Which electrolyte helps regulate cardiac impulse transmission and muscle contraction?

∙ 14y ago
Potassium has the main direct effect on cardiac impulse transmission and muscle contraction. However, potassium (K+) and sodium (Na) have an inverse relationship; when one is increased the olther is decreased. In cardiac health, both must be balanced to effect homeostasis. This is why repeat electrolyte lab values and cardiac enzymes are so important in unstable cardiac patients.

Which electrolyte has a major role in muscle contraction and high or low levels of it can leacd to cardiac arrest?
potassium
What ion is necessary for cardiac contraction to occur?
calcium is te most important ion in cardiac contraction , whereas the contraction starts by the Na .
Does cardiac electrical activity immediately precede the contraction of the cardiac muscle?
Yes
Term for the blood pumped in a single contraction?
Cardiac volume is the blood pumped in a single contraction
Each heart contraction begins in a small group of cardiac muscle cells called?
The sinoatrial node is the small group of cardiac muscles that initiates each heart contraction.
The R wave of the ECG is most closely associated with which phase of the cardiac contraction cycle?
Ventricular contraction.
What is automaticity of the heart?
The property that allows any cell in the cardiac muscle to begin an action potential, or a cardiac conduction, leading to cardiac contraction.
What muscles are straited?
smooth skeletal cardiac and contraction mbroro
What type of muscle show rythemic contraction?
Cardiac muscles.
Basic unit of contraction in skeletal and cardiac muscle?
The Sarcomere
The portion of the nervous system that most closely associated with the contraction of cardiac muscle is The?
The portion of the nervous system that is most closely associated with the contraction of the cardiac muscle is the autonomic nervous system.
What is the alternating relaxation and contraction of the heart called?
Diastole is the relaxation phase. Systole is the contraction phase. If you put these phases together you have the Cardiac Cycle...
