increase LV volume how
squatting, leg raise
decrease LV volume how
valsalva, standing
what movement will accenuated HOCM
standing
3rd degree heart block first line tx
transcutaneous pacing
sinus rhythm with inspiration and expiration
rhythm increases with inspiration
1st degree AV block
PR interval prolonged (>0.20).
wenkebach
mobitz 1
mobitz 1 vs 2
1: wenkebach: progressive PR lengthening then dropped qrs
2: constant prolonged PR interval then dropped qrs
which av block seen in pts with structural hrt disease
mobitz 2
sawtooth pattern on ekg
atrial flutter
a flutter
-rate
- ecg picture
300 beats/min
sawtooth
most common chronic arrhythmia
a fib
afib vs aflutter
aflutter has one irritable atrial foci, afib has multiple
4 types of a fib
paroxysmal, persistant, permanent, lone
ashman’s phenomenon
occasional abberrantly conducted beats (wide QRS) after short R-R cycles
Afib tx
stable: rate control with BB or CCD(D/V)
digoxin is BB/CCB contraindicated
unstable: direct current synchronized CV
anticoagulation and cardioversion
AF > 48 hours: anticoagulation at least 3 weeks before CV
AF < 48 hours: anticoagulation for 4 weeks after CV
CHA2DS2-VASc
chronic oral anticoagulation for score of or higher
CHF, HTN, Age>75(2), DM, Stroke/TIA/Thrombus(2), Vascular disease(prior MI, aortic plaque, PAD), age 65-74, sex(female)
dabigatran
direct thrombin inhibitor(binds and inhibits thrombin)
non vitamin K antagonist oral anticoagulant
rivaroxaban, apixaban, edoxaban
factor 10a inhibitors
non vitamin K antagonist oral anticoagulant
pts for warfarin
severe CKD, contraindicated to use carbamazepine, phenytoin, cost issue
PSVT most common type
AV node re-entrant tachycardia
PSVT common finding on ECG
orthodromic: regular narrow complex tachycardia.
PSVT tx
-stable(narrow and wide)
-unstable
-definitive
stable, narrow: adenosine and vagal manuevers
stable, wide: amiodarone. Procainimide if WPW suspected.
unstable: direct current synchonized CV
definitive: radiofrequency catheter ablation
multifocal atrial tachycardia classically associated with what.
ECG
tx
COPD
heart rate >100, 3 or more P wave morphologies
verapamil or BB
WPW
what pathway
tx
avoid what
bundle of kent
procainimide preferred. amiodarone
lupus like syndrome
avoid AV nodal blocking agents
Etiologies of myocarditis
Infectious, viral most common, especially in tarot, viruses and coxsackievirus b and toxoplasmosis, Lyme disease
Auto immune think of Lupus and rheumatoid arthritis, polymyositis
Clozapine
Myocarditis symptoms
Fever, myalgia, malaise for a few days, followed by symptoms of systolic dysfunction, ( dilated cardiomyopathy)
S3 gallop
Megacolon, pericarditis
Myocarditis gold standard diagnostic test, and other tests
Gold standard is the endomyocardial biopsy
Echo; vent systolic dysfunction
Saddle shaped ST elevation
Myocarditis
Vent tachycardia is usually due to what
Underlying heart disease, ischemic heart disease
V tachycardia treatment
Stable
Unstable with pulse
No pulse
Stable: amio, lido, procainimide
Pulse: synchronized cv
No pulse: defib, unsynchronized cv + cpr
What electrolyte abnormalities can cause VTEC and torsades
Low magnesium, low, potassium, and low calcium
V fib, patient presentation and management
Unresponsive, pulse, syncope
Un synchronized cardioversion (defib) + cpr
Brugada
Rt bbb
Prostaglandins
PDA and ductus arteriosis
They keep ductus open and close pda
Most common innocent murmur
Still murmur
Most common innocent murmur
Still murmur
Systolic and diastolic pediatric murmurs, which are innocent and concerning
Systolic or innocent and diastolic are pathological
Murmur that may develop paradoxical emboli
Asd
Describe murmur for ASD
Systolic ejection crescendo de crescendo at pulmonic area
Wide, fixed S2 split that does not vary with respirations
Systolic ejection crescendo de crescendo at pulmonic area
Wide, fixed S2 split that does not vary with respirations
Asd
Systolic ejection crescendo de crescendo at pulmonic area
Wide, fixed S2 split that does not vary with respirations
Asd
Describe the PDA murmur
Continuous machine like murmur loudest at the pulmonic area
Wide pulse pressure/bounding, peripheral pulses, S2
Continuous machine like murmur loudest at the pulmonic area
Wide pulse pressure/bounding, peripheral pulses, S2
Pda
pathophys of pda
continued prostanglandin E1 production and low arterial oxygen content promotes patency
congenital heart defect often associated with bicuspid aortic valve
coa
narrowing occurs where in coa in adult and infants
adult: occurs distal to the ductus arteriosum
infants: occurs proximal to ductus arteriosum
s/s coa
claudification bilateral, DOE, syncope
neonatal presentation of coa
failure to thrive, poor feeding 1-2 weeks after birth
describe murmur of coa
systolic murmur radiating to the back, scapula, or chest
coa cxr
posterior rib notching; 3 sign
failure to thrive, poor feeding 1-2 weeks after birth
