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 ...

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 ...

Atrial fibrillation is a well-known risk factor for stroke that often remains undetected; yet, the benefit of screening of asymptomatic individuals remains unclear. A recent randomized trial ...

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 ...

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 ...

When transvenous pacing is unsuitable, leadless cardiac pacemaker implantation can be used during the evidence generation period for dual-chamber pacing or right atrial pacing alone for ...
