In relation to cardiovascular terms, when your heart is fibrillating, it basically means that it is contracting uncontrollably. The Purkinje fibers would have something to do with it.

What will happen if electricity travels though you?

Current will travel through you if it has a way of creating a circuit. The current can contract your muscles, causing you to be unable to let go. It can also fibrillate your heart. Alternating current (like in your house), will fibrillate your heart if the current is strong enough. Direct current has a tendency to stop your heart. The heart can then start again at a normal pace. That's a pretty short version, but that's somewhat what will happen.


When the atria contract ahead of time is called?

When the atria contract ahead of time, it is referred to as atrial fibrillation. This is a type of irregular heart rhythm where the atria quiver or fibrillate instead of contracting properly. It can lead to symptoms like palpitations, shortness of breath, and an increased risk of blood clots.


How do you make your heart beat 400 times a minute?

You can't. The atrial cells, which control your heart rate, cannot fire that quickly. Even if they could, the atrioventricular node, which propagates the electrical impulse from the atria to the ventricles, does not allow the impulses to move through that quickly. There are some conditions, such as Wolff-Parkinson-White syndrome, in which there are bypass tracts around the AV node, that allow electrical activity directly down into the ventricle. In these conditions, the heart rate can approach 200 bpm - much higher than that, the ventricles begin to fibrillate, which is lethal.


Which one can kill a person between high current or high voltage?

If you think as your body as a complex resistance (you can think of it as a bag of electrolytes!), then the higher the voltage across your body, the higher the resulting current through your body. And it only takes a fraction of an ampere to cause your heart to fibrillate. So, although it is the current that does the damage, it is the voltage that causes the current to flow. Fewer people survive the effects of a high-voltage shock, as the energy levels cause massive burning and tissue damage, even if the heart is unaffected.


What happens if there is not enough salt in the human body?

You can die. Cardiac, as well as other muscles function off of a sodium potassium pump. Lack of sodium in your body throws this pump out of wack and can cause your heart to fibrillate (quiver) and not pump blood. You most commonly hear of this with people doing stupid stunts involving drinking large amoutns of water. Most everybody in developed countries do not need to add salt to his or her diet, regular food consumption is enough.
