Dr. Preetam Krishnamurthy, M.D. (Med - PGI, Chd), D.M (Cardiology - AIIMS, New Delhi), P.D.F (Electrophysiology) says, “The normal heart rate for an adult ranges from 60 to 100 beats per minute. Arrhythmia can lead to feeling of dizziness, shortness of breath and excessive sweating. Arrhythmia is caused by congenital diseases, smoking, and alcohol consumption.”
“However, not all irregular heartbeats mean there is a problem in the heart. During physical activities, it is normal for heartbeats to speed up. Similarly, when a person is resting or sleeping, it is normal to have slow heartbeats. But a frequent irregular rhythm may mean that the heart is not pumping enough blood for the body,” he adds.
