Question

1. in which type of arrhythmia do the atria contract very quickly and out of sync with the rest of the heart because of an error in the hearts electrical system? ventricular tachycardia atrial flutter bradyarrhythmia atrial fibrillation

Explanation:

• Ventricular tachycardia: Affects ventricles, not atria.
• Atrial flutter: Atria contract quickly (250 - 350 beats/min) in a regular, coordinated but "out - of - sync" way with ventricles due to electrical system error.
• Bradyarrhythmia: Characterized by slow heart rate, not rapid atrial contraction.
• Atrial fibrillation: Atria quiver chaotically (350 - 600 beats/min), not coordinated quick contraction as described.

Answer:

atrial flutter
