What are the different types of abnormal heart rhythms?

The most common types of abnormal heart rhythms are:

• Tachycardia. Tachycardia means that your heart is beating too fast.
• Atrial fibrillation. This disorganized heart rhythm occurs in the upper chambers of the heart.
• Atrial flutter.
• Bradycardia.
• Ventricular fibrillation.
• Premature contractions.

What are the 2 abnormal heart rhythms?

Supraventricular tachycardia is a broad term that includes arrhythmias that start above the lower heart chambers (ventricles). Supraventricular tachycardia causes episodes of a pounding heartbeat (palpitations) that begin and end abruptly. Ventricular fibrillation.

Is sinus a rhythm?

Sinus rhythm is the name given to the normal rhythm of the heart where electrical stimuli are initiated in the SA node, and are then conducted through the AV node and bundle of His, bundle branches and Purkinje fibres. Depolarisation and repolarisation of the atria and ventricles show up as 3 distinct waves on ECG.

What is the difference between flutter and fibrillation?

In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles, so you may have four atrial beats to every one ventricular beat.

Can a flutter be irregular?

In people with atrial flutter, the pulse is usually rapid and can be regular or irregular. The reduced pumping ability of the heart may cause weakness, faintness, and shortness of breath.

When I take a deep breath my heart beats faster?

A sinus arrhythmia is an irregular heartbeat that’s either too fast or too slow. One type of sinus arrhythmia, called respiratory sinus arrhythmia, is when the heartbeat changes pace when you inhale and exhale. In other words, your heartbeat cycles with your breath. When you breathe in, your heart rate increases.
