Non sustained VTach: Tx

A

asymptomatic & no heart dz: no Tx

symptomatic & no heart dz: rate control (BB) or ablation

A

cardioversion w/ sedation if possible

98
Q

Sustained VTach leading to cardiac arrest: Tx

A
  • chest compressions
  • Defibrillation
    –> Epinephrine or Amiodarone
99
Q

Chronic/recurring sustained VTach: Tx

100
Q

Polymorphic ventricular VTach aka…

A

Torsades de Pointe

101
Q

Describe Torsades de Pointe.

A

Shape of contractions from each beat changes as signal begins in different areas of ventricles

Usually a sequalae of Long QT Syndrome

102
Q

Torsades de Pointe: Tx

A
  • Stop any causative agents
  • Fix underlying electrolyte abnormalities
  • IV magnesium sulfate***
  • Temporary pacing
103
Q

What is long QT syndrome?

A

having a QT interval longer than normal

104
Q

What causes acquired long QT syndrome?

A
  • Drugs (some anti infectives, anti psychotics, anti emetics)
  • Electrolyte abnormalities (hypoCa++, hypoMg++, hypoK+)
  • Starvation states (anorexia nervosa)
105
Q

What causes congenital long QT syndrome?

A
  • Genetics
  • > in females
  • First manifestations is 14 years old
  • Should avoid any QT prolonging drugs
  • High risk pts may get ICD, & tx chronically w/ BB
106
Q

Describe VFib.

A

“bag of worms”

  • can lead to sudden cardiac death in mins
  • uncoordinated ventricular contraction
  • each wave on EKG goes w/ a different part of ventricle contracting

A

VFib
Pulseless VTach

108
Q

VFib usually occurs during a…

A

MI

  • epi
  • amiodarone or lidocaine
111

112
Q

What is the spectrum (S/S) of CAD

A

asymptomatic–> stable angina–> unstable angina–> NSTEMI–> STEMI

113
Q

Why do symptoms range so widely for CAD?

A

varying degrees of atherosclerosis (plaque buildup)

114
Q

NOTE

A

CAD is most common heart dz
In the US, someone has a MI every 40secs

115
Q

About how many adults (>/= 20) have CAD?

A

18.2 million

116
Q

Every year, how many Americans have a MI?

Q

Describe Inflammatory response to endothelial cell injury for atherosclerosis

A
  • Injury due to endothelial stress (HTN, smoking, DM)
  • LDL particles leak into the intimal layer, are oxidized
  • Immune response (macrophages) leads to inflammation
  • Leads to a “fatty streak” in the lumen
  • Platelets adhere to the fatty streak & release growth factors
  • Leads to development a plaque that can enlarge & rupture
  • If rupture, more platelets adhere, forming a thrombus, which can occlude the vessel
