Typical atrial rate in atrial flutter – MCQ – MCQ

Typical atrial rate in atrial flutter is around – Correct answer: c) 300/min

Atrial flutter is a macro re-entrant arrhythmia with a large re-entry circuit. Usually it manifests with 2:1 conduction ratio and a ventricular rate of 150/min. Conduction ratio can be 3:1 or 4:1 or sometimes varying so that irregular ventricular rhythm can occur.

Atrial flutter being a macro re-entrant arrhythmia, is the arrhythmia most sensitive to electrical cardioversion. It can be converted with low energy direct current (DC) shocks in the range of 25 Joules, while atrial fibrillation requires higher levels of energy as it has multiple small wavelets of re-entry.
