Cardiomyopathy

Impaired Systolic Function
Dilated Cardiomyopathy Dilated cardiomyopathy is the most common type (95%) of cardiomyopathy and is a condition in which an index event or process (such as an MI) damages the myocardium, weakening the heart muscle resulting in reduced strength of ventricular contraction, and dilation of the left ventricle.

  • Reduced contraction strength, large heart
  • Etiology: caused by Ischemia (CAD, MI, arrhythmia), genetics, excess alcohol, postpartum, chemotherapy, endocrine disorders
  • Physical exam: Dyspnea, S3 gallop, rales, jugular venous distention - systolic heart failure

 

Dilated Cardiomyopathy

Treatment:

  • Abstain from alcohol
  • Medications: ACE inhibitors, diuretics
Impaired Diastolic Function
Hypertrophic Cardiomyopathy Hypertrophic portion of septum - LV outflow tract is narrowed - during systole and obstruction worsened with increased contractility

 

Hypertrophic Cardiomyopathy

Presentation: Young athlete with a positive family history has sudden death or syncopal episode

  • Inherited autosomal dominant
  • Presents in early adulthood
  • Not to be confused with hypertrophy of elite athlete
  • Screen family members

Physical Exam:

  • Sustained PMI, bifid pulse, S4 gallop
  • Murmur: High pitched mid-systolic murmur at LLSB. Increased with Valsalva and standing (less blood
    in the chamber).

    • Decreased with squatting (more blood in chamber)
    • Increased with Valsalva or standing

Treatment:

  • Refrain from vigorous physical activity
  • Medical: Beta blockers or calcium channel blockers
  • Surgical: Surgical or alcohol ablation of hypertrophied septum and defibrillator insertion
Restrictive Cardiomyopathy Right heart failure with a history of an infiltrative process Restrictive Cardiomyopathy

Etiology: Amyloidosis, sarcoidosis, hemochromatosis, scleroderma, fibrosis, and cancer

Physical Exam:

  • Pulmonary HTN present
  • Normal ejection fraction, normal heart size, large atria, normal left ventricular wall, early diastolic filling

Treatment: Non-specific. Diuretics, ACE inhibitors, Calcium channel blockers

Conduction Disorders

Sinus Rhythm

Normal Sinus Rhythm

normal-sinus-rythm

A normal sinus rhythm refers to both a normal heart rate and rhythm. Normal heart rates are from 60 to 100 beats per minute. The shape of the electrocardiogram (EKG) tracing will exhibit certain key attributes to be considered normal, as discussed below. With normal sinus rhythms, the heart beat's electrical impulse originates in the sinoatrial node (SA). The P waves are upright and appear before each QRS and have the same shape. The intervals between the P waves are regular although some variations can occur with respiration.

Sinus Arrhythmia

sinus-arrhythmia

Sinus arrhythmia looks normal except for slight irregularities. A frequent cause of sinus arrhythmia can be rhythm variations caused by respiration.

Sinus Tachycardia

sinus-tachycardia

Sinus tachycardia is a normal sinus rhythm but with a heart rate over 100 bpm. It is a normal response to exercise, excitement and some illnesses.

Sinus Bradycardia

sinus-bradycardia

Sinus bradycardia is a sinus rhythm with a rate of 40-60 bpm.

Atrial fibrillation/flutter (ReelDx) Atrial Fibrillation

afib

Low-amplitude fibrillatory waves without discrete P waves and an irregularly irregular pattern of QRS complexes

Irritable sites in the atria fire very rapidly, between 400-600 bpm. This very rapid pacemaking caused the atria to quiver. The ventricles beat at a slower rate due to the AV node is blocking of some of the atrial impulses.

Atrial Flutter

atrial-flutter

There are two types of atrial flutter. Type I (also called classical or typical) has a rate of 250-350 bpm. Type II (also called non-typical) are faster, ranging from 350-450 bpm. EKG tracings will show tightly spaced waves or saw-tooth waveforms (F-waves).

Atrioventricular block First degree AV block

First Degree AV BLOCK

First-degree heart block is actually a delay rather than a block. It is caused by a conduction delay at the AV node or bundle of His. This means than the PR Interval will be longer than normal (over 0.20 sec.).

  • (PR interval longer than 1 big box 0.20 seconds)

Second degree AV block Type 1 (Wenckebach) and Type 2 (Mobitz)

Type I: Wenckebach block

second-degree-heart-block-type-i

Wenckebach (longer, longer, longer drop now you've got a Wenckebach)

With second-degree heart block, Type I, some impulses are blocked but not all. More P waves can be observed vs QRS Complexes on a tracing. Each successive impulse undergoes a longer delay. After 3 or 4 beats the next impulse is blocked. On an EKG tracing, PR Intervals will lengthen progressively with each beat until a QRS Complex is missing. After this blocked beat, the cycle of lengthening PR Intervals resumes. This heart block is also called a Wenckebach block.

Type II: Mobitz

second-degree-heart-block-type-ii

MOBITZ 2 (some get dropped some get through now you've got mobitz 2)

With Mobitz Type II blocks, the impulse is blocked in the bundle of His. Every few beats there will be a missing beat but the PR Interval will not lengthen.

Third degree AV block

third degree av block

With this block, no atrial impulses are transmitted to the ventricles. As a result, the ventricles generate an escape impulse, which is independent of the atrial beat. In most cases, the atria will beat at 60-100 bpm while the ventricles asynchronously beat at 30-45 bpm.

  • There is no electrical communication between the atria and the ventricles complete AV dissociation. P wave do not match the QRS one for one
Bundle branch block bbb

With this conduction block, either the left or right bundle branch is blocked intermittently or fixed. The QRS complex is wider than normal (> 0.12 sec.). Using a 12 lead EKG, blocks in either the left or right bundle branch may be diagnosed.

  • Look at V1 and V2:
  • Right BBB “R” = Rabbit Ears
  • LBBB broad slurred R in V4 and V6
Paroxysmal supraventricular tachycardia Supraventricular Tachycardia 

svt

A faster than normal heart rate beginning above the heart's two lower chambers in the atria, AV junction or SA node

Wolff-Parkinson-White Syndrome

wolff-parkinson-white-syndrome

This occurs when the impulse travels between the atria and ventricles via an abnormal path, called the bundle of Kent. The impulse, not being delayed by the AV node, can cause the ventricles to contract prematurely. EKG characteristics include a shorter PR Interval, longer QRS complex, and a delta wave.

Multifocal Atrial Tachycardia

multifocal-atrial-tachycardia

When multifocal atrial tachycardia occurs, multiple (non-SA) sites are firing impulses. The P waves will vary in shape and at least three different shapes can be observed. The PR Interval varies. Ventricular rhythm is irregular.

Premature beats  Premature atrial beats

premature-atrial-complex

This occurs when an ectopic sites within the atria fires an impulse before the next impulse from the SA node. If the ectopic site is near the SA node, the P wave will likely have a shape similar to a sinus rhythm. But this P wave will occur earlier than expected.

Premature junctional beats

pjc

Premature junctional complex (PJC) occurs when an irritable site within the AV node fires an impulse before the SA node. This impulse interrupts the sinus rhythm. The QRS complex will be narrow, usually measured at 0.10 sec or less.

Premature ventricular contractions

pvc

Premature ventricular complexes (PVCs) occur when a ventricular site generates an impulse. This happens before the next regular sinus beat. Look for a wide QRS complex, equal or greater than 0.12 sec. The QRS complex shape can be bizarre. The P wave will be absent.

Sick sinus syndrome sick sinus syndrome

Episodes of alternating sinus tachycardia and bradycardia (tachy-brady syndrome), pacemaker placement

Ventricular tachycardia  v tach

A sequence of three PVCs in a row is ventricular tachycardia. The rate will be 120-200 bpm. Ventricular Tachycardia has two variations, monomorphic and polymorphic.

Ventricular Tachycardia Monomorphic

ventricular-tachycardia-monomorphic

Monomorphic ventricular tachycardia occurs when the electrical impulse originates in one of the ventricles. The QRS complex is wide. Rate is above 100 bpm.

Ventricular Tachycardia Polymorphic

ventricular-tachycardia-polymorphic

Polymorphic ventricular tachycardia has QRS complexes that very in shape and size. If a polymorphic ventricular tachycardia has a long QT Interval, it could be Torsade de Pointes.

Ventricular fibrillation  ventricular-fibrillation

Ventricular fibrillation originates in the ventricles and it chaotic. No normal EKG waves are present. No heart rate can be observed. Ventricular fibrillation is an emergency condition requiring immediate action.

Torsades de pointes torsade-de-pointes

Torsade de Pointes is a special form of ventricular tachycardia. The QRS complexes vary in shape and amplitude and appear to wind around the baseline.

Pacemaker Rhythm pacemaker-rhythm

Atrial and ventricular pacing can be seen on the electrocardiogram (ECG) as a pacing stimulus (spike) followed by a P wave or QRS complex, respectively. The ECG has the ability to show normal and abnormal pacemaker function.

Congenital Heart Disease

Atrial septal defect Systolic ejection murmur at 2nd left intercostal space with an early to mid-systolic rumble and fixed splitting of the 2nd heart sound (s2)

Coarctation of aorta Higher blood pressures in the arms than in the legs and pulses are bounding in the arms but decreased in the legs.

Patent ductus arteriosus A continuous "machinery murmur" at the upper left sternal border, treat with indomethacin

  • The ductus arteriosus is a blood vessel which connects the pulmonary artery to the aorta. In utero this allows most of the blood to bypass the lungs.  Treat with indomethacin

** remember the patient got a patent for his machine!

Ventricular septal defect VSD is the most common pathologic murmur in childhood, loud, harsh, holosystolic murmur at the lower left sternal border

  • VSD
  • Overriding aorta
  • Right ventricular outflow obstruction

Heart Failure (ReelDx)

Systolic Left Heart Failure

  • Systolic – S3 (Rapid ventricular filling during early diastole is the mechanism responsible for the S3)
  • Dilated thin-walled weak left ventricle: Often due to CAD or heart attack which causes the muscle to die
  • Dyspnea, PND, orthopnea, rales, crackles, displaced downward and to the left apical impulse
  • Dilated left ventricle and a low ejection fraction < 40%
  • Treat with Ace Inhibitor + βblocker + Loop Diuretic
  • Systolic left heart failure is diagnosed and treated based on class: Class I, II, III and IV and patients can go from controlled class I to poorly controlled and worsening class II, III or IV and back.
  • Acute worsening of heart failure: O2 + Ace + stop βblocker + start nitroglycerine and a double dose of diuretic IV (once stable go back on βblocker and PO loop diuretics)

Diastolic Left Heart Failure

  • Diastolic - S4
  • Hypertrophic thick walled left ventricle with impaired relaxation
  • Increases over 55 years of age, commonly in patients with hypertension
  • Patients will have problems when blood pressures increase, often when patients forget to take their medications
  • Dyspnea and rales with an apical heave or lift
  • Ejection fraction is usually normal
  • Treat with: Ace inhibitor + βblocker or CCB (do not use diuretics in stable chronic diastolic failure)
  • Never use digoxin for diastolic heart failure
  • Acute = same as systolic left heart failure = Ace inhibitor + loop diuretic IV + NTG + O2

Right heart failure (Right ventricle)

  • Cause: Pulmonary HTN – the right heart is unable to easily pump blood into the lungs.  Most common cause of right heart failure is left heart failure.
  • No rales, JVD, and leg edema
  • Diagnose with echo and doppler, Gold Standard is right heart cardiac catheterization
  • Treat the underlying condition

High output cardiac failure:

  • Caused by increased metabolic demand – metabolic demand is higher than the heart can pump at maximum.
    • Hyperthyroidism
    • Severe anemia
    • Beriberi or thiamine deficiency
  • Will have tachycardia at first but once the heart tires it will look like systolic failure because the heart will dilate and weaken
  • Treat like heart failure and acute CHF, treat the underlying condition

  • Best screening test: aldosterone/renin ratio
  • Diagnose with CT or MRI of adrenal glands - shows: adrenal adenoma or hyperplasia

Chronic Kidney Disease
