Chapter 760: Tower Spirit Electrocardioversion Device, the Teacher Returns!

Gretel practiced hard, practiced hard, practiced hard, and in the end, he was only sure of one thing:

The timing of direct current cardioversion was not something he, a level 7 mage, could control manually.

——The window period is too short. The normal heart rate of a human being is between 60 and 100 beats per minute, that is, once every 0.6 seconds to every 1 second.

In atrial fibrillation, the heartbeat can reach 150 to 500 beats per minute. At its fastest, there is one heartbeat every 0.12 seconds.

During this heartbeat, the waveforms presented by the electrocardiogram are P wave, PR segment, QRS complex with the largest amplitude, ST segment and T wave, and QT interval. Discharge needs to be synchronized with the R wave. This time window may be as short as 4.8 milliseconds!

The reaction speed of the human brain and nerves, I remember the treatment in my previous life said, is 30 milliseconds. Even if you advance to level 7 mage and your mental power and reaction ability are strengthened, you still won't be able to touch this obstacle...

Grete let out a long sigh. He tapped the crystal ball at the center of the mage tower:

"MOSS, play the electrocardiogram again. - Then, every time the R wave peak comes out, change the R wave waveform lines to red."

"Boss, what is R wave?"

Grete gave him an indication, which was the narrowest and highest tip on the electrocardiogram. MOSS was silent for about five seconds and immediately answered:

"Okay, boss."

The light screen flickered again. The wavy electrocardiogram moved forward in a regular pattern. Grete stared at the screen. When the peak of each R wave came out, the line must be changed to red, and then changed back when the peak of the wave was over. very good……

Let’s just say that the tower spirit’s reaction speed is better than that of humans!

In previous lives, there were computers, high-speed computing chips, and automatic surface defibrillators. Before this, doctors wanted to use electric shock defibrillation to save the heart. Basically, it was a matter of betting on probability.

Gretel stood up happily, spread out the blank scroll, and began to copy spells. Well, this one is for an electrocardiogram, and this one is for a modified version of the electric claw. After copying, he spread it out in front of the tower spirit:

"MOSS, can you record these two spells?"

A ray of light fell on the spell scroll, sweeping across it inch by inch from beginning to end. MOSS was flat, and a brisk voice immediately rang out:

"Entry completed, boss."

"Um...can you cast the electrocardiogram spell on me?"

"As long as there is authorization from the boss."

Grete readily gave the authorization. Then, he saw his electrocardiogram. Bang, bang, bang, the waveform is regular and perfect, the heart rate is 55 beats/minute.

The strength of this body that has undergone a major improvement is indeed quite good, and even the heart rate has reached the level of an athlete!

Gretel silently gave himself a thumbs up. Then he continued to give orders to Taling:

"MOSS, according to my electrocardiogram waveform, activate the electric claw spell every time the R wave peak appears, and hit it on the receiving board. Don't hit me! Hit the receiving board!"

"Of course, boss." MOSS still has the same electronic sound without any ups and downs, but the distance between each word and each word is almost doubled:

"The tower spirit will never attack its master..."

Gretel felt that if this tower spirit had a "face", it would definitely show him the unhappiness on its face.

"Okay, MOSS." Grete pretended not to hear the emotion in his voice and gave the order briskly:

"Record the time of each shock and mark it on the electrocardiogram. One, two, three, start!"

"Crack!"

"Crack!"

"Crack!"

Blue-white electric light shone on the dark receiving board.

The corners of Gretel's lips curled up. Talling automatically releases electrocardiogram magic and electrical cardioversion. This treatment mode works!

However, it is obviously impossible for Taring to serve as an automatic defibrillator. If a patient with ventricular fibrillation is dragged to the Mage Tower for rescue, he will probably die on the way there.

The DC cardioverter must be made portable, preferably miniaturized!

"MOSS, I said, remember." Gretel lazily ordered:

“If you want to build a mobile electrocardioversion facility, there are two ways to go:

One is to try to connect two magics together and merge them into one. Let the magic identify the R wave crest, automatically trigger the electric claw, and land on the patient's chest wall at a fixed point;

The second is to make a magic instrument and burn the linkage between [Electrocardiogram] and [Electric Claw] into it. The center of the magic instrument can be a magic crystal or something else. As long as it can intercept a small part of the tower spirit's program, it can control the prop and automatically defibrillate.

Did you write it down? "

"Write it down, boss." MOSS diligently handed over a large stack of draft paper:

"Boss, do you want to start designing now?"

Ah...it's so nice to have a tower spirit to take care of your life. Satisfied, Gretel pulled up a table and sat down, and began to design a new magic:

After the identification and judgment of defibrillable heart rhythm, it is recommended that the user defibrillates quickly and the function can be slowly added. Anyway, the AED machines in the previous life were added slowly...

He lowered his head and scribbled on the paper to make a rough draft, recording ideas for new magic. Well, the first step is to unleash the magic of EKG;

In the second step, the user determines whether defibrillation is needed. If necessary, activates the second magic;

The third step is automatic detection of magic. If the R wave appears, the electric claw will be triggered...

"I'm not a programmer!"

He threw the [Endless Ink Pen] aside and wailed loudly. This kind of [if...then] judgment triggering method looks like writing a computer program!

I am a doctor, not a programmer... How to write conditional trigger magic, and how to connect magic configurations...

Grete tried hard to search his memory, and wrote down one scroll, two scrolls, and three scrolls, but still couldn't get the point. He threw away the pen in frustration and leaned back on his seat:

No more writing!

Go check out the book in the library at Thunder Point tomorrow!

Hey, it would be great if the teacher was here. The teacher could at least throw a stack of reference books to him...

"MOSS... grab a rabbit and a fixed plate to fix the rabbit... I want to do animal experiments..."

Animal experiments can only be done by staying close to Ta Ling, which is simply too troublesome. One day, he will renovate this mage tower and get a sub-center in each laboratory to help him control magic!

Gretel calculated for a long time before he got the current intensity that should be used to perform DC cardioversion on the rabbit. Turning around, the invisible servant was already carrying the rabbit cage and waiting for a long time. The rabbit was chirping and screaming, and the stench filled the cage.

Gretel: "...MOSS, next time I'm calculating, could you please ask the invisible servant to fix the rabbit, shave it off, and disinfect it? Don't even have to clean up the rabbit poop..."

"Okay, boss. Shall I do it now?"

"Forget it, I'll do it..."

Grete quickly fixed the rabbit, prepared the skin, disinfected it, and cast the hypnotic magic. After thinking about it, it was better to deliver electric shock directly from the chest wall instead of opening the chest immediately.

He hooked up the electrocardiogram magic to the rabbit, buried electrodes on the chest wall, and connected the direct current——

One, two, three, press the switch!

Unfortunately, the current is too large, and it seems that the result is not atrial fibrillation...

Grete inhaled and exhaled, lowered his head and quickly calculated the approximate power, adjusted the coil, and turned it on again. Well, it should be okay this time.

Very good, atrial fibrillation!

"MOSS! That spell just now!"

Lightning fell in response. Gretel trembled all over and his hair stood up straight:

! ! !

"...MOSS, the next time you use electric shock for defibrillation, remember to give a warning, count down to three seconds! The electric defibrillation is about to be released, please stay away from the patient, three, two, one!"

MOSS moves too fast! Before he could let go, the electricity went off!

Fortunately, he always wears a full set of defenses, mage armor, cold and heat resistance, and elemental resistance. Otherwise, if the current from this electric claw falls on him, he will be electrocuted!

"Okay, boss!"

Gretel took two hard breaths. Looking at the rabbit again, it seems that the calculated current is still a bit off. Not only was the rabbit not defibrillated successfully, but its vitality became even weaker...

"MOSS, catch another rabbit and bring it up..."

Grete threw two healing spells at the experimental rabbit and stared at the electrocardiogram, watching it recover little by little. After a while, the door of the mage tower opened wide, and Bernard quickly walked in carrying two cages of rabbits and stood quietly to the side.

Grete conducted ten experiments in a row. Although the success rate of the experiment is not high, he at least proved one thing:

Using a certain intensity of current to pass through the rabbit's heart at the right time can restore the heart to normal beating!

Very good. When the teacher comes back, this research should be a good assignment...

Gretel, who was thinking like this, completely forgot that the Lord of Thunder required him to skillfully release attack magic, not to make an electric defibrillator.

"Ah, Bernard, please carry the rabbits down!"

The disappointment on Bernard's face was visible to the naked eye. Gretel didn't even need to ask, he knew that he must have thought that there would be rabbits to eat today. But it's a pity that a bunch of healing spells were released on each rabbit to try to bring them back...

Gretel continued to improve his research with confidence, using 64 rabbits and writing a long paper. A few days after finishing the paper, he received a message from Archmage Carlisle:

"The teacher is back. The regular meeting will be held as usual next Monday, don't forget it!"

yeah!

The teacher is finally back!

There is someone I can ask for advice, and there is a book list I can ask for! He has been browsing left and right in Thunder Horn's library these days, but he has gained nothing!

Early on Monday morning, Gretel was waiting at the teacher's door. At 8:30 in the morning, people attending the meeting began to arrive one after another. When Gretel turned his eyes, his jaw almost dropped:

"Senior Brother Baierbo, Senior Sister Philby! What are you doing?!" Why do you look so smoky? !

"Hey, little Gretel!" The senior brother's big, thick palm slapped Gretel heavily on the shoulder:

"It's a pity that you didn't go this time! Teacher led us to fight a big battle! - Little Gretel, hurry up and advance!"

Yesterday, the final order was 2998...

Just two short...crying loudly...

There are no extra ten chapters! snort!

Thanks to x-on:Crazy Talker for the 100 starting coins reward

I took a look at the history of the development of cardiac defibrillation.

...The earliest record was in 1788, and then theory and practice continued to progress. In 1941, a defibrillator was made to perform internal defibrillation. Synchronized electrical cardioversion was invented in 1961…

The big guys really dare to do anything!
