   Chapter 286 Exchange Intermediate Cards!

   So the question is, how to judge whether this P wave is interfering?

  Lu Chen thought of the "Eintophan" triangle.

  The electrocardiogram was invented by Professor "Eintofen". He named the recorded electrocardiogram waves as PQRST waves, and this naming method is still used today.

   Through the principle of "Eintophan" triangle, we can judge whether the P wave is interference or not!

   "It's time for it to come out and clean up the scene!" Lu Chen thought to himself.

   After going through the "Eintophan" triangle model, Lu Chen came to a conclusion.

  This second picture is really disturbing!

   It is precisely because of the existence of interference that these little ps appear.

   Among them, lead III is absent, indicating that the interference comes from the left upper extremity.

  So, how to troubleshoot interference is also an important part of the ECG!

  Because it is very easy to be disturbed when doing an electrocardiogram, and sometimes the interference is so perfect, then the "Eintophan" triangle will show its importance at this time!

   After Lu Chen used the "Eintophan" triangle to clean up these little p's, things became very simple!

   The global heart rhythm is also a junctional escape rhythm.

   From the overall macroscopic point of view, the three ECGs are consistent with the diagnosis of junctional escape rhythm.

   When Lu Chen focused his eyes on the individual lead II again, he found that the lead interval was fixed.

   He immediately thought of a diagnosis - complete junctional rhythm!

  Repetitive beat, also known as repetitive heart rhythm, refers to the fact that after the excitation from a certain cardiac chamber depolarizes the cardiac chamber, the excitation is conducted to excite the opposite cardiac chamber.

   At the same time, the conduction direction of the excitation may suddenly turn back and conduct in the opposite direction, and it is an electrocardiographic phenomenon in which the cardiac chamber from which the original excitation originated is re-excited.

  …

  Lu Chen also discovered something more interesting.

   In this electrocardiogram, the combined rhythm interval composed of sinus rhythm and atrial rhythm is exactly the same as the rhythm interval between sinus rhythm and atrial rhythm after serum potassium recovery, both of which are 540ms!

   What does this mean?

   This further shows that the pair of regular pairs with an inverse P in the middle is not a doublet of atrial early, but a junctional repeated beat more reasonable.

   In addition, comparing the electrocardiogram before and after the recovery of serum potassium, the P wave in lead II is consistent with this P wave, both positive and negative, so this electrocardiogram still has escape beats - captured heart rhythm!

  Analysis up to now, this second ECG is about to come out.

   Its final answer is, junctional escape rhythm + complete junctional repeated beat doublet rhythm + escape beat - captured rhythm + atrial premature beat with aberrations.

  …

   When Lu Chen sent the final diagnosis of the second electrocardiogram to the group, everyone in the group was amazed and at the same time admired Lu Chen.

   Who would have thought that some of the P waves and inverse P in this electrocardiogram are interference? !

   This disturbed waveform looks no different from a normal P wave.

   "After applying the "Eintophan" triangle, we can remove these distractions."

  Lu Chen re-edited the ECG in the group, and marked all the interference waveforms, so that everyone could see at a glance.

   After removing the interference wave, this electrocardiogram is still difficult to interpret, but it is not an unsolvable graph!

   Fan Zhiping was in his rental house and was amazed when he saw Lu Chen's answer.

   Really deserves to be "Professor Lu"!

   The interference waveform that no one thought of, was thought of by Lu Chen!

   After getting the diagnosis, everyone in the group started to have rainbow farts.

   "As soon as Professor Lu made his move, he knew if there was any..."

   "Professor Lu, the director asked me why I was kneeling and looking at my phone."

   "Professor Lu Chen is still awesome!"

  …

   At this time, Lu Chen's system panel also kept popping up prompts.

   "Congratulations, +1 for the thank you from Fan Zhiping!"

   "Congratulations, +1 for receiving thanks from He Xi!"

   "Congratulations, +1 for the thank you from Li Jiaxin!"

  “…”

   In just a few minutes, Lu Chen's thanks value skyrocketed again, directly breaking the 300 mark!

   It was eleven o'clock in the evening, but he didn't feel sleepy at all.

With a thought of   , he summoned the system mall.

   "Exchange for an ECG Advanced Skill Card!"

Ding!

   "Congratulations, get the ECG Skill Card (Intermediate)."

  The skill card for the advanced level of ECG not only contains higher-level ECG-related knowledge, but also contains electrophysiological knowledge.

  Lu Chen felt his brain heat up, as if countless knowledge poured into his mind.

   However, these knowledge are temporarily closed, and Lu Chen needs to spend time reading books to comprehend.

   "Great!" Lu Chen was overjoyed.

After    exchanged this intermediate skill card, Lu Chen had a little more confidence in the third round of the test the day after tomorrow.

  Otherwise, with his current ability, it is almost impossible to break through the provincial competition and enter the national competition!

   It's already night, and the rest of the dormitory has already slept.

  Lu Chen resisted the urge to get up and read a book, slowly closed his eyes, and began to fall asleep...

  …

   was speechless all night.

the next day.

   After Lu Chen got up to wash up, he asked Teacher Li Yao for leave. The reason was naturally to prepare for the third round of the exam.

  Li Yao received a call from Lu Chen.

   "Okay, hand over the patients you take care of to Sun Guoguo. In this electrocardiogram competition, you have already achieved a lot. Next, do your best and don't force yourself too much."

   "Well, thank you teacher."

  Lu Chen hung up the phone and first went to the eighth district in his heart to hand over his patient to Sun Guoguo.

   Everyone in the eight districts in their hearts also knew that Lu Chen was going to participate in the third round of the competition tomorrow afternoon.

   "Junior Brother, come on!" Sun Guoguo smiled and said to Lu Chen.

   "Lu Chen, when you enter the national competition, then I can brag with my classmates!" Fatty Cheng approached Lu Chen.

Jiang Qingyan and Ke Yue on the side of    also cheered Lu Chen up.

   However, having said that, everyone didn't have much hope for Lu Chen's third round result!

   After all, Lu Chen was the ninth place in the second round, and the probability of breaking through to the top three was pitifully small.

   And now the top three people are all well-known doctors in Jinghua's electrophysiology field, and Lu Chen is just a first-year graduate student.

  …

   After leaving the eight districts in his heart, Lu Chen came to the teaching building, found a free classroom, and started his own way of studying electrophysiology.

   With the super-high comprehension ability endowed by the ECG Advanced Skill Card, Lu Chen found that the electrophysiological knowledge that he had been difficult to understand before has now become easy to understand.

  Many problems that I didn’t understand before are now solved!

   However, the third round of exams will be held at 2pm tomorrow.

   In less than a day and a half, Lu Chen needs to give full play to the advantages of the intermediate skill card to improve his electrophysiology knowledge!

   Lu Chen spent the whole day studying electrophysiology.

   Three o'clock in the afternoon the next day.

   The third round of the provincial competition of the Huaxia ECG Contest has officially started!
