Atrial fibrillation is an irregular and often wrapping heart rate that occurs when two upper chambers of your heart experience chaotic electrical signals. The result is a fast and irregular heart rhythm. The heart rate in atrial fibrillation may range from 100 to 175 BPM

Israel flutter is a type of heart rhythm disorder in which the heart’s upper chambers beat too quickly. In atrial foot of your heart’s upper Chambers be too quickly as causes a hard to be too fast but usually regular rhythm.

Yes

Less than 0.12 (3 sm sq)
Defined as the rhythm of the healthy heart.
Premature ventricle complex (PVC)
Rate:
Dependent on the rate of underlying rhythm and mlnumber of PVC’s
What is the rhythm:
Occasionally irregular, reg if interpolated PVC
Is there a P wave before each QRS:
No P waves associated with PVC
Are the P waves upright and uniform:
P waves of underlying rhythm may be present
What is the length of the PR interval:
PRI not present
Do all the QRS complexes look alike:
N/A
The length of the QRS complex:
>= 0.12 (3 sm sq), usually wide it bizarre
Extra heartbeats that begin in your hearts to lower pumping Chambers. These extra beats disrupt the regular heart rhythm, sometimes causing you to feel a fluttering or skipped beat in your chest.

Rate:
Reg or irreg
What is the rhythm:
Reg or irreg
Is there a P wave before each QRS:
Yes

Yes, until the electrical activity leaves the body
What is the length of the PR interval:
Not concerning or not normal
Do all the QRS complexes look alike:
Yes, until electrical activity leaves the body
The length of the QRS complex:
