What will happen if cardiac muscle rest for a while

  • Cardiac muscles work continuously without stopping.
  • When the heart beats, it pumps blood to your lungs and the rest of your body.
  • But in between beats, the heart muscle relaxes as it fills with blood. It relaxes only for a moment after each contraction, but that still counts as resting.
  • However, the cardiac or heart muscles never stop working. In case they stop working, there will be no blood flow to the body organs and there are chances of multiple organ failure and eventually death.
