Human heartbeats around 60 to 80 beats per minute. This beating, also called contraction and relaxation of heart muscles occurs due to an electric impulse that passes through heart muscles.
When this electric impulse gets delayed or stops completely, it prevents the heart from beating regularly. This condition is called Heart Block.
Heart block can be classified into the following types on the basis of electric impulse
Partial Heart Block
In this condition, the electric impulse gets delayed or stopped for a period of time.
Complete Heart Block
In this condition, the electric impulse stops completely causing the heart to stop beating.
First Degree Heart Block
In this condition, the heart receives delayed electric impulses. This condition is many a time self-limiting and is the least dangerous.
Second Degree Heart Block
In this case, the heart may not receive the electric impulse at the correct place causing skipped heartbeats.
Third Degree Heart Block
In this condition, the heart does not receive electrical impulses at all. This condition can prove fatal.
