What is the difference between postural hypotension and orthostatic hypotension?

Semantics. They mean the same thing. Postural hypotension theoretically could mean any change in posture that induces low blood pressure, but in reality this is only seen when assuming a standing-up position from seated or lying down. Orthostatic hypotension describes the same phenomenon.
Almost same. Positional hypotension refers to decrease in blood pressure with standing. While orthostatic hypotension refers to a defined decrease of BP drop and increase in heart rate with standing from a recumbent position.
Same thing. Two ways of expressing the same issue, a fall in BP when standing.

Can you tell me about orthostatic or postural hypotension?

Orthostatic hypotens. The significance has to do with the problems caused by dropping blood pressure with position change. This can be very problematic for people. See the following wiki for more details: http://en.Wikipedia.Org/wiki/orthostatic_hypotension. Read more...

Separate postural/orthostatic hypotension and tachycardia diagnoses, how does this work?

Need details. It's possible to have both conditions seperately, but they could are more commonly related or part of the same condition. It's likely best to spend some time having a heart rhythm specialist, go over your testing and results, and explaining it to you. A good history and physical examination is also helpful. Good luck.

Separate postural/orthostatic hypotension and tachycardia problems, or just one cause for both?

1 cause. This combination most likely represents pots, postural orthostatic tachycardia syndrome, a form of dysautonomia. The cause remains controversial. There are many potential treatments. Read more...
Not the same. In postural or orthostatic hypotension, BP drops significantly when upright (because among other things, blood pooling). A mechanism the body uses to correct this low BP is to increase the heart rate in an effort to mobilize that pooled blood and increase BP (hydration may help). Abnormal tachycardias are due to electrical abnormalities in your heart and may need to be treated. See your doctor. Read more...

What is the difference between the symptoms of vertigo and symptoms of orthostatic hypotension?

Motion vs. lighthead. Vertigo is defined as "the sensation of motion in the absence of motion." this will lead to the feeling that either you are moving in some way (spinning is common) or your environment is moving. People with orthostatic hypotension do not typically complain of motion, rather they feel as if they are lightheaded or as if they might faint. Read more...
Little. Significant postural hypertension is one of the many causes of dizziness and vertigo on standing due to lack of circulation to the brain in particular cerebellum. The important nature is the postural element. Read more...

Is there a difference bet. Orthostatic hypotension and hypotension?

Low blood pressure. Orthostatis has specifically to do with hypotension related to changing position, usually from supine to standing. Hypotension just means your blood pressure is low and you are symptomatic. That can be from medications, dehydration, irregular heart rhythms, etc. Read more...
Yes. orthostatic hypotension is change in blood pressure due to change in position. A low blood pressure may occur when you stand up. Hypotension is low blood pressure at all times, regardless of position. Read more...

45 minutes tilt test what would be the difference in results between pots and postural hypotension?

Heart rate. In pots there may a drop in BP upon standing but the bigger issue is a fast hr. In neurally mediated syncope (orthostasis ) there is a drop in BP that is associated with either no change in hr (vasodepresor), or a cardioinhibitory response where hr slws. Read more...
