What is heart arrhythmia?

Reports have stated that Aguero is suffering a heart arrhythmia, which means an irregular heartbeat is either too quickly (tachycardia) or maybe too slow (bradycardia). It can be too or beating with an irregular rhythm. However, it's normal for a person to have a fast or slow heart rate. 

Some studies based on the same have shed light upon heart rhythm problems, stating that the issues occur when the electrical signals that coordinate the heart's beats don't work properly. Heart arrhythmias may feel like a fluttering or racing heart and may be harmless, however, in cases, the condition can cause problems, sometimes even life-threatening.
