I believe the heart is a different kind of muscle tissue than the skeletal muscles. It is contiuously working to pump blood, whereas other muscles need to rest. It wouldn't do to well to have a heart muscle that periodically stopped or failed - as in the case of a heart attack.fluidistic said:Is it possible to have a cramp in the heart? It would differ from heart attacks I think, but would also being able to kill. So a simply low level of sodium/potassium/calcium in blood could cause us a cramp in the heart and maybe kill us. I just wonder if it's possible. If not, why?
Ref: http://www.medicinenet.com/muscle_cramps/article.htmAnyone who has experienced a muscle cramp (charley horse) can attest to the fact that it can be quite painful. Muscle cramps occur when muscles involuntarily contract and cannot relax.
The skeletal muscles (those over which we have voluntary control) are most prone to cramping. The skeletal muscles in the calf, thigh, and arch of the foot are most notorious sites of cramps.
Cramps can be perceived as mild twitches or may be excruciatingly painful. Typically, cramps cause an abrupt, intense pain in the involved muscle.
Often a muscle that is cramping feels harder than normal to the touch or may even show visible signs of twitching. Most cramps resolve spontaneously within a few seconds to minutes.
It is not known exactly why muscle cramps develop. Insufficient stretching before exercise, exercising in the heat, and muscle fatigue may all play a role in their causation. Imbalances in the levels of electrolytes (sodium, potassium, chloride, calcium and phosphate) in the blood can also lead to muscle cramps.
Leg pain can be due to a muscle cramp (also called a charley horse). Common causes of cramps include:
Dehydration or low amounts of potassium, sodium, calcium, or magnesium in the blood
Medications such as:
Diuretics, which can cause you to lose too much fluid or minerals
Statins, which lower cholesterol and can cause muscle injury
Muscle fatigue or strain from overuse, too much exercise, or holding a muscle in the same position for a long time
, it does not explain why muscles on which we have a voluntary control are more prone to cramps than the others muscles. And this "more prone to cramp" doesn't seem to exclude totally cramps on the other muscles such as the heart.The skeletal muscles (those over which we have voluntary control) are most prone to cramping. The skeletal muscles in the calf, thigh, and arch of the foot are most notorious sites of cramps.
Muscle cramps can be caused by a variety of factors, including dehydration, electrolyte imbalances, overuse or strain of muscles, and certain medical conditions. They can also be a side effect of certain medications or a result of poor circulation.
To prevent muscle cramps, it's important to stay hydrated and maintain a balanced diet with adequate amounts of electrolytes such as potassium, magnesium, and calcium. Stretching and warming up before physical activity can also help prevent cramps.
In most cases, muscle cramps are not dangerous and will resolve on their own. However, if you experience cramps frequently or they are accompanied by severe pain or other symptoms, it's important to consult a doctor to rule out any underlying medical conditions.
While heart problems can sometimes cause muscle cramps, it is not a common symptom. Muscle cramps are more often caused by factors such as dehydration, overuse, or electrolyte imbalances.
If you experience a cramp during exercise, stop the activity and gently stretch and massage the affected muscle. Drink plenty of water and wait for the cramp to pass before resuming physical activity. If the cramp persists or is accompanied by severe pain, seek medical attention.
