart beating regularly. It can represent a life-changing treatment for heart conditions such as arrhythmias. It is generally not too ...

Tiny device can be inserted with a syringe, then dissolves after it's no longer needed. (Nanowerk News) Northwestern University engineers have developed a pacemaker so tiny that it can fit inside the ...

A pacemaker is an electric medical device that’s generally about the size of a matchbox. A surgeon implants it under your skin to help manage irregular heartbeats called arrhythmias. Pacemakers can ...

Lipids bind to pacemaker ion channels to unlock their gates. Top: Side view of the structure of SthK channels (blue) with bound lipids (orange). Bottom: Bottom view of the channel pore opening as it ...

In the normal heart, the lower chambers (ventricles) pump at the same time and in sync with the heart's upper chambers (atria). Cardiac resynchronization therapy (CRT), also called biventricular ...

A: Baseline electrocardiogram of the patient in case 2 demonstrating sinus rhythm with right ventricular pacing. B: The presentation electrocardiogram of the patient in case 2 with pacemaker failure ...

A pacemaker can greatly improve daily life, and many people can return to normal life quickly. However, it is important to maintain the device and be aware of certain lifestyle changes. A pacemaker is ...

Defibrillators use electrical shocks to restore a normal heart rate, especially in cases of life threatening arrhythmias or sudden cardiac arrest, while pacemakers use low-energy electrical pulses to ...
