Complications may, however, occur after cardioversion and we do anticoagulate our patients longer than some[15], but we think that this is justified by the delay in restoration of atrial systole experienced by some patients[16] and because the risk of arrhythmia recurrence is highest in the first month.
However, atrial systole is of greater importance for left ventricular filling in patients with MI (11).
The importance of atrial systole is increased in HCM, and particularly those with diastolic dysfunction are intolerant of atrial fibrillation with rapid ventricular rates.
