HEART RHYTHM DISORDERS
A problem with the rhythm, or arrhythmia, is a problem with the electric system that makes the heart beat. There are two main categories of problems: stimulation disorders and conduction disorders.
The electrical system can be overexcited.The extrasystoles are supplementary heartbeats, either extras or premature, or before their time, pulses. The extrasystoles may be a consequence of an overexcited system at the atrium and/or ventricle levels.

Breathing in make the lungs expand but the heart also calls for blood via the large veins. This increase in blood volume accelerates the orchestra conductor so that the heart works faster.

Some arrhythmias may manifest themselves in a slower rhythm than usual. A heart rate slower than 60 beats per minute is called “bradycardia”

Some arrhythmias can be expressed by more rapid beats than normally. A heart beat higher than 100 per minute is called tachycardia.
Inappropriate tachycardia affects more than 1% of the population. However, it is not considered an arrhythmia, but is rather a condition where the heart rate at rest is faster than normal and where there is an inappropriate acceleration of the heart rate when a minimal effort is done.
SUPRAVENTRICULAR TACHYCARDIA (SVT)
The supraventricular tachycardia is a type of arrhythmia characterized by rapid, sustained palpitations that start and stop abruptly.

BUNDLE BRANCH BLOCK
Defects of electrical conduction by the two specialized branches of the ventricles can occur. One calls these conditions bundle branch blocks - right if it affects the right branch and left if it affects the left branch.
ATRIAL FIBRILLATION (AF)
AF is an arrhythmia characterized by chaotic cardiac beats which are irregularly irregular.
Atrial flutter is an arrhythmia characterized by a very fast, but regular heartbeat. It can climb beyond 150 beats per minute.
