According to the National Institute of Health, ventricular tachycardia is a fast, regular beating of the ventricles that may last for only a few seconds or for much longer. A few beats of ventricular tachycardia often doesn't cause problems. However, episodes that last for more than a few seconds can be dangerous. Ventricular tachycardia can turn into other, more serious arrhythmias, such as ventricular fibrillation.

Based on the passage above, how will prolonged ventricular tachycardia affect blood pressure?

It will increase blood pressure because the ventricles are contracting with more force.
It will increase blood pressure because the ventricles are filling with more blood between beats.
It will decrease blood pressure because there is a longer rest period beats of the ventricles.
It will decrease blood pressure because the ventricles are filling with less blood between beats.

I know it will decrease. The venticles are filling with less blood between beats most likely since the heart is beating faster. (I hope this helps!)

Explanation:

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
