Disclaimer: new guidelines as of late 2017

Unlikely to be reflected on PANCE yet.

New BP Guidelines:

Elevated: 120-129/< 80

Stage 1: 130-139/80-89

Stage 2: 140+/90+

Hypertensive crisis: 180+/120+ with patients needing prompt changes in medication if there are no other indications of problems, or immediate hospitalization if there are signs of organ damage.

Medication for Stage 1 only if high ASCVD risk (same calculator used in prescribing statins)

Now Back to the PANCE:

Hypertension

  • Definition

  • Prehypertension 120-139/80-89

  • Stage 1 140-159/90-99

  • Stage 2 160+/100+

  • Urgency 180+/120+ & NO end organ damage

  • Emergency 180+/120+ & end organ damage (HERB)

  • ON 2 DIFFERENT READINGS

  • Symptoms

  • Primary Hypertension is typically asymptomatic

  • Hypertensive emergency

  • Encephalopathy

  • Intracranial hemorrhage

  • Nephropathy

  • Unstable angina/MI

  • Papilledema=malignant hypertension

  • Treatment (non-urgent/emergent)

  • Lifestyle Modifications 1stALWAYS (Including those with Pre-HTN)

  • DASH Diet

  • Lower Sodium

  • Exercise

  • Healthy weight

  • Smoking Cessation

  • Medication Therapy

  • Begin at 140/90 (this is also BP goal)

  • Unless

  • Over age 60

  • Normal Kidneys

  • No Diabetes

  • Then 150/90

  • Which med?

  • 4 Main Classes to Choose From

  • ACE Inhibitor

  • Angiotensin converting Enzyme

  • -“pril”

  • Side Effects:

  • Cough

  • Hyperkalemia

  • Angioedema

  • Contraindications:

  • Renal artery stenosis

  • Pregnancy

  • ARB

  • Angiotensin II Receptor Blocker

  • -“sartan”

  • Side Effects:

  • Hyperkalemia

  • Angioedema

  • Contraindications:

  • Renal Artery Stenosis

  • Pregnancy

  • Calcium Channel Blocker

  • -“dipine”

  • More effective as vasodilators than verapamil and diltiazem

  • Side Effects:

  • Still have some cardiac effects

  • Thiazide Diuretic (HCTZ)

  • Side Effects:

  • Hypokalemia

  • None of the above?

  • Then just pick one!

  • You can max out the dose before adding a 2ndor add a 2ndif goal isn’t met, doesn’t matter

  • NEVER MIX AN ACE AND AN ARB

  • Both inhibit the RAAS

  • Thyroid disease

  • Treatment

  • Urgency

  • Decrease by 25% over 24-48 hours

  • Rest in a quiet room

This episode is less about boards, more about being thorough and thinking about how to process an EKG systemically in order to not miss something. For boards, it’s ok to jump to what is glaring at you. No questions or take away points associated with this podcast.

As promised, here is my EKG Cheatsheet!

Evidence of a pacemaker?

  • Failure to capture

  • Heart doesn’t “capture” signal

  • Pacemaker spike, but no P wave

  • Failure to Pace/Oversensing

  • Pacemaker is over sensing electrical activity

  • HR is slow, pacemaker isn’t initiating beats

  • Failure to sense

  • Pacemaker ISN’T sensing natural heart activity

  • sends unnecessary spikes

EKG Interpretation

1 box=0.04s wide x 1mm high

  • Rate=how fast

  • 6 second strip*10

  • can be used for regular or irregular rhythms

  • May also use 300-150-100-75-60-50 method

  • Refers to # of large boxes in between R waves

  • 1 large box=300bpm, 2 large boxes=150bpm

  • Rhythm MUST be regular

  • Tachycardia is ALWAYS tachycardia (>100bpm)

  • regardless of sinus, junctional, or ventricular tachycardia

  • Sinus

  • Bradycardia >60

  • Normal 60-100bpm

  • Junctional

  • Escape 40-60bpm

  • Accelerated Junctional 60-100bpm

  • Ventricular

  • Idioventricular 20-40bpm

  • Accelerated Ventricular 40-100bpm

  • Rhythm=pattern

  • normal=atria, junction, ventricals

    1. Should be able to march caliper along R-R intervals without adjustments

  • If no, we already know the rhythm is irregular

    1. Do we have distinct P waves?

  • No?

  • Junctional rhythm?

  • inverted or absent p waves

  • normal QRS complex

  • non-compensatory pause

  • Ventricular rhythm?

  • absent p waves

  • wide-bizarre complex

  • pre-mature ventricular contraction with compensatory pause

  • A fib?

  • Yes? Does each P have a QRS?

  • No?

  • A flutter

  • 2nd/3rd degree heart blocks

    1. Determine if regularly irregular or irregularly irregular.

  • P wave

  • Normal=2.5×2.5 boxes

  • Represents atrial depolarization

  • Too wide? (3 boxes)

  • Left atrial enlargement

  • May also be M shaped

  • Left is LONG

  • Too tall? (3 boxes)

  • Right atrial enlargement

  • PR Interval

  • Normal= 0.12-0.2s (3-5 boxes)

  • Too long?

  • Consistent=1st degree heart block

  • Inconsistent= 2nd degree heart block (Type 1 or 2)

  • Too short? = Pre-Excitation Disorder

  • Wolf-Parkinson-White

  • Also has delta wave

  • Lown-Ganong-Levine

  • QRS Complex

  • Normal = less than 0.12s (3 boxes)

  • Too wide?

  • Bundle branch block

  • Left

  • Deep S in V1 (carrot)

  • Broad R in v6

  • Right

  • RsR’ in v1 (rabbit ears)

  • Wide S in v6

  • Ventricular rhythm

  • Wide, bizarre complex with no p wave

  • Height?

  • Right ventricular hypertrophy

During this week’s episode, we’ll be discussing valvular disorders, in essence, heart murmurs.

There are LOADS of Picmonics available for heart murmurs. A couple of my favorites Mitral Regurgitation and Aortic Stenosis.

Systole=ventricles contracting

Diastole=ventricles relaxing & refilling

S1=beginning of systole. AV valves (mitral & tricuspid) are closing. “lub”

S2=end of systole. Semilunar valves closing (aortic & pulmonic) “dub”

Lub, dub, rest, lub, dub, rest

Murmur Accentuation Maneuvers

The following applies to all murmurs except that of hypertrophic cardiomyopathy, in which the opposite is true

  • Position:

  • Aortic=increased with leaning forward

  • Mitral=LLD

  • Increased venous return

  • Squatting

  • Leg raise

  • Lying down

  • Later click in MVP

  • Inspiration

  • Right sided murmurs only

  • Also due to increased venous return

  • Expiration

  • Left sided murmurs only

  • Also due to increased venous return

  • Increased Afterload

  • Handgrip

  • Increases regurgitation murmurs

  • Pushes backward

Aortic Stenosis

  • 1 valvular disease

  • Etiologies:

  • Calcification

  • Bicuspid valve (if under 70y.o.)

  • Systolic, crescendo-descrescendo ejection murmur

  • At right upper sternal border (the location of the aortic valve)

  • With radiation to the carotids

  • Narrowed pulse pressure

  • Pulsus parvus et tardus

  • Small, delayed, carotid pulse

  • Not specific to aortic stenosis

  • Can lead to angina, syncope, LVH, and CHF

  • Tx:

  • VALVE REPLACEMENT

  • Once symptomatic

  • Mechanical valves (vs bioprosthetic) require lifelong anticoagulation

Mitral Stenosis

  • Etio: rheumatic heart disease

  • Early mid-diastolic rumble preceded by an opening snap

  • At apex (location of mitral valve)

  • Increased in left lateral decubitus position

  • Prominent S1 (stenotic mitral valve closes forcefully)

  • Symptoms

  • Pulmonary symptoms

  • Blood backs into lungs

  • Pulmonary htn

  • Atrial fibrillation

  • 2/2 atrial enlargement

  • “mitral facies”

  • Flushed cheeks with facial pallor

  • Treatment:

  • Percutaneous balloon valvuloplasty

  • Younger patients

  • Non-calcified valves

  • Valve replacement otherwise

Mitral Regurgitation

  • Etio:

  • mitral valve prolapse #1

  • papillary muscle dysfunction

  • ischemia/infarction

  • Blowing, holosystolic murmur

  • At Apex (location of mitral valve)

  • Radiation to axilla

  • Blowing=regurg

  • Widely split S2

  • Aortic valve closes early due to decreased LV ejection time

  • Pulmonic valve closes late due to pulmonary htn (increased pressure to overcome)

This week on PA Study Sesh we are starting the cardio chapter and discussing conduction disorders.

Sinus Arrhythmia

  • Appears as normal sinus rhythm, but rhythm is irregular

  • Normal variant

  • INcreases during INspiration

Sinus Bradycardia

  • <60BPM

  • 1cause=vagal stimulation=increased acetylcholine (increased parasympathetic activity)

  • Tx: Atropine (anticholinergic)

Sinus Tachycardia

  • 100BPM

  • Tx: Vagal maneuvers, adenosine, bblockers, CCB, Digoxin (ABCDs)

Sick-Sinus Syndrome

  • Combo of sinus arrest with paroxysms of tachy & brady arrhythmias

  • TX: permament pacemaker if symptomatic

  • If V-tach=with automatic implanatable cardioverter-defibrillator

Premature Atrial Contraction (PAC)

  • Abnormal P wave followed by QRS

  • May be unifocal or multifocal

  • Non-compensatory pause

  • Next normal p wave is not where expected

  • Usually benign, though may increase risk of arrhythmias if combined with other heart abnormalities.

Atrial flutter

  • “saw tooth” waves

  • Tx:

  • Stable: vagal maneuvers, b-blockers, ccbs

  • Unstable: synchronized cardioversion

  • Definitive= ablation

Atrial fibrillation

  • 1 chronic arrhythmia

  • Irregularly irregular with narrow QRS

  • No distinct P waves

  • Loads of causes

  • Often associated with hyperthyroid

  • Also atrial enlargement

  • Increased risk of clots (blood isn’t moving properly out of atria)

  • Tx:

  • Stable: rate control

  • B blockers #1: metoprolol

  • CCBs: Diltiazem or Verapamil (nondihydropyridines)

  • Digoxin if hypotensive or CHF

  • Unstable:

  • Synchronized cardioversion

  • Management:

  • Anticoagulation

  • Factor Xa inhibitors

  • “Xabans”

  • Bind to antithrombin III

  • Dabigatran

  • Direct thrombin inhibitor

  • Warfarin

  • If other drugs contraindicated

  • Dual anti-platelet therapy

  • Aspirin + Clopidogrel

  • Less effective than anticoagulant monotherapy

Paroxysmal Supraventricular Tachycardia (PSVT)

  • 2 types

  • AV nodal reentry #1

  • 2 paths within AV node (one slow & one fast)

  • Av reciprocating

  • Accessory pathway outside the av node

  • Wolff-Parkinson White

  • Lown-Ganong-Levine Syndrome

  • Wide or narrow QRS complex

  • Depends on which pathway is taken first

  • Wolf-Parkinson White

  • Accessory pathway=bundle of Kent

  • Ventricles are “pre-excited”

  • Can develop tachyarrhyhmias

  • EKG:

  • Delta wave

  • Slurred QRS

  • Candle

  • Wide QRS

  • Short PR Interval

  • Management:

  • Avoid av nodal blockers because current may preferentially travel down accessory pathway

  • Lown-Ganong-Levine Syndrome

  • Short PR interval with normal QRS

  • Bundle of James

  • Management (of all PSVT)

  • Narrow complex

  • Vagal maneuvers

  • =increased acetylcholine=decreased heartrate

  • Adenosine#1

  • B or CCBs

  • Wide Complex

  • Amiodarone

This week on PA Study Sesh, we’ll learn about Rheumatology.

A note about ANA, RF, ESR, CRP

ANA: Antinuclear antibodies

Shows antibodies against self

Can be positive in healthy people

Also induced by certain drugs & cancers

NONSPECIFIC

CRP: C-reactive protein

Produced in the early stages of inflammatory process.

NONSPECIFIC

ESR: erythrocyte sedimentation rate “sed rate”

Rate at which rbcs settle

NONSPECIFIC

RF: Rheumatoid Factor

Autoantibody to a fragment of IgG

NONSPECIFIC

In Summary: These are all NONSPECIFIC and only clue you in to the presence of inflammation and auto-immune disease. They do not help you definitively distinguish one disease from another and therefore (in my opinion) are not worth memorizing their absence/presence in each disease for PANCE/PANRE purposes.

Fibromyagia

  • Chronic, widespread muscle pain

  • Middle aged women

  • Associated fatigue, fibro fog

  • Diffuse pain in 11/18 trigger points >3 months

  • Clinical diagnosis

  • Tx: exercise (swimming), OTC pain medication, TCA

Reactive Arthritis (Reiter Syndrome)

  • Autoimmune response to an infection elsewhere

  • Young males most common

  • Arthritis, conjunctivitis/uveitis, urethritis

  • Keratoderma blenorrhagicum (hyperkeratotic lesions on palms/soles)

  • s/p chlamydia #1, may also follow gonorrhea or GI infections

  • Labs: Often HLA B-27 + (young males like ankylosing spondylitis)

  • Can’t pee, can’t see, can’t climb a (bamboo) tree, can’t sleep with me

  • Tx: NSAIDS

  • Abx if infection not treated

Gout
