Signs of right sided heart failure
Edema, JVD, hepatomegaly/hepatojugular reflux,
Ddx for flash pulmonary edema
PE, asthma, pneumonia
Cardioversion vs defib
Cardioversion is synchronized (dont hit the T wave)
Defib vfib
Treat acute/unstable afib
BB for rate control
<48 hrs: shock
>48hrs or unknown: TEE or anticoagulate for 3 weeks, shock
Both get anticoagulation for 4 weeks after
Multifocal atrial tachycardia
Severe pulmonary disease
3 different P wave morphologies
Most common arrhythmia associated with dig toxicity
Paroxysmal atrial tachycardia with 2:1 block
WPW
Accessory conduction pathway
Narrow complex tachycardia, short PR interval and delta wave
Cannon A waves
When atria and ventricle contract together
Seen in 3rd AVB, pulmonary hypertension, VT
Sick SInus Syndrome
Spontaneous sinus bradycardia
Elderly
ECG changes seen in pericarditis
- Diffuse ST elevation and PR depression
- ST normal
- T wave inversion
- T wave normal
CP that improves with sitting up and leaning forward
Acute pericarditis
Kussmaul sign
JVD fails to decrease during inspiration
Right sided heart problems, PE, restrictive pericarditis
Pericardial knock
abrupt cessation of ventricular filling
When will a CXR show a pericardial effusion?
> 250mL of fluid
“water bottle” appearance
Cardiac tamponade fluid amounts
200mL quickly or 2L slowly
Impairment in cardiac tamponade
Ventricular filling during diastole
Clinical features of tamponade
Elevated JVP (prominent x with absent y)
Narrowed pulse pressure (decreased stroke volume)
Pulsus paradoxus (>10mm decrease in atrial pressure during inspiration)
Muffled heart sounds
Cardiogenic shock (tachypnea, tachycardia, hypotension)
EKG of tamponade
Electrical alternans (not sensitive or specific)
Cause of mitral stenosis
Almost all are rheumatic heart disease
Sequela of long standing mitral stenosis
Asymptomatic until area is ~1.5cm2
Pulmonary HTN, right sided heart failure, afib
Murmur of mitral stenosis
Opening snap followed by a diastolic rumble (murmur increases in length as stenosis worsens)
Distance between S2 and opening snap closer as stenosis worsens
Murmur followed by a loud S1
Common life things that cause symptomatic mitral stenosis
Exercise and pregnancy
Echo of mitral stenosis
Left atrial enlargement
Thick, calcified valve
“fish mouth” opening
Sequela of long standing aortic stenosis
Cardiac output fails to increase with exertion when area falls below 0.7 (<0.8 considered severe)
LVH/LV dilation -> LV dysfunction -> pulling apart of mitral valve -> mitral regurg
Causes of aortic stenosis
Bicuspid aortic vale, calcification with age, rheumatic fever
Murmur/Signs of aortic stenosis
Harsh crescendo-decrescendo murmur that radiates to carotids
Soft S2, S4
Parvus et bardus (delayed carotid upstroke)
Precordial thrill
Murmur/Clinical features of aortic regurg
Diastolic decrescendo murmur at the left sternal border
Wide pulse pressure (increased systolic BP)
Corrigan/water hammer pulse (rapidly increasing pulse that collapses suddenly)
Austin Flint murmur (low pitched diastolic rumble)
Clinical features of tricuspid regurg
Looks like RVF (edema, hepatomegaly etc) Pulsatile liver Prominent V waves in JVP Blowing, holosystolic murmur Afib
Classifying aortic dissection
A: proximal (even if as an extension from descending)
B: Distal; just descending (distal to subclavian)
Manage aortic dissection
BB immediately (lower HR and force of EF), sodium nitroprusside to lower systolic BP
A: surgical
B: medical
Sx of acute arterial occlusion
Pain, pallor, polar (cold), paralysis, paresthesias, pulselessness
Venous ulcers
Not as painful as arterial, over medial malleolus
Sx of peripheral vascular disease
(arterial insufficiency)
Claudication, pain at night (distal metatarsals; improves with foot over bed)
Diminished pulses, hairless, thick toenails
Definition of cardiogenic shock
BP <90 with urine output <20mL/hr and adequate LV filling pressure
Pathophys of chronic bronchitis
Excess mucous production -> inflammation and scarring, smooth muscle hyperplasia -> obstruction
Pathophys of emphysema
Smoke increases activated PMNs and macrophages -> release protease/elastase (relative deficiency of antiprotease)
LFTs in COPD
FEV1/FEV decreased
FEV1 decreased
TLC increased
