Chapter 619: Rescue (Part 2)

Looking at the ECG in his hand, the undulating waveforms seemed like a harbinger of doom.

The incident occurred suddenly, and no one expected such a thing to happen.

The patient was all set to be discharged, the discharge papers had already been prepared, and the recovery was swift.

Who could have foreseen that at such an unimportant moment, such a critical issue would arise?

Ventricular fibrillation!

Now, the cause of the coma had been found: it was ventricular fibrillation.

Ventricular fibrillation, often abbreviated to VF, is one of the common triggers for sudden cardiac arrest and death.

In fact, the heart is a muscle that contracts rhythmically to pump blood...

However, its strength is limited; increase the frequency too much, and the force will inevitably be insufficient, thus naturally very little blood can be pumped out.
