INVESTIGATIONS

ECG shows uncoordinated atrial activation with rapidly oscillating, fibrillatory waves that vary in amplitude, shape, and timing.[21]January CT, Wann LS, Calkins H, et al. 2019 AHA/ACC/HRS focused update of the 2014 AHA/ACC/HRS guideline for the management of patients with atrial fibrillation: a report of the American College of Cardiology/American Heart Association task force on clinical practice guidelines and the Heart Rhythm Society in collaboration with the Society of Thoracic Surgeons.

No differentiating signs/symptoms

INVESTIGATIONS

Generally, by ECG, atrial tachycardia has isoelectric intervals between the P waves in all leads. At very high atrial rates, it may be extremely difficult to distinguish the two.[21]January CT, Wann LS, Calkins H, et al. 2019 AHA/ACC/HRS focused update of the 2014 AHA/ACC/HRS guideline for the management of patients with atrial fibrillation: a report of the American College of Cardiology/American Heart Association task force on clinical practice guidelines and the Heart Rhythm Society in collaboration with the Society of Thoracic Surgeons.
