markings clearly defined? Shine light directly from temporal side
inspect each iris, markings clearly defined. Shine light directly from temporal side = crescentric shadow medial side
Iris bows abnormally far forward = very narrow angle w cornea, light casts a crescentric shadow medial side (see pp. 235 Bates). This angle increases acute narrow-angle glaucoma (sudden increase in IOP d/t aqueous humor blockage).
118What are you assessing for on the concentric shadow on medial side?
, normal = fairly flat w relatively open angle w cornea therefore no shadow. Narrow angle = increases narrow -angle glaucoma risk (increase in IOP w aqueous humor blocked).

135What is nonproliferative retinopathy?
¡Nonproliferative retinopathy (NPDR) consists of a variable display of nerve-fiber layer infarcts (cotton-wool spots), intraretinal hemorrhages, and hard exudates, and microvascular abnormalities (including microaneurysms, occluded vessels, and dilated or tortuous vessels) primarily in the macula and posterior retina
¡Visual loss in nonproliferative retinopathy is primarily through the development of macular edema (ME)
¡NPDR can be further classified into mild, moderate, severe and very severe categories
§This stratification primarily impacts the risk of progression to proliferative retinopathy, which influences follow up intervals and treatment strategies. Whereas the one-year risks of progression to proliferative retinopathy for mild and moderate nonproliferative retinopathy are 5 and 15 percent, respectively, the severe and very severe categories have respective one year risks of 52 and 75 percent
136What is proliferative retinopathy?
¡ Proliferative diabetic retinopathy (PDR) is marked by the presence of neovascularization arising from the disc and/or retinal vessels, consequences of this neovascularization, including preretinal and vitreous hemorrhage, subsequent fibrosis, and traction retinal detachment. PDR may develop in the setting of prior or coexisting severe nonproliferative changes, or may arise without substantial nonproliferative retinopathy.
¡Visual loss in PDR may occur acutely if bleeding from the abnormal vessels into the vitreous blocks the light path to the retina; however, the blood is often reabsorbed and vision clears spontaneously. More permanent loss of vision may occur through retinal detachment, ischemia of the macula, or combinations of these factors.
137What are the subjective findings of diabetic retinopathy

§Often, severe symptoms Intermittent episodes lasting seconds to minutes, occasionally hours
§Horizontal or horizontal-torsional nystagmus (also positional, fatigues, and suppressed by fixation)
§Normal neurologic exam
§Sometimes associated hearing loss or tinnitus
¡Central vertigo:
§Usually mild continuous symptoms
§All varieties of nystagmus (horizontal, vertical, rotatory)
§No positional association
§Presence of neurologic findings most of the time
144What are the etiologies of peripheral vertigo?
Peripheral
¡Acute peripheral vestibulopathy (APV):
§Vestibular neuritis (most common):
▪Single acute attack continuous rotational vertigo
▪Constant for several days
▪Present even when still
▪No hearing deficits
▪Highest incidence in 3rd-5th decade
§Acute labyrinthitis:
▪Similar to vestibular neuritis but:
▪Associated with hearing deficit
▪May be viral (common), serous, acute suppurative, toxic, or chronic
¡
¡Benign paroxysmal positional vertigo (BPPV):
§Most common cause recurrent vertigo
§Posterior canal, 85-95% of BPPV cases
§Lateral semicircular less common
§Probable cause is loose particles (otoliths) in semicircular canals
§Can be secondary to other entities including trauma and APV
Ototoxic drugs:
§Aminoglycosides
§Antimalarials
§Erythromycin
§Furosemide
¡Ménière disease:
§Episodic vertigo, hearing loss, and tinnitus
¡Acoustic neuroma:

D-DIMER
149What are the s/s of peripheral vascular disease?
¡ROS Intermittent claudication, muscular cramping with exercise; quickly relieved by rest. Pain in buttocks and thighs suggests aortoiliac disease; calf muscle pain implies femoral or popliteal artery disease. More advanced arteriosclerotic obstruction results in pain at rest; painful ulcers of the feet (sometimes painless in diabetics) may result.
¡
¡Physical Examination Decreased peripheral pulses (ankle:brachial index <1.0; <0.5 with severe ischemia), blanching of affected limb with elevation, dependent rubor. Ischemic ulcers or gangrene of toes may be present.
¡
150What causes PACs?
§Occur when an ectopic focus in the atria fires before the next sinus node impulse. P waves usually look different (i.e., either smaller or peaked).
§Rate usually "resets" itself, resulting in one premature beat followed by a normal series of beats in sinus rhythm.
151What are the characteristics of atrial fibrillation?
§No discernible P waves; fibrillatory waves are noted instead.
§PR interval is not measurable (wavy baseline).
§QRS complex is regularly irregular.
§Atrial rate is commonly 300 to 400 bpm or greater.
§Ventricular rate is usually 100 to 160 bpm or greater. B.
§Etiology.
▪Congestive heart failure
▪Hypoxemia
▪Valvular disease
▪Hyperthyroidism
¡Clinical manifestations.
§Patient may be asymptomatic.
§Patient may report palpitations
§Decreased cardiac output leads to hypotension and loss of consciousness.
152What are the characteristics of atrial flutter?
§Sawtooth appearance of flutter waves (F waves), especially if the rhythm strip is turned upside down
§PR interval is not measurable.
§Atrial rate ranges from 240 to 360 bpm.
§QRS complex is usually normal.
§Etiology.
▪Congestive heart failure
▪Hypoxemia
▪Valvular disease
▪Hyperthyroidism
§Clinical manifestations.
▪Decreased cardiac output
▪Hypotension
▪Loss of consciousness
▪Treatment: same as for atrial fibrillation
153What are the characteristics of junctional rhythms?
§Because the beat originates in the atrioventricular (AV) node, usually, no P waves precede QRS complexes.
§Occasionally, P waves are retrograde conducted, resulting in a downward deflection before or after the QRS complex.
§Rate is usually 40 to 60 bpm (i.e., the intrinsic AV node rate).
§Accelerated junctional rhythms have the same criteria, but rates range from 60 to 100 bpm.
¡Rarely seen in adult patients
¡Etiology (common causes).
§Digitalis toxicity
§Theophylline
Dopamine
154What are the characteristics of PVCs?
¡Irritability of the myocardium due to the following:
¡Electrolyte imbalance
¡Hypoxia
¡Acidosis
¡Myocardial infarction
§Other.
¡A stimulus from the ventricle replaces the sinoatrial (SA) node as the pacemaker for one or more beats, and contraction occurs without the usual transmission from the atrium.
¡Clinical manifestations.
§Patients may or may not be aware of PVCs.
§Symptoms are usually related to the number and frequency of abnormal beats.
§Patients may complain of "fluttering" or "palpitations" of the heart.
§On the monitor, PVCs exhibit a wide, bizarre configuration that is very different from that of the normal beat.
¡ Implications.
§PVCs that occur infrequently or have the same focus (i.e., have the same shape), are unifocal
¡An increase in the frequency of these beats is more significant, especially if the PVCs occur more often than 6 times per minute, or if the patient has had a very recent myocardial infarction. PVCs that are the result of more than one focus (i.e., multifocal) are more serious and may precede ventricular tachycardia or ventricular fibrillation.
§The risk is minimal if the beats are isolated.
§The danger increases if beats do the following:
▪ Are frequent (i.e., more than six per minute) I
▪Are multifocal (have different shapes)
155What are the characteristics of ventricular tachycardia?
§Irritability of the myocardium
§Series of ectopic electrical impulses from the ventricles assumes control of the heart rhythm.
¡Clinical manifestations.
§The monitor pattern shows a series of beats with wide, bizarre complexes.
§If conscious, the patient may feel palpitations or may be light-headed or dizzy, or have chest pain.
§Blood pressure usually drops significantly.
§A weak pulse may be present.
§If unconscious, the patient may appear clinically dead and may not have a pulse (if so, treat as ventricular fibrillation) or may demonstrate seizure-like activity.
§ Ventricular rate is 120 to 250 bpm.
¡Implications.
§If untreated, VT produces rapid hemodynamic decompensation caused by inadequate filling and emptying of the ventricles.
§If untreated, VT leads to VF, asystole, and death.
156What are the characteristics of first degree AV block?
§Delay in the impulse from the atria to the ventricles characterized by a PR interval of longer than 0.20 second
§Rhythm is regular, and the QRS complex is not affected.
¡Etiology.
§Occurs in all ages in both normal and diseased hearts
§Drugs.
▪Digoxin
▪Beta blockers
▪Calcium channel blockers
▪Damage to the junction
¡Clinical manifestations: usually asymptomatic
157What are the characteristics of second degree block MOBITZ I?
Second-degree block (Mobitz type I) (Wenckebach)
¡Characteristics.
§Usually transient and occurs at the AV node
§Progressive prolongation of the PR interval until an impulse is completely blocked (dropped)
§Then, the pattern usually repeats.
§ R-R interval decreases prior to the blocked beat. 5. Atrial rhythm is usually regular, and the ventricular rhythm is usually irregular, with progressive shortening of the R-R interval before the blocked impulse.
§QRS complex is not affected.
¡Etiology
§Usually from drug effects (e.g., digitalis, verapamil, propranolol), or
§Myocardial infarction
¡Clinical manifestations.
§Often asymptomatic
§If symptomatic, may see the following:
▪ a. Decreased cardiac output
▪b. Hypotension
c. Loss of consciousness
158What are the characteristics of second degree block Mobitz type II?
Second-degree block (Mobitz type II)
¡Characteristics.
§Usually occurs below the level of the AV node
§Associated commonly with an organic lesion in the conduction pathway
§Associated with poorer prognosis than Mobitz type-I
§PR interval does not lengthen prior to a dropped beat.
§More than one dropped beat may occur in succession. 6. Sometimes associated with widened QRS complex
§Overall, the atrial rate is unaffected, but the ventricular rate is less than the atrial rate.
¡Etiology.
§Most often due to conduction path lesion
§Usually anterior myocardial infarction
§Clinical manifestations: same as second-degree type I.
159What are the characteristics of third degree AV block?
Characteristics.
¡Complete absence of conduction between the atria and the ventricles
¡Atrial rate is unaffected, and the ventricular rate is slower than the atrial rate.
¡Ventricular rate is usually 40 to 60 bpm.
¡PR interval will vary because the atria and the ventricles are depolarized from different pacemakers.
¡Etiology.
§MI is the most common cause.
§May also be caused by digitalis toxicity or any other degeneration of the conduction system
¡Clinical manifestations.
§Otherwise, progressive decrease in cardiac output, loss of consciousness
Asymptomatic if the ventricular rate is adequate

¡Compare to prior ECG if available
§If normal or unchanged, serial ECGs every 10-30 min
¡New ST changes or T-wave inversion suspicious for UA
§T-wave flattening or biphasic T-waves
§≤1 mm ST depression 80 msec from the J point, is characteristic in UA
§Can see evidence of old ischemia, strain or infarct, such as old TWI, Q-wave, ST depression
§Single ECG for acute MI is about 60% sensitive and 90% specific
¡ECG can also be helpful to diagnose other causes of chest pain
§Pericarditis: Diffuse ST elevations, then T wave inversions and pulse rate depression
§Pulmonary embolus S1Q3T3 pattern, unexplained tachycardia and signs of right heart strain
162What are the diagnostic tests and interpretation of angina?
Labs
¡For stable angina, cardiac enzymes not indicated, but if history suspicious for acute MI, should obtain.
¡CK-MB and troponin I or T <50% of patient with UA will have low level troponin elevations CK-MB peaks 12-24 hr, return to baseline in 2-3 days Troponin peaks in 12 hr, return to baseline 7-10 days
¡Hematocrit (anemia increases risk of ischemia)
¡Coagulation profile
¡Electrolytes, especially Cr and K+
Imaging
¡CXR:
§Usually nonrevealing
§May show cardiomegaly, or pulmonary edema, CHF suggests UA or MI.
§May be helpful in identifying other etiologies such as pneumonia, pneumothorax, or aortic dissection
¡Coronary CTA:
§Good for low-risk patients with no known CAD to rule out ischemia as cause of pain in patient if no coronary stenosis
§"Triple rule-out" for ACS, PE, and aortic dissection
¡Bedside echo: To detect wall motion abnormalities and other etiologies of shock, pericardial effusion, pneumothorax
¡Technetium Tc-99 sestamibi (rest): Radionucleotide whose uptake by myocardium is dependent on perfusion
Diagnostic Procedures/Surgery
¡Exercise stress testing: Not appropriate if active chest pain with moderate to high likelihood of ischemia Imaging stress test (sestamibi, thallium, or echo) if baseline ECG abnormalities Early positive (within 3 min) concerning for UA Coronary angiography: Gold standard of diagnosis for CAD

Troponin I/T (increases in the first 3-5 hours; returns to normal values after 5-14 days)* CK-MB is an important marker for reinfarction
Ischemia -T wave inversion, peaked T waved, and ST segment depression *with angina, cardiac changes usually do not persist once pain has been alleviated.
Injury-ST segment elevation greater than 1mm above baseline
Infarction- may produce Q waves (pathologic) greater than 25@ of QRS complex height or more than 1 mm wide (0.04s).
165What causes endocarditis?
§Acute endocarditis is a febrile illness that rapidly damages cardiac structures, seeds extracardiac sites hematogenously, and can progress to death within weeks.
