Brief Summary
The purpose of the research is to characterize the effect of labetalol, atenolol, and nifedipine on maternal hemodynamics early in pregnancy. Patients will be given medication based on their hemodynamics and asked to return for a repeat measurement.

Outcome Measures
Primary Outcomes (6)
Systolic blood pressure
Measured in mmHg
Initial assessment of hemodynamic parameters will be measured. A change from baseline will be assessed one week later.
Diastolic blood pressure
Measured in mmHg
Initial assessment of hemodynamic parameters will be measured. A change from baseline will be assessed one week later.
Mean arterial pressure
Measured in mmHg
Initial assessment of hemodynamic parameters will be measured. A change from baseline will be assessed one week later.
Heart rate
Measured in beats per minute
Initial assessment of hemodynamic parameters will be measured. A change from baseline will be assessed one week later.
Cardiac output
Measured in liters per minute
Initial assessment of hemodynamic parameters will be measured. A change from baseline will be assessed one week later.
Systemic vascular resistance
Measured by dynes · sec/cm\^-5
Initial assessment of hemodynamic parameters will be measured. A change from baseline will be assessed one week later.
Study Arms (2)
Beta blockade
Beta blocker (labetalol or atenolol) will be given for a cardiac output \>8 l/min.
Nifedipine
Nifedipine will be given for a mean arterial pressure \>100.
Interventions
Calcium channel blocker
