Rhythms with irregular R-R ? - Answer✔A-Fib, Sinus Arrhythmia, Wandering Pacemaker, 2nd
degree type 1
Rhythms with no P waves ? - Answer✔SVT, Junctional escape, Idioventricular, Asystole
What does Torsades de pointes look like? - Answer✔It is a type of Polymorphic Tachycardia
How can you tell the difference between a PAC, PVC, PJC? - Answer✔- A PAC is when you have
another full contraction (heartbeat) (P, QRS, T) that starts right after you have already have a
full contraction (heartbeat) (P, QRS, T).
- A PVC, you will have a QRS complex that is greater than 0.12 seconds.
- A PJC is a QRS complex that is 0.12 seconds or less, but does not have a P wave.
Preload - Answer✔Amount of Blood, stretch or pressure in the left ventricles at end diastole
Afterload - Answer✔AKA- Systemic vascular resistance (SVR)
resistance in which the left ventricle must pump to open aortic valve and push blood into
systemic circulation
What is Starlings Law? - Answer✔idiot version :
- increase in blood volume filling heart
- cause increase in contractile force of heart
-Result: increase in stroke volume
Factors of Stroke Volume - Answer✔Preload

Cardiac Contractility
Chronotropic, , Inotropic, Dromotropic explained - Answer✔are different types of cardiac drugs
( can be positive or negative effects)
-Chronotropic - rate
-Inotropic - contractility
-Dromotropic- Velocity of conduction
Refractory Period - 2 phases - Answer✔Absolute - heart muscle completely depolarized (unable
to respond)
Relative- heart muscle partially repolarized (may respond)
P wave represents ? - Answer✔Depolarization of the atria
PR interval represents? - Answer✔Depolarization of the atria and delay of AV junction
QRS complex represents ? - Answer✔Depolarization of the ventricles
ST segment Represents ? - Answer✔period between ventricle depolarization and repolarization
T wave represents? - Answer✔Repolarization of the ventricles
R-R interval represents? - Answer✔time between two ventricle depolarization
What is and what does the delta wave represent - Answer✔its is an upslope into the QRS
associated with a short PR interval.
it represents Wolfe Parkinson white syndrome
what represents the atrial repolarization - Answer✔trick question : its hidden in the QRS
complex
S1 sound (lub) is - Answer✔semilunar valves opening
S2 sound (dub) is - Answer✔AV valves open and semilunar close
most common cause of Left sided Heart failure is ? - Answer✔Myocardial infarction
most common cause of Right sided heart failure is? - Answer✔Left sided heart failure
