Facts About Irregular Heartbeat
The electrical system present in the heart controls the pace and rhythm of our heartbeat. In normal circumstances, the rate of our heartbeat remains between 50 to 100 beats per minute. Irregular heartbeat or arrhythmia is the irregular rhythm of the heartbeat.
Arrhythmia can occur when the heart is beating too fast, the condition known as tachyarrhythmia, when the heartbeat rate is above 100 beats per minute. Irregular heartbeat can occur with bradyarrhythmia, when heartbeat rate is less than 60 beats per minute. Irregular heartbeats can also occur with normal heartbeat rate.
Irregular heartbeats are often harmless. But sometimes they may become fatal. In certain instances, the causes of irregular heartbeats are not quite clear. However, heart ailments, changes in the heart muscles, heart attack, electrolyte imbalance, stress, smoking, and drug and alcohol abuse are responsible for irregular heartbeat. Risk of arrhythmia is highest among people suffering from heart ailments, hypertension and sleep apnea. Sometimes arrhythmia is present in individuals since birth.
