● Causes of heart palpitations The most common causes of abnormal heart rhythms or murmurs are the following:
1- Tachycardia, Tachycardia means that your heart is beating too fast, as the normal heart beats 60-100 times per minute in adults.
If you have this disorder, your heart rate increases more than 100 beats per minute. There are three subtypes of tachycardia:
Supraventricular tachycardia in the upper part
of the heart known as the atrium.
Ventricular tachycardia in the lower part of the heart known as the ventricles.
Sinus tachycardia, where you have a normal increase in your heart rate during illness for example when you are sick, but your heartbeat returns to normal once you get better.
2- Atrial fibrillation, this irregular heart rhythm occurs in the upper parts of the heart, and is one of the most common arrhythmias.
Atrial fibrillation occurs when many unstable electrical impulses malfunction, leading to atrial fibrillation and loss of control.
It can raise the heart rate to 100-200 bpm, which is much faster than normal.
3- Bradycardia, if you suffer from bradycardia, this means that the heart rate is less than 60 beats per minute, as bradycardia generally occurs when the electrical signals transmitted from the atria to the ventricles are disrupted.
Some athletes may experience a slow heart rate because they are in excellent physical condition, and this is not usually caused by exercise

4- Ventricular fibrillation. This type of abnormal rhythm can stop the heart from beating and cause cardiac arrest. It occurs in the ventricles, where the blood becomes unable to pump blood from your heart to the body and brain, causing a heart murmur.
Ventricular fibrillation is a serious condition that can lead to death if not treated immediately.
5- Coronary heart disease. This serious heart problem occurs when cholesterol and other deposits block the coronary arteries.
● Prevention and treatment of heart attacks, thoughFeeling heart palpitations can't be too dangerous. Many cases of arrhythmias can be controlled with treatment, and it's best if your doctor monitors your condition with regular check-ups.
In general, healthy lifestyle choices can play an important role in helping you control your condition, and your doctor will likely recommend improving your diet, exercising more, and trying to end other risky behaviors such as; smoking
