are susceptible to termination with pacing. The sine-qua non of a reentrant arrhythmia is the ability to reproducibly initiate and terminate the tachycardia by critically timed extrastimuli.

We retrospectively analyzed two groups of paroxysmal AF-related tachycardia-bradycardia syndrome patients who underwent catheter ablation of AF (ABL group) or pacemaker implantation (PM group ...

Sinus tachycardia is recognized on an ECG with a normal upright P wave in lead II preceding every QRS complex. This indicates that the pacemaker is coming from the sinus node and not elsewhere in ...

Multifocal atrial tachycardia is a tachycardic version of wandering atrial pacemaker in which the atrial rate is greater than 100 beats per minute. Multifocal atrial tachycardia occurs when ...

Tachycardia and bradycardia are easy to identify ... the treatments can be shared. To remedy this, a pacemaker is implanted to regulate the heartbeat by generating an artificial electrical impulse.
