Previous attempts to use cardiac muscle power to run pacemakers relied on piezoelectric materials.

之前使用心脏肉能量运行起搏器的尝试是依赖于压电材料。

And titin is one of three key proteins in our cardiac and skeletal muscle.

联蛋白是我们心脏和肉中的三大关键蛋白质之一。

Tetanus only affects skeletal muscle, so smooth muscle and cardiac muscle continue to function normally.

破伤风仅影响，因此，平滑和心仍能继续工作。

This forms the bulk of the heart tissue, because those cardiac muscle cells contract and pump blood.

他们构成了大部分心脏组织，这是因为心细胞能收缩，从而现泵血。

Finally, hypokalemia can affect cardiac muscle contractions, which can lead to cardiac arrhythmias and cardiac arrest.

最后，低钾血症会影响心收缩，导致心律失常和心搏骤停。

Hyperkalemia, though, also affects cardiac muscle contractions, which can lead to cardiac arrhythmias and cardiac arrest.

高钾血症，也可以影响心细胞收缩，进而导致心律失常和心脏停搏。

The type of muscle that causes these contractions is smooth muscle, as opposed to skeletal muscle or cardiac muscle.

具有这种蠕动功能的肉是平滑，或心则没有该功能。

Low potassium levels leads to issues with muscle contractions, which could be smooth, skeletal, or cardiac muscles.

两种途径的低钾水平都会导致肉收缩的问题，可累及平滑、或心。

Your cardiac muscle is also striated, and uses sliding filaments to contract, but the similarities end there.

你的心也是条纹状的，通过滑动的细丝来收缩，但是相似之处就到此为止了。

Not surprisingly, the differences between skeletal and cardiac muscle tissues are key to understanding their functions.

毫不奇怪，和心组织之间的差异是理解它们功能的关键。

Unlike the skeletal muscles, the body's cardiac and smooth muscles are managed by the autonomic nervous system beyond our direct control.

与不同，身体的心和平滑是由自动神经系统控制，而非听从我们的直接控制。

Now this can be a cell that's part of the conduction system or it can just be another cardiac muscle cell.

这个细胞可能属于传导系统的一部分，或只是一个心细胞。

Your cardiac muscle tissue, on the other hand, works involuntarily.

另一方面，你的心组织是不由自主地工作的。

After those pacemaker cells make themselves fire, they spread their electrical impulses to cardiac muscle cells throughout the atria.

这些起搏细胞自我激活后，它们将电脉冲传播到整个心房的心细胞。

These procedures reestablish circulation to the cardiac muscle, restoring heart function.

这些手术重新建立心脏肉的血液循环，恢复心脏功能。

So your heart is muscle, it's cardiac muscle.

所以你的心脏是肉，它是心。

There's smooth muscle, a muscle within the arteries, the uterus and cardiac muscle.

存在于动脉、子宫内， 还有心。

That's the electrode structure that directly interfaces to the cardiac muscle to deliver that electrical stimulation.

那就是直接与心接触以传递电刺激的电极结构。

Either way, the high potassium levels leads to issues with muscle contractions, which could be issues with the smooth, skeletal, or cardiac muscles.

无论哪种方式，高钾血症可以导致肉收缩问题，可能是平滑细胞、细胞或心细胞。

We have skeletal muscle attached to our bones and we have cardiac muscle, which is our heart.

我们身体有附着在上的，还有心脏所特有的心。
