Colleen:

 

Digitalis, the prototype inotropic agent in Western pharmacology will

decrease heart rate in patients with atrial fibrillation and possibly

do the same in patients with congestive heart failure. Theoretically

it has no effect on heart rate, resting BP or exercise BP in patients

in normal sinus rhythm. (American College of Sports Medicine)

 

The reason is that BP is a product of cardiac output (heart rate X

stroke volume) and peripheral vascular resistance. With only stroke

volume being effected by the inotropic agent, the other variables

will be intrinsically regulated to maintain homeostasis. In the

absence of this intrinsic regulation, the BP would increase.

 

Further, the Western treatment of hypertension focuses primarily on

reduction of peripheral vascular resistance. All the major catagories

of antihypertensive medications focus on reducing peripheral

resistance rather than on cardiac output. Most focus on vasodilation

(ACE inhibitors, angiotensin receptor antagonists, calcium channel

blockers, and alpha blockers). Others reduce resistance by other

mechanisms (diuretics by reducing total fluid volume). Only beta

blockers focus on cardiac output - and they reduce it, actually a

negative inotropic effect.

 

It also seems that the reductions in BP that occur with exercise

training and weight loss are as a result of reduction of peripheral

resistance, not increases in cardiac output.

 

Therefore the mechanism of lower blood pressure cannot be attributed

to the positive inotropic effect nor can one expect that a positive

inotropic agent will reduce blood pressure...at least not by virtue

of the inotropic effect.

 

Hope that is helpful.

Hi Richard,

 

Why not give CHiNOSIS a try as well, it directly amalgamates hypnotic

principals with the meridian stimulation used in EFT. A free workbook can be

obtained from...

only too happy to answer any questions you may have.
