When you are calculating regular rhythms, the most accurate method is to count

number into 1500.
The rate for irregular rhythm is based on the ______________ strip method.
(small or large) (positive or negative)
Q waves occurring on the oscilloscope are ____________________ deflections.
The rhythm for sinus bradycardia is __________________ with the PR intervals
___________________ and the PP intervals _________________________.
Administer ______________ when you treat sinus bradycardia with hypotension.
The casualty's heartbeat rhythm is regular (RRI and PPI are constant). The atrial
and ventricular waves are equal to or greater than 100 beats per minute. The P
wave is uniform with one P wave appearing in front of every QRS complex. The
P-R interval is constant between 0.12 and 0.20 seconds. The QRS measures less
than 0.12 seconds. Which cardiac dysrhythmia is the casualty suffering from?
A soldier in the field is experiencing atrial fibrillation. His pulse is rapid.
Treatment is to ______________________________________and monitor him.
