1
Q

Normal length of a cardiac cycle?

A

0.8 seconds

2
Q

What meds would you use to treat angina?

A
  • nitrates
  • beta blockers
  • Ca channel blockers
3
Q

What meds would you use to treat post-MI patients?

A
  • aspirin
  • beta blockers
  • statin
  • ACE inhibitor
4
Q

suffix for beta-blockers?

A

lol

5
Q

suffix for Ca+ channel blockers?

A

pines

6
Q

suffix for ACE inhibitors?

A

pril

7
Q

action of beta-blockers?

A

reduce BP by reducing heart rate

8
Q

action of Ca+ channel blockers?

A

disrupt movement of calcium through calcium channels

  • treats high BP, angina, abnormal heart rhythm
  • decrease contractility
9
Q

action of ACE inhibitors?

A

treats HTN and congestive heart failure

- inhibits the conversion of angiotensin I to II

10
Q

action of diuretics?

A

promotes production of urine

11
Q

Identify the rhythm: sinus rhythm with a HR slower than 60bpm

A

sinus bradychardia

12
Q

Identify the rhythm: sinus rhythm with an elevated rate greater than 100 bpm

A

sinus tachycardia

13
Q

Identify the rhythm: sinus rhythm with a rate between 60-100 bpm

A

normal sinus rhythm

14
Q

Identify the rhythm: another region of the atria depolarizes before the SA node and thus triggers a premature heartbeat

A

PAC sinus rhythm

15
Q

What regulates the heartbeat during normal sinus rhythm?

A

SA node

16
Q

Identify the rhythm: extra, abnormal heartbeats that begin in one of the heart’s ventricles….causes a skipped beat feeling

A

PVC

17
Q

Identify the rhythm: atria beat too quickly (saw-tooth)

A

atrial flutter

18
Q

Identify the rhythm: irregular, rapid heartbeat

A

atrial fibrillation

19
Q

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.

A

ventricular tachycardia

20
Q

Identify the rhythm: a rapid heartbeat that develops when the normal electrical impulses of the heart are disrupted.

A

supraventricular tachycardia

21
Q

What is a disturbance in the normal rhythm of the electrical activity of the heart that arises in the ventricles?

A

ventricular dysrhythmia

22
Q

rhythms that originate in the atria?

A

atrial rhythms

23
Q

What 5 medications should you give a patient with MI?

A
  • ACE inhibitor
  • plavix
  • aspirin
  • beta-blocker
  • statin
24
Q

Why is an MI patient on 2 blood thinners?

A
  • aspirin is more long lasting

- plavix = p2y12 inhibitor –> preventing additional aggregation

25
Q

What is an iontrope?

A

manipulates the contractility of the heart

26
Q

What medication do you give to a patient with congestive heart failure and why?

A

diuretic – to get rid of the edema
