The rhythm is regular at a rate of 120 beats/min. A pacemaker stimulus occurs before each QRS complex (→). This is ventricular pacing. Because the pacing rate is 120 beats/min, the mode of pacing must ...

Having an accelerated junctional rhythm occurs when the atrioventricular node in your heart beats too quickly. It happens as a result of damage to your heart’s primary natural pacemaker. There’s no ...

When Bill Rushmore, a cybersecurity engineer with General Motors, talks about his next upgrade, he isn't referring to a car. Eventually, Rushmore will need a replacement for his current pacemaker to ...

Junctional rhythm is an irregular heart rhythm that stems from a natural pacemaker in the heart known as the atrioventricular junction. The heart has several built-in pacemakers that help control its ...

The cardiac pacemaker harmlessly dissolves over the course of 35 days. (Courtesy: Northwestern University) Temporary cardiac pacemakers provide essential pacing for patients with short-term heart ...

JACKSONVILLE, Fla. (Ivanhoe Newswire) – Each year, 200,000 people will undergo a surgery to have a pacemaker implanted. Most pacemakers last six to 10 years. The biggest problem with traditional ...

Your heart has an internal pacemaker called the sinus node. It's a group of cells, located on top of your heart, that sends electrical signals into the heart and controls your heartbeat. Sometimes, ...

Defibrillators and pacemakers help the heart maintain a regular rhythm. Defibrillators deliver a shock if the heart goes into arrhythmia. Pacemakers use electrical impulses to keep the heart from ...

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 ...

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 ...
