A little doppler heart tour + EKG for those who enjoy hearing the blood flow through the heart. I love seeing those spikey beats while listening to my heart pumping….The doppler sound is almost like you have your ear directly on the throbbing muscle, while every beat is recorded on the monitor for later review.

By the way, doctor, as long as you have such full access to my heart, why not give it a bit of a stress test? A needle in the left ventricle, or a bit of a shock… maybe you even want to give it a little bite to see how it reacts. My heart is yours to play with.

I hope you enjoy this longer video of me playing around, exploring my heart with a doppler and EKG. I added more fun stressors partway through to see the effect I love hearing and feeling my overloaded heart struggling to pump.

“Let’s take a listen to what’s going on in that heart of yours,” he said. “I need to hear how every chamber and valve is working. Using the doppler wand, I can visualize all aspects of your hard-working pump and examine the blood flow.”

As he moved the wand gently around and over the mound of her left breast, the intensity of his gaze made her feel that he could see right through her breastbone to her beating heart. It pounded harder and faster in response, the sound coming through clearly.

He smiled at the effect he had on her. “I see your heart is quite reactive. I can’t wait to test its response to some other stimuli I have in mind.”

What exactly is “redshift”? 

Redshift is defined as: 

a shifttoward longer wavelengths of the spectral lines emitted by a celestial object  that is caused by the object moving away from the earth.

If you can understand that, great! But for those of us who cannot, consider the celestial bodies which make up our night sky. Did you think they were still, adamant, everlasting constants? They may seem to stick around forever, but…

Boy, you were wrong. I’ll have you know that stars are born and, at some point, they die. They move, they change. Have you heard about variable stars? Stars undergo changes, sometimes in their luminosity. (We are, indeed, made of the same stuff as stars).

So, stars move. All celestial bodies do, actually. You might have heard about some mysterious, elusive thing called dark energy. Dark energy is thought to be the force that causes the universe to expand at a growing rate. If it is proven to exist, dark energy will be able to explain why redshift occurs.

Maybe you can understand redshift by studying a visual:

These are spectral lines from an object. What do you notice is different in the unshifted, “normal” emission lines from the redshifted and blueshifted lines?

The redshifted line is observed as if everything is “shifted” a bit to the right– towards the red end of the spectrum; whereas the blueshifted line is moved to the left towards the bluer end of the spectrum.

Imagine if you were standing here on earth and some many lightyears away, a hypothetical “alien” was standing on their planet. With this image in mind, consider a galaxy in between the two of you that is moving towards the alien. You would then observe redshift (stretched out wavelength) and the alien would observe blueshift (shortened wavelength). 

Here,Symmetry Magazine explains redshift in their “Explain it in 60 seconds” series. 

A simple, everyday example of this concept can be observed if you stand in front of a road. As a car (one without a silencer) drives by, the pitch you observe changes. This is known as the Doppler effect. Watch this quick youtube video titled “Example of Dopper Shift using car horn”: 

(You may not be able to view it from the dashboard, only by opening this post on the actual blog page. You can watch the video by clicking this link). 

Notice how as the car drives past the camera man, the sound changes drastically.

Understanding redshift is important to scientists, especially astronomers and astrophysicists. They must account for this observable difference to make the right conclusions. Redshift is one the concepts which helped scientists determine that celestial bodies are actually moving further away from us at an accelerating rate.

Check out my cardiophile shirt. I did it in tie-dye because I will be wearing it to concerts. I prefer my tie-dyes in the red-orange-yellow spectrum, but because I will be wearing this to metal concerts, not just jam concerts, I figured red-orange-yellow would be too bright, too conspicuous, and unbefitting. I’ll be wearing this for the first time August 10th in Hershey park. If anyone lives on the way or in the area, and wants to hang out, let me know. I would love to have a reason to leave here a couple or few days early for the purpose of spending more than just an afternoon and evening after having driven for over six hours. Please, give me a reason to spend more time. I could always go to the next day’s show, but two consecutive concert days is easier said than done. Gone Phishing.

                            ————–STETH MEET————–

I received my Phish ticket in the mail yesterday. I decided on leaving a day early, August 9. I would love to have a steth meet. Let’s hang out. We’ll have a grand ole time. I’m getting a room right down the road from Hershey Park. We can steth, chat, eat, drink, steth, chat, eat, drink, fun fun fun. I’ll have plenty to drink, but if you want something special, let me know. I’ll be staying next to a brew pub, so if nobody shows up, I know where I’ll be that evening. I’m bringing all my steths, my doppler, my bp cuff, and my scrubs even if nobody replies, because, perhaps (because of my cardiophile shirt), I’ll be approached by somebody with cardiophilic tendencies, or just somebody who is playfully curious. Wouldn’t that be a crazy stroke of fortune or luck?

Me and my doppler a few minutes after a workout. He is still chugging. Obviously I didn’t workout in this shirt; it’s for dramatic effect. Beautiful Sundays call for marinated butterflied lamb leg on the grill day, and also doing some heart stuff before cracking my first drink, and before company arrives.

Giving myself a doppler exam, but wishing it were an echocardiogram.

With a stethoscope, I feel it to be an examination of the heart. With a steth, you pick up the head piece, a lot or ever so slightly, and move it to another location. With a doppler, I feel it to be an exploration of the heart. With a doppler, the probe’s location and angle can be slowly and meticulously moved to generate different sounds, SO many different sounds. Yes, with the steth, the heart sounds different depending on the exact location you are listening to, slightly different to very different, all erotic and all beautiful; but with the doppler, it is just, well, a whole different experience, at least to me. I like the sound of the steth much better, but there is just something about that doppler. With a doppler, I feel that there is just more going on, a more sensory experience and adventure. I also love the way the probe looks when being held or manipulated, not that I don’t love the way a steth looks when being held or manipulated, but once again, there is just something about that probe. And with a doppler, you get to smear, rub, and massage gel all over the chest. It’s a fun, pleasurable, and erotic prelude to bliss.

15 pull-ups should make my heart pump harder. The two pushes I did made my heart pause for a good moment, and then pump extremely forcefully right after, insofar as me feeling every slamming beat–yea, it was slamming. I felt a little light-headed. I haven’t used my doppler in quite a while. I forgot just how much fun it is.
