Cardiac arrhythmias is a group of cardiac condition marked by irregular and nonuniform patterns of heartbeat, both fast and slow. It is caused due to dysfunctioning of the electrical impulses which coordinate a person's heartbeat. Shortage of breath, stiffness of the chest, dizziness and increased or decreased heart rate are some of the noticeable symptom. Stress, diabetes, genetics, alcohol and drug abuse are just some of the causes. Arrhythmias are divided into two categories in accordance to the rate of heartbeat either fast or slow. A rate of over 100 beats per minute would characterize a fast heart rate while a rate of 60 beats per minute would fall under the category of slow heart rate.
