patients with right atrial dilation caused by obstructive
lung disease and heart failure.
A CHADS2 risk score of 2 Anticoagulation therapy is recommended for a

C- Congestive Heart Failure - 1 pt
H-Hypertension or treated hypertension - 1pt

S-Prior stroke of TIA- 2 pts
, The atrial rate differentiates atrial tachycardia from
atrial flutter. This rate difference is particularly
pertinent when the clinician is attempting to discern
whether the arrhythmia is an atrial tachycardia with a
heart block (as seen in digitalis toxicity) or an atrial

tachycardia rate (P-wave rate of 140-250 per minute) is
slower than an atrial flutter rate (P-wave rate of 250-
350 per minute). It is important for the clinician to
remember that the P-wave rate needs to be counted
separately from the QRS rate.
What block is observed 1st degree
with a regular rhythm and
only a prolonged P-R
interval?
What block occurs in the 2nd degree- Mobitz type I

progressive lengthening
of the P-R interval until a
QRS complex (ventricular
contraction) is dropped?
What block occurs within 2nd degree- Mobitz type II
or below the bundle of
His, with a P-R interval that
remains fixed. The
conduction ratio (P waves
to QRS complexes) is
commonly 2:1, 3:1, or 4:1.?
