|
what are the life threating arrhythmias
|
Ventricular tachy
MI c PVC's SVT c hypotension |
|
|
what is the difference btw stable and unstable V Tach
|
mental status and BP
|
|
|
sick sinus synd
|
tachy and brady rythms usually seen in the elderly
near syncope and syncope |
|
|
Pre-excitation synd
|
short PR interval
or Delta wave c tachydysrythmia |
|
|
what should you do to confirm CAD
|
a stress test
|
|
|
signs of thyrotoxicosis
|
Tachy
fever dehydration exopthalmos thyromegaly Hx of thyroid disease |
|
|
signs of pheochromocytoma
|
HTN
Tachy ele catecholamines |
|
|
what are the characteristic heart sounds for an MVP
|
Mid-systolic click c late systolic murmur
"click-murmur syndrome" |
|
|
what is the most common click
|
systolic ejection click (aortic or pulmonic valves)
|
|
|
key points to remember about SVT
|
narrow QRS
vagal maneuvers reduce them (like valsalva) |
|
|
what do you order if you suspect MVP?
|
an ECHO
|
|
|
MVP key points
|
More common in females age 14 - 30
most asymptomatic ECHO shows LV dilation and inc LV wall thickness Mid to late systolic click followed by murmur sudden death is a rare complication EKG- ventricular arrhythmia's (paroxysmal SVT & VT) |
|
|
What has the greatest effect on mortality rates in the treatment of MI's
|
if you can initiate thrombolytic therapy within the first 1-2 hours
mortality=1.3% |
|
|
what are the benefits to thrombolytic therapy for MI's within 2-12 hours
|
though there wont be a great deal of myocardial salvage, there will be: less adverse ventricular remodeling, reduced aneurysms, and improved electrophysiologic stability
|
|
|
how do you recognize an acute MI based on history
|
Pressure, squeezing, heaviness, something sitting on my chest
radiation of pain to arms, jaw, teeth diaphoresis, N/V, dyspnea, syncope, palpitations, edema, cough, confusion, weakness DM, Male, smoker, over 50, FH |
|
|
clinical presentations of MI on PE
|
altered mental status
poor perfusion diaphoresis rales JVD S3 S4 bradycardia |
|
|
EKG of AMI, inferior wall
|
ST segment elevation in leads I, II, aVF, V1-4
Must run serial EKGs |
|
|
initial therapeutic intervention for MI
|
Airway
Breathing- supp O2 Circulation- distal pulse and BP Access line immediately |
|
|
further therapeutic intervention for MI (after ABCs)
|
1- thrombolytic therapy
2- B-blockers and Ca++ channel blockers 3- NTG 4- anti-inflammitory agents 5- Aspirin and heparin |
|
|
effects of NTG treatment
|
dec preload and afterload
vasodilation of CAs poss hypotension- resolved w/ IV saline 250-500 cc bolus |
|
|
effects of morphine use in MIs
|
analgesic
anti-anxiety dec O2 consumption vasodilation (2-5 mg every 5 to 30 min) |
|
|
use of and contraindications for B-blockers in the treatment of MI
|
decreased HR, contractility
contra: CHF, COPD, reactive airway disease, Bradycardia, Hypotension |
