· After atrial fibrillation, atrial flutter is the most important and most common atrial tachyarrhythmia. Although it was first described 80 years ago, techniques for its diagnosis and management have changed little for decades. The diagnosis rested almost entirely with the 12 lead ECG, and treatment options included only the use of a digitalis compound to slow and control the ventricular for patients with chronic refractory atrial tachyarrhythmias (atrial fibrillation or flutter), which might trigger ventricular pacing • Dual-chamber and single-chamber atrial pacing in patients with chronic refractory atrial tachyarrhythmias • Asynchronous pacing in the presence (or likelihood) of competition between paced and intrinsic rhythms Arrhythmia, also known as cardiac arrhythmia or heart arrhythmia, is a group of conditions in which the heartbeat is irregular, too fast, or too slow. The heart rate that is too fast – above beats per minute in adults – is called tachycardia, and a heart rate that is too slow –

If you are located in the United States, please view the information below. See the device manual for detailed information regarding single chamber pacemaker atrial fibrillation instructions single chamber pacemaker atrial fibrillation use, the implant procedure, indications, contraindications, warnings, precautions, and potential adverse events.
If using an MRI SureScan ® device, single chamber pacemaker atrial fibrillation, see the MRI SureScan ® technical manual before performing an MRI. Implantable Pulse Generators IPGs are indicated for rate adaptive pacing in patients who may benefit from increased pacing rates concurrent with increases in activity.
