Rapid and dangerously uncoordinated ventricular contractions is called ventricular fibrillation, or v-fib. During v-fib, the ventricle is not pumping blood to the body, and thus v-fib is known as a lethal dysrhythmia.

It is called a flutter, if it was referring to irregular rapid contractions it would be called tachycardia.

If a rhythm is present it is not an arrhythmia, therefore there is not an arrhythmia in which atrial contractions are rapid but regular

What is PVC of the heart?

Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of your heart's two lower pumping chambers (ventricles). These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a fluttering or a skipped beat in your chest. Premature ventricular contractions are common β€” they occur in many people. They're also called: Premature ventricular complexes Ventricular premature beats Ventricular extrasystoles If you have occasional premature ventricular contractions, but you're otherwise healthy, there's probably no reason for concern, and no need for treatment. If you have frequent premature ventricular contractions or underlying heart disease, you might need treatment.
