Sinus Rhythms
What is the baseline comparison rhythm?
NSR
What does SVT stand for?
Supraventricular Tachycardia
What rhythm shows a wide QRS and fast rate from ventricles?
V tach
What determines if a rhythms is stable or unstable?
Presence of perfusion and symptoms
HR 45, normal P wave before QRS.
Sinus brady
What rhythm is irregular with breathing related rate variation?
Sinus arrhythmia
Typical HR in SVT?
150-250 bpm
What rhythm has chaotic waves and no organized QRS?
V fib
Signs of unstable tachycardia?
hypotension, chest pain, altered LOC
HR 170, narrow QRS, no visible P wave.
SVT
What is sinus tachycardia?
>100 bpm
What rhythm has no distinct P wave and an irregularly irregular rhythm?
A fib
Which rhythm is life threatening: V tach or V fib?
Both - but V fib is immediately fatal without defibrillation
Stable SVT is treated with what maneuver?
Vagal maneuver
Irregular rhythm, no P wave, narrow QRS.
A fib
What is sinus bradycardia?
<60 bpm
What is the major risk for A Fib?
Stroke
What is the priority tx for V fib?
Defib V-fib
What medication is commonly used for stable SVT and what is a potential side effect that can happen after administration?
Adenosine - can cause asystole
Wide, rounded, fast rhythm with present pulse.
V tach
In sinus rhythms, what must always be present before each QRS complex?
P wave
Why does A Fib increase clot risk?
Blood pool in the atria
Why is V-fib incompatible with life?
Pulseless V-tach is treated the same as which rhythm?
V-fib
Chaotic baseline, no pulse.
V fib
