Propafenone and atenolol are both antiarrhythmic drugs.

But there is an interesting thing. All anti-arrhythmic drugs can cause arrhythmias!

Therefore, clinically, any kind of arrhythmia drug should be used with great caution.

For example, general premature beats, whether premature ventricular or premature atrial fibrillation, do not require special treatment or any anti-arrhythmic drugs as long as the patient does not have structural heart disease.

Drug abuse may lead to more serious consequences!

…

Lu Chen's clinical career was short, and he had not encountered propafenone poisoning.

The drug principle of propafenone in treating arrhythmia is to increase the refractory period of myocardial cells, thereby blocking ectopic cell depolarization and allowing sinus rhythm to take over first.

However, during his internship, Lu Chen encountered a patient suffering from aconitine poisoning.

Aconitine, like propafenone, can inhibit sinus node function.

At that time, the patient had frequent ventricular premature episodes and short bursts of ventricular tachycardia. He did not undergo blood purification treatment, but simply used drug treatment, and his condition improved in the end.

Lu Chen thought for a while and immediately edited a reply.

"Director Fan, if you can stabilize the sinus rhythm and blood pressure, hemoperfusion may have a certain effect."

Fan Zhiping kept staring at the conversation with Lu Chen.

When Lu Chen's message appeared in the dialog box, he looked happy.

This is the first person he has seen today who has definitely said that hemoperfusion is effective.

Fan Zhiping immediately replied: "But the patient's blood pressure is unstable and keeps fluctuating in Hg. And now the electrocardiogram shows fast atrial fibrillation with a heart rate of 130 beats."

"That might not work. We have to solve the arrhythmia problem first." Lu Chen frowned.

"Can electrical cardioversion be performed?" Fan Zhiping sent another message.

Generally, patients with arrhythmia who have hemodynamic instability, that is, low blood pressure, can basically use electrical cardioversion.

"Electrical cardioversion cannot be used in this patient." Lu Chen replied, "The patient's sinus node function is suppressed and there is potential conduction block, which is a contraindication for electrical cardioversion."

The electrical conduction system of the heart is a system with distinct upper and lower levels.

The sinoatrial node sends out electrical impulses, which are then conducted down one level.

The sinoatrial node acts as a commander, controlling all downstream conduction systems.

Once the function of the sinoatrial node is inhibited and there is no commander, the heart's electrical conduction system will be chaotic.

"Then what else can be done?" Fan Zhiping asked doubtfully.

"Take half a dose of atropine quietly first!"

When the message from Lu Chen appeared on Fan Zhiping's phone screen, he looked stunned.

The blue light of the screen accentuated the look of shock on his face.

However, the movements in his hands were not slow and he immediately replied: "Are you sure?"

"Sure!"

To be on the safe side, Lu Chen first asked Fan Zhiping to push half of atropine.

Seeing Lu Chen's exact answer, Fan Zhiping didn't hesitate at all.

He immediately placed a medical order in the computer medical record system - intravenous injection of half a vial of atropine.

"Luo Xin, give half a dose of atropine to the poisoned patient who came just now! I have already given the doctor's order." Fan Zhiping walked out of the doctor's office and came to the nurse's station.

"Roger it!" After Luo Xin agreed, she felt something was wrong, "Director Fan, the patient's heart rate is 130 beats. Are you sure you want to give half a tube of atropine?"

Atropine is a drug that increases heart rate!

In many medical dramas, an emergency case is involved, which is organophosphorus poisoning.

The specific antidote for organophosphorus poisoning is atropine.

At this time, a large amount of atropine needs to be injected intravenously, so there will be various scenarios of concerted efforts to "break off the atropine."

But now, their patient's heart rate is 130 beats.

Still need to give him atropine?

Will the heart rate continue to rise?

Based on her limited knowledge, Luo Xin felt that this was a wrong medical order.

"That's right, half a vial of atropine will be injected intravenously. Do it now!" Fan Zhiping's voice was unmistakable.

Seeing this, Luo Xin could only abide by the doctor's orders.

She came to the ward and took out the medicine on the emergency cart.

Half a vial of atropine was slowly injected intravenously into the girl on the hospital bed.

Fan Zhiping and Luo Xin both stood beside the hospital bed, staring closely at the electrocardiogram monitor beside the bed.

Atropine works quickly.

Just finished the silent push, not even half a minute has passed.

The patient's heart rhythm changes.

On the bedside ECG monitor.

The patient's heart rhythm changed from atrial fibrillation to sinus rhythm (normal heart rhythm)!

The heart rate also dropped sharply from 130 beats just now to 80 beats.

Luo Xin's eyes widened and she saw the patient's heart rhythm changes with her own eyes. This scene was still very shocking.

She stared closely at the EKG monitor, fearful that this was just a blip.

It lasted about a minute.

The patient's heart rate stabilized, basically maintaining 80 beats.

Fan Zhiping immediately stepped forward and asked the patient on the bed.

"Classmate, do you feel better about your panic?"

On the hospital bed, the girl nodded slightly: "I feel better after the injection just now."

Fan Zhiping was also shocked in his heart.

Half a pill of atropine actually solved the problem of arrhythmia!

Until now, he hasn't figured out the rationale for this.

Atropine is obviously a drug that increases heart rate!

Why did the patient's heart rate drop after using it?

"Luo Xin, take care of the patient first, and call me anytime if anything happens."

"good!"

Fan Zhiping immediately walked out of the ward and came to the corridor.

He took out his cell phone and immediately edited a message for Lu Chen with great excitement.

"Professor Lu, you are so amazing!"

If Fan Zhiping could not save face before, now, he shouted out the words "Professor Lu" without any psychological burden.

No matter how old he is, whether he is a student or some other status.

At this moment, Lu Chen was the existence of "Professor" to Fan Zhiping!

When Lu Chen received this message, a smile appeared on his face.

It seems that the patient's arrhythmia problem has been resolved!

Lu Chen continued: "Change a small dose of atropine micropump, maintain the sinus heart rate at about 80 beats, and continue propafenone for five half-lives, which is about one and a half days. Other situations will be dealt with later!"

"Received!" Fan Zhiping replied immediately.

Lu Chen’s words, UU Reading www.uukaｎshu.ｎnet is now the “imperial edict”!

"Luo Xin, use a small dose of atropine micropump to keep the patient's heart rate at 80 beats!" Fan Zhiping took his mobile phone and shouted to Luo Xin in the ward.

"Okay, Director."

Luo Xin also saw how powerful Director Fan was, and now she had no doubts.

She immediately carried out Fan Zhiping's medical advice.

"If there's nothing else, I'll go and get busy first." Lu Chen said.

"Professor Lu, go and do your work, I won't disturb you."

Now Fan Zhiping calls out the three words "Professor Lu" without any embarrassment, but feels particularly smooth!
