Exercise….Again… how do you think she went this time? (Read to the end (or skip) it’s worth it)

So after last time I was told that my heart probably freaked out as I was failing at normal human needs like food and sleep. So better equipped I went out today to try again and slow.

Just a walk… maybe a preset “hike” on the treadmill… HRM linked to see the rate easy. Ecg - in case a decent trace was obtained. Stemoscope taped to my chest - a hybrid erbs spot which actually got good sound despite movement. I felt like a lab rat but was ready to go.

Choose a trek. One looks easy… but didn’t check the stats. Instant 10 grade incline. It’s ok. We’re walking at 3km/h. Easy pace. Listening to may heart in my ears. The sound is good. I’m surprised. I can hear her picking up speed and my breathing getting faster and deeper. But I feel good.

At some point I jump off the treadmill to check the ecg and the sound come recovery time. You will hear her drop. That is not the recovery. She needs a bit more pushing. I increase the speed as my RPE is comfortable. The HRM registers in the 170s and not pushing further. I still feel fine and it’s been about 20 mins. I know I said I wouldn’t run and would take it easy. But I was feeling ok. So I reduce the incline to 0 and crank up the speed. This is the point where the recording cuts out as you can just hear my feet pounding and not my heart. Little by little I increase the speed until we hit 188. She then drops to 182 and keeps climbing and dropping between the numbers. I decide to push a bit more. We haven’t hit 190 in 5 years to that was the goal. Pushing into a sprint, it takes her about a min to realise what’s going on. I’m watching the rate on the screen 186, 189, 192. I jump off, heartbeat pounding as fast as I’ve ever heard her. I catch my breath for a few seconds and realise I should be screen recording my ecg. She’s slowed down a bit by this point but you can see she really seems to like beating in the 140s. 😂

This time I felt fine. No dizziness. A bit quicker recovery from the 180s - 190s. 🥰

time to wire up

A compilation of VT runs that I got while applying pressure. Heavy pressure on the apex+breath play seems to cause some unbelievable results!

The VT runs last up to 5 seconds long, and it was amazing to see on the ECG my heart just quivering in my chest for that long!

Anyone want to come and get wired up

My hands are full ...

... Someone want to help me with these leads?

Part 5

_______________________________

"Keiran... Honey... Keiran!" Gasps Austin as his boyfriend falls still and slumps against his side.

Austin swiftly lays Keiran back flat on the examination bed. The boy's smooth chest flutters as he takes irregular, shallow breaths while a crackling sound escapes his open mouth - fluid filling his lungs. Austin hurridly pulls a monitor over to the bed, grabbing a packet of electrodes from the shelf underneath. While his other hand roughly takes Keiran's chin, Austin's fingers pressing into the boy's cheeks as he holds his head tilted back. Tearing open the packet with his teeth, he takes ten items and begins placing them across Keiran's lean torso. Six electrodes form a slight curve around his left pectoral as Austin presses them onto the boy's pale, clammy skin. The last 4 are placed on his wrists and ankles.

"Keep breathing for me baby, you'll be alright" Utters Austin as he caresses Keiran's chest while attaching wires to the electrodes dotted across the boy's exposed body.

Austin attaches the bunch of wires to the monitor and watches it flash to life, displaying a bradycardic sinus rythm at 40 bpm. He intensely glares at the monitor with concern while placing a pulse oximeter on Keiran's finger. Another number appears on the monitor, showing the boy's oxygen saturation at 84% and falling.

"Keiran, darling focus, keep breathing. You can do it." Encourages Austin, his voice shakey and quiet as he harshly rubs Keiran's sternum with boney knuckles while replacing the oxygen mask over his face.

Austin briefly glances back at the monitor as it alerts, Keiran's oxygen saturation has fallen to 80% and his heart is beating irregularly.

So we got a new toy today….😝 can you tell she’s excited? Or is that just how fast she normally beats these days?

Any tips for lead placement appreciated. For life of me imma struggling to get a T wave to be visible.

Super Weird

Very weird heartbeat with heavy pressure. The massive spike at 0:24 accompanied by a loud heartbeat is interesting, does anyone know what that is?

Finally figured out what the little connector on the side of the MP5 labeled ECG Defib out is for. It literally means that it outputs an analog ECG signal of whatever the monitor is detecting on its ECG input. It’s meant so that you can connect a defibrillator or other equipment to that output and not have to put multiple sets of electrodes on the patient. I just used my mini oscilloscope to show what that looks like. Interestingly it detects the ECG in milivolts but it will output on a ratio of 0.25 to 4 volts per milivolt. The connector is just a regular 1/4in TRS connector used for audio. Sleeve is ground, ring is ECG out, and Tip is ECG out/ marker input. I can also show what the marker input looks like. Let me know if you guys are interested but I could actually build a circuit that would beep every time the voltage goes above a certain threshold using this analog output. I also have yet to find something to connect to the nurse call relay. Interestingly the MP2 also has ECG output but it’s a 6 pin mini DIN connector that I don’t have anything that will fit. I also think I found out why Philips has their monitor support tool software locked down so hard. It allows you to do just about anything with the monitor so you can technically activate software options that cost extra. My MP5 is the base model software except it has the entire clinical applications library unlocked. Hardware wise it has highest option for rear I/O but it has the standard option for measurements. My MP2 has the highest option for measurements with, ECG/Resp (up to 6 leads), SPO2 (with Masimo’s fast SPO2), NBP, temperature, and Press. Press is short for pressure and it’s also know as IBP (Invasive Blood Pressure) it takes an input from a pressure transducer (Which is just an electrical component called a Wheatstone bridge, it’s 4 resistors connected together forming a diamond shape and when pressure is applied and voltage runs through the resistors the voltage will change depending on how much pressure there is) unfortunately to use IBP you need an arterial line which I’m not stupid enough to try to preform myself.

I used the function generator on the mini oscilloscope to output a square wave at 10Hz and this is the result on the ECG waveform.

Christmas Cheer...

So my 3-lead Bluetooth ECG arrived. And when I split-screen its companion app with my Stemoscope, turns out I can just screen record the video and audio in perfect synchronicity. Fun times! I tried to get some PVC's out of him here but he was having none of it.
