Flashcards in 16)Ischemic heart disease - management of the acute myocardial infarction complicated with rhythm and conduction disorders, with hypo- and hypertension, with heart failure. Deck (11):
1

if the ischemia affects the right coronary artery what is this importantly feed ?

cells of the san node
ischemia and necrotic cells cannot control their ion currents across their membranes become electrically unpredictable

ischemia can also affect the conductive system

2

what is the management of acute myocardial infraction with ventricular tachycardia ?

lidocaine thorugh iv - class 2

adr
CNS excitation: nervousness, agitation
CNS depression- respiratory depression
headache , dizziness
tinnitus

amiodarone - class 3
peripheral phlebitis ,
long term - pulmonary fibroiis , thyroid abnormalities

3

what is the management with atrial fibrillation ?

digoxin

gynecomastia , dizziness and changes in mood

4

AV branch block 1st degree treatment

1st degree is monitoring

5

ІІ degree Wenckebach type significant bradicardia treatment

atropine - antimuscuranic

dry mouth, large pupils , urinary retention

if no effect - temporary electrocardiostimulation

6

ІІ degree type Mobitz II and III degree AV block in combination with HR bellow 40/min or hypotension or heart failure treatment ?

Temporary electrocardiostimulation

7

heart failure can occur if the myocardial infraction is large has what treatment

mild and moderate heart failure - furosemide
result not sufficient fusion with nitroglycerin

if sever heart failure to shock - give oxygen therapy
follow up by blood gas analysis
presence of hypotension - reduced kidney perfusion - dopamine and
pulmonary congestion - dobutamine

8

is papillary muscle rupture or valvular problems ?

surgery

9

if there is septal rupture ?

surgery

10

rupture of the myocardium treatment ?

surgery

11

how does hypertensive crisis occur in acute myocardial infraction

autonimc nervous system activated - leading to tachycardia and vascocnsitricton

furosemide given
