Both types of arrhythmias, such as bradycardia and tachycardia, are often caused by overstimulation of the vagal or sympathetic division of the nervous system. For example, excessive adrenaline may result in tachycardia.
A way to get rid of this specific cause of heart arrhythmia would be to reduce the excess vagal or sympathetic tone.
Once this has been achieved, balance will return.
One of the causes and risk factors of heart arrhythmias involve medical conditions related to the heart, as they can affect the organ’s function. Eventually, these conditions may cause heart arrhythmias. To name a few, severe heart conditions such as coronary artery disease, cardiomyopathy, and heart valve disease can result in life-threatening arrhythmias.
So if you are someone who has had a heart attack or heart failure, there is a need for you to take necessary steps to reduce the risks of having bouts of arrhythmias.
