Types of arrhythmias:
The type is based on the speed of the heart rate:
This includes Tachycardia and Bradycardia.
Tachycardia : This refers to a fast heartbeat a resting heart rate grater than 100 beats a minute.
Bradycardia: This refers to slow heartbeat a resting heart rate less than 60 beats a minutes. During exercises the heart works fast to provide the tissues with more oxygen rich blood. During sleep the heart beat is slower.
Tachycardia in the Atria:
Atrial fibrillation is a rapid heart rate cased by chaotic electrical impulses in the atria. These signals result in rapid, uncoordinated weak contraction s of the atria. These improper electrical impulses resulting in bombardment of the AV node, usually resulting in an irregular, rapid rhythm of the ventricles.
It is similar to the atrial fibrillation. The heartbeats are organized and more rhythmic electrical impulses than in the atrial fibrillation. This may also lead to the serious complications such as stroke.
These types of tachycardia originates above the ventricles in the atria or AV node. These might result in palpitation
Wolff Parkinson White syndrome:
In this syndrome there is an extra electrical pathway between the atria and ventricles. This might result in the pathway of the electrical signals to pass between the atria and ventricles without passing through the AV node leading to short circuits and rapid heartbeats.
Tachycardia in the Ventricle.
It is a rapid, regular heart rate that originates with abnormal electrical signals in the ventricles. The rapid heart rate doesn't allow the ventricles to fill and contract efficiently to pump enough blood to the body.
Ventricular fibrillation occurs when rapid, chaotic electrical impulses cause the ventricles to quiver ineffectively instead of pumping necessary blood to the body. This serious problem is fatal if the heart isn't restored to a normal rhythm within minutes.
Tachycardia in the ventricles:
It starts from the abnormal electrical signals in the ventricles.
Long QT syndrome:
It is the heart disorder that carries an increased risk of fast , chaotic heartbeats. These rapid heartbeats caused by changes in the electrical system of the heart that might lead to the fainting .
It is termed as the slow heartbeat.
Sick sinus syndrome:
The sinus node if does not works properly it might leads to both tachycardia and bradycardia. Sick sinus syndrome can also be caused by scarring near the sinus node that's slowing, disrupting or blocking the travel of impulses
A block of your heart's electrical pathways can occur in or near the AV node, which lies on the pathway between your atria and your ventricles. A block can also occur along other pathways to each ventricle.
Although it often feels like a skipped heartbeat, a premature heartbeat is actually an extra beat. Even though you may feel an occasional premature beat, it seldom means you have a more serious problem
