An arrhythmia, also called an irregular heartbeat occurs when
electrical impulses in the heart don’t work properly. There may be no symptoms,
alternatively, symptoms may include a fluttering in the chest, chest pain,
fainting or dizziness. There are many types of arrhythmias including
1. Premature
atrial contractions,
2. Premature
ventricular contractions (PVCs),
3. Atrial
fibrillation,
4. Atrial
flutter,
5. Paroxysmal
supraventricular tachycardia (PSVT),
6. Accessory
pathway tachycardias,
7. Ventricular
tachycardia,
8. Ventricular
fibrillation,
9. Long QT
syndrome,
10. Bradyarrhythmias
11. Sinus node
dysfunction,
12. AV nodal
reentrant tachycardia.
Ventricular fibrillation happens when the heart’s lower
chambers (ventricles) quiver and cannot contract or pump blood to the body.
This is a medical emergency as VFib is the leading reason behind occurrence of
a cardiac arrest. A victim would require immediate treatment for survival. The
most appropriate treatments being CPR and defibrillation. CPR comprises chest
compressions and rescue breaths. Proper application of the procedure can revive
the life of a cardiac arrest victim. CPR helps to pump blood around the
person’s body when their heart cannot.
Select a certified training site for acquiring training, such
as the AHA certified CPR Tampa in Palm Harbor. Courses for both healthcare and
non-healthcare providers are offered. Here’s information on an ACLS class Palm Harbor:
Advanced
Cardiac Life Support Classes- This American Heart Association
program is for anyone working in an emergency or a critical care type
environment, such as paramedics, critical care nurses, surgeons, emergency
department staff, etc. Become certified at the end of the training classes
after successfully passing a skills test and written exam.
Diagnosis
of Arrhythmias:
Doctors use tests including the following to diagnose an
arrhythmia or find its cause:
Electrocardiogram
(ECG or EKG) - This test records the electrical activity of your ticker.
Holter
Monitor- This is a portable EKG that one will use for 1 to 2 days
where the person will have electrodes taped to their skin.
Stress Test- The goal
of the test is to check how much stress your heart can manage before having a
heart rhythm problem or not getting enough blood flow to the ticker.
Echocardiogram- The test
uses ultrasound to evaluate heart valves and heart muscle.
Other tests include cardiac catheterization, head-up tilt
table test and electrophysiology study.
Treatment
of Arrhythmias:
Electrical
Cardioversion- You might need cardioversion if drugs can't control a
persistent irregular heart rhythm (such as atrial fibrillation). Doctors, after
giving a short-acting anesthesia, deliver an electrical shock to the chest wall
to allow the normal rhythm to restart.
Pacemaker- Pacemaker
sends small electrical impulses to the heart muscle to keep a safe heart rate.
Implantable
Cardioverter Defibrillator (ICD) – It is to treat ventricular tachycardia and
ventricular fibrillation that ICDs are mainly used. The device constantly
tracks the heart rhythm. It delivers an electric shock to the heart muscle when
it detects a very fast, abnormal heart rhythm to cause the heart to beat in a
normal rhythm again. There are several ways the ICD can be used to restore
normal heart rhythm including Anti-tachycardia pacing (ATP), Cardioversion,
Defibrillation and Anti-bradycardia pacing.
Catheter
Ablation- You can take this procedure to be a rewiring to fix an electrical
problem within the ticker where the doctor inserts a catheter through the leg
that delivers high-frequency electrical energy to a small area inside the
ticker that causes the abnormal heart rhythm. What the energy does is it
“disconnects” the pathway of the abnormal rhythm. This procedure is used by
doctors to treat most PSVTs, atrial flutter, atrial fibrillation and some atrial
and ventricular tachycardias.
Heart
Surgery- The Maze procedure is a type of surgery used by doctors to
correct Atrial Fibrillation, during which the surgeon makes a series, or “maze”
of cuts in the ticker’s upper chambers. The main goal of this treatment is to
keep the heart's electrical impulses only on certain pathways.
