Atrial fibrillation may show no symptoms, but there are some
signs and symptoms that may be present; like dizziness,
fatigue, less exercise endurance, weakness, and shortness of
breath.
The American College of Cardiology and the American Heart
Association announced new guidelines in 2014 that modified
the categorization of atrial fibrillation from two to four types:
1. Paroxysmal AFib
Paroxysmal AFib is a kind of AFib that comes and goes. It
starts and ends on its own. The episode might last for a
few seconds to a week. Most episodes of paroxysmal
AFib, on the other hand, resolve within 24 hours.
This type of AFib can be asymptomatic. In addition to
drugs as preventive measures, lifestyle adjustments such
as decreasing caffiene and lowering stress is the first line
of therapy for asymptomatic paroxysmal AFib.
2. Persistent AFib
Persistent AFib can also start on its own. It lasts at least
seven days and may be self-terminating. To terminate an
acute, prolonged AFib episode, medical intervention such
as cardioversion may be required. As a preventative
approach, lifestyle modifications and drugs may be
considered.
3. Long-standing persistent AFib
AFib that can present for at least a year is known as
long-standing persistent AFib.this kindis frequently linked
to structural heart damage.
This type of AFib is challenging for the doctors. Usually,
medications are not successful enough for this case.
Some further invasive options may be require; such as
electrical cardioversion, catheter ablation, or pacemaker
implantation.
4. Permanent AFib
When therapy fails to restore normal heart rate or rhythm,
long-term persistent AFib can become permanent. In this
case, there is no need for further treatment efforts as the
heart is always in an AFib state.
This type can cause more severe symptoms, a worse
quality of life, and a higher chance of a serious cardiac
event.
