- Each small box is 0.04 seconds
Reading an ECG Strip - Each large box is 0.20 seconds
- 30 large boxes = 6 seconds

- early electrical impulse initiated
by neural tissue in the atria


- Causes: stimulants, strong
Premature Atrial
emotion, smoking tobacco,
Contraction
caffeine


- Intervention: check electrolytes,
lifestyle changes

- HR < 60 bpm
- Rhythm: regular


- Risk Factors: hypoxia, medications (beta-blockers),
lyme disease, hypothyroid, hypothermia
Sinus Bradycardia

- Symptoms: asymptomatic, syncope, low BP, SOB,
dizziness, confusion


- Treatment: Atropine

, - HR >100 bpm
- Rhythm: regular


- Risk Factors: anemia, hypoxia, hyperthyroid, drugs

Sinus Tachycardia
- Symptoms: asymptomatic, SOB, chest pain


- Treatment: beta-blockers (anything ending in -lol),
calcium channel blockers (diltiazem, nifedepine),
change in lifestyle

** RHYTHM MUST BE REGULAR***


- Regular= normal sinus, sinus tachy, sinus brady


- Six Second Method: count number of QRS complexes
in a 6 second strip then multiply by 10

Estimating HR on ECG
- Rule of 300: Find QRS interval hitting exactly a vertical
line then go 300 -> 150 -> 100 -> 75 until next interval


- 1500 method: Count large boxes between R-waves
until the next wave going 5 -> 10 -> 15->..... Then do
1500/x; if you land on a small box count by ones; if you
get a decimal, round up (ex. 1500/19= 78.5 -> 79)
