Atrial Fibrillation

Atrial fibrillation

Atrial fibrillation

Among the topics in the science subject Biology, one of the highly discussed ones includes that of Atrial Fibrillation (Af or Afib).  During this syndrome, the top chambers of the heart (atria)would tremble in an irregular manner in place of beating properly which would help in transporting blood into the ventricles.

Changes during  Afib

 It is a known fact that the heart contracts and expands during a regular beat whereas, during Afib, the heart’s upper chamber would beat irregularly (tremble) in place of beating in the right manner so as to transport blood into the ventricles.   A stroke happens when a clot breaks off, enters the bloodstream and attaches to the artery that connects to the brain. This heart arrhythmia is found among at least 15-20 per cent of people. The only reason why patients with this condition are supported with blood thinners is due to the sole risk of clots. Most people are unaware of the serious after effects of this condition despite this disease if untreated would double the possibility of heart failure deaths and even connected to the 5 fold amplified possibility for stroke.

Symptoms of Afib

There are cases where certain people having this disease would not show any signs of symptoms about the same until a physical examination is done to detect the same.  Mostly, the rest of others would be experiencing the below symptoms:

  • Dizziness
  • Weakness
  • Fatigue in general
  • Heartbeat being and rapid and irregular
  • Chest thumping
  • Anxiety and breath shortening
  • Confusion or faintness
  • Sweating

Are there different types of Afib?

The medical practitioners have classified the Afib problems in the following names:

Long-standing:  This is when the irregular pattern of heart continues consistently and extends to above 12 months.

Permanent:  This occurs when the condition continues for an indefinite period and where the patient and doctor has decided to stop more treatments to bring back the real rhythm.

Paroxysmal:   This happens when the normal rhythm of the heart returns back by itself with intervention within 7 starting days.

Persistent:  This condition exists where the improper rhythm would continue or persist above 7 days and requires some type of treatment to come back to normal rhythm.

Nonvalvular:  This condition is not initiated by a heart valve issue.

In the due course, paroxysmal fibrillation might turn into a more frequent one and last longer resulting in a permanent Afib.

From the above discussion, you would have realized as to how important it is for the patients who are suspicious of having a disorder like this one to undergo a physical checkup so that the disease could be spotted early on and stop the condition from worsening.
