What does a 1st degree heart block -lengthened PR interval
look like
-treat reversible causes like ischemia,
What is the treatment increased vagal tone, or meds
-progressive PR prolongation for several
What is a second degree Wenckebach beats prior to non-conducted P wave
(Mobitz type 1) heart block look
like -treat reversible causes like ischemia,
increased vagal tone or meds
What is the treatment -pacemaker if there is symptomatic bradycardia
-PR interval remains unchanged prior to
What does a second degress mobitz nonconducted P waves
type 2 heart block look like
-treat reversible causes like ischemia,
What is the treatment increased vagal tone or meds
-pacemaker
-P waves dont correlate to QRS
What does a third degree heart block
look like
-treat reversible causes like ischemia,
increased vagal tone or meds
What is the treatment
-pacemaker
-if a short run = alert and stable
What are signs and =if prolonged run = hypotension, Myocardial
symptoms of ventricular ischemia, syncope, CP, dyspnea
tachycardia -sudden cardiac death
, -IV Mg
What is the management of torsades
What is the management of -antiarrhythmics such as amiodarone, lidocaine, and procainamide
ventricular tachycardia -cardioversion if pt remains unstable
-if a short run = alert and stable
What are the signs and
=if prolonged run = hypotension, Myocardial ischemia, syncope, CP, dyspnea
symptoms of ventricular
-sudden cardiac death
fibrillation
What is the treatment of -treat underlying cause
ventricular fibrillation -electric defibrillation
-low stroke volume: dehydration, hemorrhage, vomiting, diarrhea, burns,
valve problems, aortic dissection, ventricular septum or free wall
What are causes of hypotension rupture
-brady or tachy HR
-sepsis, adrenal insufficiency, vasodilating drugs, neurogenic shock
-orthostatics due to antipsychotics, diuretics, ACEI, vasodilators, methyldopa,
-SBP <90 or >30 below baseline
-cyanosis
-oliguria
What are signs and
-cool clammy extremities
symptoms of hypotension
-weakness
-presyncope/syncope
-altered mental status
What is the workup for hypotension if -echo
you suspect cardiogenic shock
-treat underlying cause
-IVF
What is the management for hypotension
-pressors = dopamine, dobutamine
-intraaortic baloon pump
-CP, SOB, diaphoresis
-jaw, neck, shoulder pain
What are the signs and symptoms of
-CP > 30 minutes that is not response to nitro
an acute MI
-tachy/brady
-S3 or S4
What 3 groups of individuals have -women, diabetics, and the elderly
atypical presentation of acute MI
-EKG within 10 minutes and repeat every 10 minutes if initial is non diagnostic
(early peaked T waves, ST elevation, Q waves)
What is the workup for a suspected MI
-cardiac consult
-ECHO to determine cardiac function
T or F: the presence of LBBB or T
pacing spikes makes the EKG difficult
to interpret in the setting of MI
