1. DESCRIPTION

Have you ever wanted to watch your heartbeat as it is occurring? I have found a way using a finger pulse oxymeter - Model C20 Oxywatch for $39 at CVS. The device is manufactured by Beijing Choice Electronic Tech Co., and sold by ChoiceMMedusa, LLC. Various models are available at major drug stores everywhere.

My unit says "PULSE OXYMETER", whereas in the photo above, it says "ChoiceMMed". It is otherwise identical, except that mine has a "pulse bar" with the SAME height as the "9" next to it. This unit does not.

The device displays pulse rate in BPM, and blood oxygenation % saturation level. But what I am interested in here, is the fact that the "pulsating pulse bar", shown here on the left, reads your relative BP, in real time. It is not calibrated, so you do not get a BP number. What it CAN tell you - is whether or not you have atrial fibrillation, and the relative severity.

The 4 blue bars shown below are meant to represent the blue pulse bar on the far left shown in the photo above. They represent RELATIVE BP.
.

I find that lying in bed at night is a good time to "watch" my BP. It gives me a great "feel" for the jitteriness of my heart.

I think that one of these devices might be used as a "bio-feedback device". Is it possible to control pulse rate and rhythm, simply by intensely watching your actual pulse pressure in real time? Perhaps with a much larger bouncing blue bar display, or a custom large display?

With diltiazem

During a normal heartbeat, the heart beat is determined by "sinus rhythm". The pulse is strong, and falls back linearly to the diastolic level.

This is what my pulse looks like when I TAKE diltiazem 360 ER.

Without diltiazem

When A-fib is present, the BP does not drop linearly, but instead extra premature pulses occur. This results in a higher overall BP, because the normal low DP is not achieved.

This is what my pulse looks like when I do NOT take diltiazem 360 ER.

The numbers assigned by me are arbitrary, and are selected for the sake of example, and ease of calculation.

My average pulse rate is 60 BPM. (1,000 milliseconds)

My average A-Fib pulse rate is 80 BPM. (750 milliseconds)

Note that at t6, we see an extra, unwanted, premature beat, due to atrial fibrillation (shown in red). This results in a high diastolic BP, as well as a higher average BP.
In my experience, diltiazem seems to work perfectly for suppressing my A-Fib.

Note:
Modern medicine tells us that normal PR varies from 60 to 100 BPM. I have chosen 60 BPM here, because it is near my actual BP, and lends itself well to this discussion.

4. Two Types of A-Fib, + mixed

Sinus Rhythm Beat - perfect rhythm output

1. Hyper Beat - a successive beat occurs prematurely, before it it would occur, if sinus rhythm were present

2. Hypo-beat - a successive beat that occurs later, than it would occur, if sinus rhythm were present

3. Mixed beat - both hyper and hypo beats occur

Three types of A-Fib
