EKG and medications Flashcards
Normal length of a cardiac cycle?
0.8 seconds
What meds would you use to treat angina?
- nitrates
- beta blockers
- Ca channel blockers
What meds would you use to treat post-MI patients?
- aspirin
- beta blockers
- statin
- ACE inhibitor
suffix for beta-blockers?
lol
suffix for Ca+ channel blockers?
pines
suffix for ACE inhibitors?
pril
action of beta-blockers?
reduce BP by reducing heart rate
action of Ca+ channel blockers?
disrupt movement of calcium through calcium channels
- treats high BP, angina, abnormal heart rhythm
- decrease contractility
action of ACE inhibitors?
treats HTN and congestive heart failure
- inhibits the conversion of angiotensin I to II
action of diuretics?
promotes production of urine
Identify the rhythm: sinus rhythm with a HR slower than 60bpm
sinus bradychardia
Identify the rhythm: sinus rhythm with an elevated rate greater than 100 bpm
sinus tachycardia
Identify the rhythm: sinus rhythm with a rate between 60-100 bpm
normal sinus rhythm
Identify the rhythm: another region of the atria depolarizes before the SA node and thus triggers a premature heartbeat
PAC sinus rhythm
What regulates the heartbeat during normal sinus rhythm?
SA node
Identify the rhythm: extra, abnormal heartbeats that begin in one of the heart’s ventricles….causes a skipped beat feeling
PVC
Identify the rhythm: atria beat too quickly (saw-tooth)
atrial flutter
Identify the rhythm: irregular, rapid heartbeat
atrial fibrillation
Identify the rhythm: a pulse rate of more than a 100 beats with at least 3 irregular heartbeats in row…. the ventricles are beating rapidly.
ventricular tachycardia
Identify the rhythm: a rapid heartbeat that develops when the normal electrical impulses of the heart are disrupted.
supraventricular tachycardia
What is a disturbance in the normal rhythm of the electrical activity of the heart that arises in the ventricles?
ventricular dysrhythmia
rhythms that originate in the atria?
atrial rhythms
What 5 medications should you give a patient with MI?
- ACE inhibitor
- plavix
- aspirin
- beta-blocker
- statin
Why is an MI patient on 2 blood thinners?
- aspirin is more long lasting
- plavix = p2y12 inhibitor –> preventing additional aggregation
