No. Pulse rate is not necessarily correlated to volume of blood flow. You can have a high pulse rate, and often do, _because_ your heart is weak and failing to pump sufficient blood. Deep breathing actually tends to slow your heart rate down. I don't know what it does to overall blood flow rate. But, I wouldn't be surprised if it directed more blood flow to your capillaries and other areas that don't typically get great blood flow, similar to how your body pumps more blood to your extremities when you are warm. General advice, keep an open mind. When people say things that give you an emotional reaction, ask yourself if it's possible you are getting that reaction because you are afraid they might be right.
