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

之前使用脏肌肉能量运行起搏器的尝赖于压电材料。

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

另一方面，你的肌组织不由自主地工作的。

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

破伤风仅影响骨骼肌，因此，平滑肌和肌仍能继续工作。

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

他们构成了大部分脏组织，这因为肌细胞能收缩，从而实现泵血。

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

高钾血症，也可以影响肌细胞收缩，进而导致律失常和脏停搏。

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

最后，低钾血症会影响肌收缩，导致律失常和搏骤停。

Blood flow is cut off to the cardiac muscle and the oxygen-starved cells start to die within several minutes.

通往肌的血流被阻断在几分钟内缺氧的细胞开始死亡。

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

具有这蠕动功能的肌肉平滑肌，骨骼肌或肌则没有该功能。

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

径的低钾水平都会导致肌肉收缩的问题，可累及平滑肌、骨骼肌或肌。

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

与骨骼肌不同，身体的肌和平滑肌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，或只一个肌细胞。

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

你的肌也条纹状的，通过滑动的细丝来收缩，但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，骨骼和肌组织之间的差异理解它们功能的关键。

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房的肌细胞。

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

无论哪方式，高钾血症可以导致肌肉收缩问题，可能平滑肌细胞、骨骼肌细胞或肌细胞。

Normally, all my sites are depolarized at this time, and there is no electrical flow in the cardiac muscle.

正常情况下，所有区域同时去极化，肌没有电流。

The current stops the irregular contractions of the cardiac muscle, and gives the heart a chance to start beating normally.

电流停止了肌肉的剧烈收缩 脏，并让脏有机会正常跳动。

Cardiac muscle tissue is also striped, or striated, but unlike skeletal muscle tissue, their cells are generally uninucleate, meaning that they have just one nucleus.

脏肌肉组织也有条纹，但与骨骼肌组织不同，它们的细胞通常无核的，这意味着它们只有一个细胞核。

Hypertrophy refers to an abnormal increase in the size of each cell, for example, the increase in cell size of cardiac muscle.

肥大指每个细胞大小的异常增加，例如，肌细胞大小的增加。

You also learned how your skeletal, smooth, and cardiac muscle tissue facilitates all your movements, both voluntary and involuntary, and how to identify each in a sample.

你们还了解了你的骨骼、平滑和肌组织如何促进你所有的运动的，无论自愿的还非自愿的，以及如何在样本中识别每一个。
