bradycardia
Hold if HR is below
50-60 bpm
Avoid stopping medication _________
abruptly
What effect does it have on HR?
decreases HR
Used after this cardiac event
Myocardial infarction
reason patient feels tired
low HR/BP
hold if SBP is below
90-100
Caution when changing positions because of
orthostatic hypotension
What effect does it have on contractility?
Decreases contractility
Helps control these abnormal rhythms
tachyarrhythmias

Used in this chronic pumping problem
heart failure
Extremity temperature change
cold hands and feet
