What are the signs of arrhythmia?

Dr. Vivek Y. Reddy, MD
Cardiac Electrophysiologist

Occasionally people experience palpitations, or heightened awareness of their heartbeat. It is common for the heart to race during exertion or emotional stress.

When the rhythm disturbances are prolonged or linger, they may be clues to an underlying heart condition. Certain abnormal heartbeats can be life threatening, even in the absence of overt heart disease symptoms. Watch for the following signs associated with palpitations and see a doctor if they persist:

  • Fatigue
  • Long pauses between heartbeats
  • Unusual sweating
  • Shortness of breath
  • Chest pain
  • Light-headedness and dizziness
  • Fainting
