My opinion
My theory is that the conduit that carries the electric current through the heart is damaged. I do not know what the conduit is made of or what causes the damage in each specific person. But I theorize that the conduit that carries the charge is the key factor for a cure.
New to this forum . the Poll interesting , thanks..took me back to a time spent figuring out how the electrical part works.. believed the brain sent currant to ignited the heart...boy was I wrong ..now ten years later trying to investgate why my 25 year old son has muscle Harding around his heart..at fifteen he was experiencing at rest sinus Rythm.frequent premature ventricular contractions .early repolarization his Eco ultrasound and stress test normal rhythm,I was told they were normal ,he is a professional athlete had a fall went to emergency room found issues with heart rhythm. sournding muscle is harding ..he is in hospital ,
The conduit that I am theorizing about does not have any electrical properties. It's only function is to protect the cells that are part of the electric circuit.
This is the second time for writing this response...hit the wrong key and lost data %#@#
But a short answer to your question correcting the pathway is not cure to some heart conditions that are electrically and rhythm based. It can remedy some rhythm problems that are the fault of more than one pathway or blocked pathway.
The subject of your question is complicated and involves chemistry, nervous system, specialized heart cells:
Sympathetic nervous system accelerates the heart and two chemicals are influenced by the sympathetic system – epinephrine & norepinephrine these chemicals increase heart rate, contractibility, automaticity, and AV conduction (ability to pass electrical impulses).
Parasympathetic nervous system slows the heart. The vagus nerve is one of this systems nerves, when stimulated slows heart rate and AV conduction.
Cardiac cells – two types, electrical and myocardial (``working"):
Electrical cells make up the conduction system of the heart and are distributed in an orderly fashion (pathways) through the heart. They are specific cells to automatically generate and discharge an electrical impulse. Conductivity – the ability to transmit an electrical impulse from one cell to the next the ability of the cell to respond to an electrical impulse.
Myocardial cells respond to an electrical impulse and make up the muscular walls of the atrium (upper chambers) and ventricles (lower chambers) of the heart. They possess specific properties contractility – the ability of the cell to shorten and lengthen its fibers, and extensibility – the ability of the cell to stretch. And this is accomplished by polarizing and repolarizing (charging and discharging) 4. Once an electrical cell generates an electrical impulse, this electrical impulse causes the ions to cross the cell membrane and causes the action potential, also called depolarization and it is the movement of ions across the cell membrane through sodium, potassium and calcium channels, is the drive that causes contraction of the cardiac cells/muscle. Then there is a relaxation pahase.
Electrical charge measured in microvolts would vary as shown on an EKG. An electrical impulse pathway would be a conduit although I haven't heard the word used for a pathway.
