Pacing Clin Electrophysiol. 2008;31(2):229-231. A 52-year-old man was admitted in our institution with cranial traumatism due to a syn-copal episode that occurred while he was walking. Several weeks ...

At times it is difficult to distinguish atrial fibrillation from atrial flutter on the ECG. This example shows coarse "fibrillatory waves" in the setting of atrial fibrillation. This are of varying ...

Conventional dual-chamber pacing maintains atrioventricular synchrony but results in high percentages of ventricular pacing, which causes ventricular desynchronization and has been linked to an ...

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 ...

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 ...

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 ...

At times it is difficult to distinguish atrial fibrillation from atrial flutter on the ECG. This example shows coarse "fibrillatory waves" in the setting of atrial fibrillation. This are of varying ...

A new research study shows that artificial intelligence (AI) can detect the signs of an irregular heart rhythm -- atrial fibrillation (AF) -- in an electrocardiogram (EKG), even if the heart is in ...

A common test that records the heart's electrical activity could predict potentially serious cardiovascular illness, according to a new study. A common test that records the heart's electrical ...
