Bradycardia
Bradycardia is a condition in which individual heart rate is very slow. It can be defined typically as a resting heart rate of below or under 60 beats per minute in adults. It does not show any symptoms until the rate drops below 50 beats per minute (BPM).
Whenever it show symptoms it shows symptoms like fatigue, weakness, dizziness, sweating, and at very low rates, fainting. During sleep, a slow heartbeat with rates around 40–50 BPM is common, and is considered normal. Highly trained athletes may also have athletic heart syndrome, a very slow resting heart rate that occurs as a sport adaptation and helps prevent tachycardia during training.
The term relative bradycardia is used in explaining a heart rate that, although not actually below 60 BPM, is still considered too slow for the individuals current medical condition.
Classification:
· Sinus
· Antrioventricular node
· Ventricular
· Infantile
Cardiology research Journals like Clinical Cardiology and Cardiovascular Medicine (CCCM) provides a global open access platform to put forth the ongoing research, reviews articles of bradycardia.
