ANATOMY

Detailed explanation-1: -When your blood pressure drops, your heart rate increases and the blood vessels in other parts of the body constrict (narrow) to help maintain blood pressure.

Detailed explanation-2: -Low blood pressure with a high heart rate is common and can be caused by various factors. These include vasovagal syncope, atrial fibrillation, weakening of heart muscles, and certain medications, among others. If you think that your symptoms may be due to low blood pressure with a high heart rate, see your doctor.

Detailed explanation-3: -When the heart beats too fast, it may not pump enough blood to the rest of the body. As a result, the organs and tissues may not get enough oxygen. In general, tachycardia may lead to the following signs and symptoms: Sensation of a racing, pounding heartbeat or flopping in the chest (palpitations)

Detailed explanation-4: -Yes. For the same reason dehydration can cause low blood pressure, it can also cause heart palpitations. Palpitations are the feeling of a pounding, fast-beating or fluttering heart. When blood volume is decreased, the heart has to beat faster to try to continue to deliver oxygen to your organs.
