16
Q

V tach

A
  • ischemic heart dz
  • Myocardial scar (old MI) –> ectopic electrical focus
  • Hemodynamic compromise
17
Q

Torsades de Pointes

A

two competitive, irritable foci in the ventricular myocardium

  • HypoK
  • HypoMg
  • Hypocalcemia
  • K blockers
  • Congenital long QT syndrome (female)
18
Q

Atrial flutter

A

long AV node refractory period –> stops atrial signal from going to ventricles (V rate slower than A rate)

19
Q

A fib

A

Atria not conducting/contracting w/ any regularity

20
Q

V fib

A

*Cardiac arrest

21
Q

PEA Pulseless Electrical Activity

A

Dying heart generates electrical impulses (but NO PULSE)

22
Q

Asystole

A
  • death

* leads fell off

23
Q

1st degree Heart block

A
  • up vagal tone (atheletes)
  • Meds (antiarrythmics)
  • MI
  • electrolyte disturbance
24
Q

2nd Degree Heart Block type 1 (wenchebach)

A
  • Atheletes

* electrolytes disturbance

25
Q

2nd degree heart block type 2

A
  • Chronic fibrotic dz of conduction system/chronic inflammation (Lyme)
  • lead to syncope / complete heart block
  • need pacemaker
26
Q

3rd degree/ complete heart block

A

Need pacemaker
