Q

What specific finding may be seen on EKG with a small PE? What if it’s a massive PE?

A
  • Small PE: sinus tachycardia

- Massive PE: S1-Q3-(upside-down T)3 = deep S wave in lead I, deep Q wave in lead III, inverted T wave in lead III

Q

What is QTc Interval? When is it considered prolonged for male vs. female?

A

QTcI = depolarization and repolarization corrected for HR

  • Prolonged QTcI for MALES = 0.44+ seconds
  • Prolonged QTcI for FEMALES = 0.46+ seconds

- Digoxin (therapeutic levels, worse if toxicity)

17
Q

What electrolyte abnormality involves shortened QTI, and why is this?

A

Hypercalcemia

- Shortened refractory period

18
Q

A

Shortened QTI

19

A

Shortened QTI

21
Q

What two EKG findings are seen with “Digoxin Effect”?

A
  • Shortened QTI

- Gradual downward curve of ST segment

22
Q

What two EKG findings are seen with Digoxin toxicity?

A
  • WORSE shortened QTI

- Tachydysrhythmia

23
Q

What is the most common tachydysrhythmia associated with Digoxin toxicity?

A

PAT with 2nd degree AV block (2:1)

24
Q
