Rules for Ventricular Standstill
Regularity: P-P interval will usually be regular. The R-R interval is not able to be measured because there are no QRS complexes.
Rate: The atrial rate is between 60 and 100 beats/min. P WAVE: There are P waves present and normally uniform. They are not followed by a QRS comlex. PRI: PRI is unable to be measured due to no QRS comlexes being present. QRS: QRS complexes are not present. This means there is no ventricular activity.
