What Does An Icd Shock Feel Like?

You may feel a flutter, palpitations (like your heart is skipping a beat), or nothing at all.

Fibrillation may require that you receive a “shock.” Most patients say that the shock feels like a sudden jolt or thump to the chest.

Do ICD shocks hurt?

Do shocks from an ICD hurt? Most patients who have received shocks from their ICDs describe them as startling, jolting and unsettling, but not painful. It’s easy to understand why. The ICD delivers a shock to prevent a dangerously fast heart rhythm.

What should I do if my ICD shocks me?

Here is an example:

  • After one shock: Call 911 or other emergency services right away if you feel bad or have symptoms like chest pain. Call your doctor soon if you feel fine right away after the shock.
  • If you get a second shock in a 24-hour period, call your doctor right away. Call even if you feel fine right away.

What are the side effects of a defibrillator?

  5. Bleeding around your heart, which can be life-threatening.

Can you get a shock from a defibrillator?
