/ Cars / Cadillac. After GMâs bankruptcy in 2009, Cadillac returned with a vengeance and continues to make moves designed to regain the respect of first-tier luxury buyers. Helping its rise is the XT5 crossover, the 7 Series fighting CT6 as well as the ATS-V and CTS-V performance sedans that compete with the best Europe has to offer.
1 A rising heart rate does not cause your blood pressure to increase at the same rate. 2  Even though your heart is beating more times a minute, healthy blood vessels dilate (get larger) to allow more blood to flow through more easily.
Your heart attempts to compensate for this by increasing its output via an increase in heart rate. So, faster heart rate=higher cardiac output=more blood to the brain (a good thing). A rise of less than 20 beats per minute is considered normal (some say 25). You can also measure your blood pressure lying/standing.
