Muscle damage following a heart attack may disrupt
normal heart conduction, resulting in a condition known as cardiac dyssynchrony.
Not exact matches
When the
heart repolarizes, the
normal electrical
conduction may assert itself, in which case the ventricular arrhythmia is terminated.
«These electrolytes in turn support nerve
conduction, muscle contraction, and maintain
normal heart rhythm.»
Magnesium also plays a role in the active transport of calcium and potassium ions across cell membranes, a process that is important to nerve impulse
conduction, muscle contraction, and
normal heart rhythm [3].
Only a fraction of the electrical impulses are able to travel across the AV node and down through the
heart's
normal conduction system (the «wiring») to make the ventricles contract.
The specific arrhythmia with this disease is called ventricular premature complexes (VPC), these are early abnormal
heart beats originating from the
heart muscle instead of the specialized
conduction tissue in the
heart where
normal heart beats originate.
«The reason for his fast
heart rate was due to a congenital problem called an accessory pathway, where the electrical
conduction in his
heart has the
normal pathway plus an extra pathway.
