Types of Arrhythmia

We've listed the different types of arrhythmias and heart rhythm disorders below:

• Atrial fibrillation

  Atrial fibrillation affects the upper chambers of the heart. Typically the heart beats fast in an irregular, disorganized rhythm.

• Atrial flutter

  Atrial flutter also affects the upper chambers of the heart. The heart beats very fast in a regular rhythm.

• Heart block

  Heart block is a disorder where the electricity does not correctly pass through the electrical pathways of the heart. This results in an irregular heart beat.

• Long QT syndrome

  Long QT syndrome is a disorder where the heart muscle cells take extra time to recover after each heartbeat.

• Sick sinus syndrome

  Sick sinus syndrome occurs when the normal pacemaker of the heart (the sinus node) does not work properly, resulting in irregular heartbeats.

• Supraventricular tachycardia

  Supraventricular tachycardia describes a group of fast heart rhythms that can sometimes occur but are not due to stress or exercise.

• Sudden cardiac arrest

  Sudden cardiac arrest is the sudden, abrupt loss of heart function in a person who may or may not have been diagnosed with heart disease. The electrical rhythm that controls the lower chambers of the heart becomes chaotic, and the heart begins to quiver instead of pumping blood.

• Ventricular tachycardia

  Ventricular tachycardia is a rapid heart rhythm originating in the ventricles of the heart.

• Bradychardia

  Bradychardia is a disorder where your heart beats too slowly.
