100
This rhythm disturbance is characterized by an irregularly irregular rhythm and loss of organized atrial contraction.
What is Atrial Fibrillation
100
Uterine mechanical compression of this vessel causes reduced venous return to the right ventricle leading to postural hypotension syndrome.
What is the inferior vena cava?
100
What remains the classic tool to describe a patient's functional status?
What is the New York Heart Association class?
100
This condition involving elevated pressure in the pulmonary circulation is one cardiac condition in which pregnancy is contraindicated because of the high maternal mortality risk.
What is pulmonary hypertension
100
Testing of maternal cardiac status is warranted in patients that present with these symptoms.
What is SOB, Chest pain, or palpitations, and a known cardiovascular disease?
200
This is one of the most common atrial arrhythmias in pregnancy 
What is Supraventricular tachycardia?
200
Pregnancy causes a continuous increase in cardiac output and plasma volume and a decreased in maternal SVR due to these hormones
What is Estrogen, Progesterone, and activation of RAAS?
200
These two uncomplicated cardiac conditions are examples of mWHO Class I.
What are small atrial or ventricular septal defects?
200
Peripartum cardiomyopathy is characterized by a left ventricular ejection fraction below this percentage, with onset late in pregnancy or during the first few months postpartum.
What is less than 45%
200
This noninvasive imaging study is commonly used to evaluate cardiac structure and function during pregnancy.
What is echocardiography?
300
This is the most common abnormality seen on an EKG in a pulmonary embolism.
What is Sinus tachycardia?
300
During the postpartum period, blood pressure increases during this time due to fluid shifts
What is day 3-6?
300
Pregnancy is considered contraindicated in this WHO risk class.
What is mWHO Class IV?
300
Dilation of this structure beyond 4 cm is considered a contraindication to pregnancy.
What is aortic root dilation greater than 4 cm?
300
This type of valve prosthesis requires therapeutic anticoagulation during pregnancy and creates important risks for both mother and fetus.
What is a mechanical valve prosthesis?
400
This medication used for uterine contraction can cause arrhythmias and hypotension and should be carefully titrated rather than rapidly administered IV.
What is oxytocin?
400
Maternal hemodynamics generally return to a pre-pregnancy state at this point in time.
What is 3-6 months.
400
ACOG identifies this as the most widely accepted and validated tool for estimating pregnancy risk in women with known cardiovascular disease.
What is modified World Health Organization (mWHO)?
400
Regardless of functional class, pregnancy is contraindicated in certain conditions due to the maternal risk of mortality reaching this percentage.
What is 25-50%
400
This laboratory marker is preferred for serial evaluation of myocardial injury around delivery because it is less affected by labor.
What is troponin?
500
This rhythm proceeds the current tracing above and can be caused by common antiemetics given in pregnancy.
What is prolonged QTc? (Zofran)
500
The increase in cardiac output during pregnancy is primarily caused by increases in these two variables.
What are heart rate and stroke volume?
500
Women in this risk class generally require cardiology follow-up approximately once every trimester.
What is mWHO Class II?
500
This period is particularly dangerous for women with cardiovascular disease because of major fluid and hemodynamic changes.
What is postpartum?
500
These commonly used heart-failure medications are not advised during pregnancy and can be reconsidered postpartum.
What are ACE inhibitors and angiotensin receptor blockers?
