Pulse

For example, a treadmill with a heart rate detector. The heart rate detectors, or pulse readers, on a treadmill usually has those metal handlebars where you grip it and reads your pulse. Now I am wondering, how is the pulse read? In other words, does the handlebar sense the beats? or is it something else? perhaps maybe electrical currents going throughout the body? and if it is electrical currents, what is it that detects the electrical currents (chip? name of sensor? something else?)?

It is just like an ECG/EKG machine, which reads the tiny voltages generated in the heart and measured at the skin. In this case the metal handlebars are the measuring electrodes. These electrodes pass the signal voltages to an amplifier, usually a single chip known as a operational amplifier. The actual op-amp chip used depends on the manufacturer. The output is shaped to a large pulse, and these pulses are counted for a given time to determine the pulse rate.

I understand hypertension is when the systolic/diastolic reading is outside of the ‘normal’ 135/85 range. I took 3 reading over a 90 min period, at rest, with the 146-154/78-84 ranges. How do I bring down the systolic reading? low-dosage aspirin? exercise? diet? Thanks in advance.

I’ve said it before tonight unless you have been trained to take you BP, especially using a electronic device bought at the drug store or some wrist exercise thingy, Unless You have Calibrated it with a Know Referance most likelthe numbers are screw and off…. That being said I would suggest calibrating whatever your using with the doctors numbers (bring it in) or meet an EMT or Paramedic (firehouse?) and ask if you could get some help calibrating your unit…

Meantime Increase Your >water intake Daily up around 8 liters a day<
begin Looking at your >Daily Sodium Intake you should be between 1200 -1500 MG a day< we were raised being told we needed the sodium and iodine eat eat add it its in there and this is killing us…. Eat the veggies and FRUITS like your supposed to….
start eating Cayenne pepper with your food

I need to conclude whether it is larger before you start a fear ride or after the ride is done. Thanks!

In general, the pulse will be higher after ANY exercise or stress.
