Heart Alterations

11/02/2024
Next up is the shape of the heart and the rhythm that changes the strength of contractions. Below, is an example of the heart in what’s known as normal sinus rhythm. It’s so called that way because that’s what it looks like most of the time when everything’s working fine. The Bundle of His gets the electrical message from the brain coming in through the nerves. Then, the heart will get the message to beat as the message passes as electrical impulses through the Purkinje Fibers. Any issues found in the heart, will be seen on this rhythm strip here. Before we address what could possibly go wrong, let’s first figure out a normal response. The large upside down V waves along with the two little v’s one before and after signal a normal beat of the heart.

Basically, that’s how long it takes the blood to make a complete cycle around through the heart, into the lungs, and from there into the body it flows. The little v out in front, means the blood has just filled the little chamber up at the top. From there, you see a heart squeeze as it goes into the ventricles and out through the lungs. From there, the blood rushes back into the left side of the heart where it gathers for it’s one last long push out to the fingers and toes. This path creates the dramatic upside-down V that you see. In this part, the blood will have gone from the heart as into the body it flows. From there, the heart will rest just prior to it’s next regular contraction. This rest is shown as the relaxing of the next largest V. It’s important for the heart to have it’s rest, otherwise the heart could grow erratic, stressed out of control. It’s sort of like you when you suddenly find too much to do. Sure, you can keep up for a while, but after some time it gets too hard to keep up. The heart behaves much the same way. 


 On average, it takes about 60 to 100 beats per minute to keep up with the normal demands of the heart. For infants and children, it will be some higher as the rate changes based upon age. Heart rates too fast or too slow are known as tachycardia and bradycardia, relatively speaking. If the heart is too fast, it’ll be tachycardic as previously said. The heart rhythm will grow faster and a lot closer together. Bradycardia results from the heart beating too slow, where the heart waves get slower and a lot further apart. Either one of these is dangerous because of the risk that the heart will eventually stop. Physical attraction, rejection, circumstances, stress, or the state of the mind will also mimic some of these previous forms. The reasons for that are quite simple. Since the brain controls the heart deep at it’s base, any sudden stress or a shock can result in a sudden change in the heart. That’s why you’ll hear of people fainting after the reception of horrible news. Sudden events, accidents, or injury to the back of the brain can also affect the shape of the heart. That’s why it’s best to send these people straight to the hospital for some additional tests. Then again, sometimes you’ll notice your heart racing suddenly at the sight of someone you love. That’s because it’s not kidding, your brain really loves them a lot. Your heart does too, but of course. 


From there, we’ll look at the next waves of the heart. This is what happens as the heart is damaged or stressed resulting in the rhythm’s loss of control. Here’s what happens when there’s something blocking the signals from reaching certain parts of the heart. This is usually a nerve-muscle connection issue. The image below shows what happens at first, as the heart strengthens it’s beats in an effort to keep up with the demands made on it. It can’t quite though and the heart block persists. That’s when the heart transitions from phase one to phase two. The heart beats are coming some fast and some slow. That’s what you’d call an irregular rhythm. After a while, the fast heart beats will stop and all will be slow. That’s because the heart muscle is finally growing fatigued. Then in the third degree, you’ll find the heart has ceased to create it’s usual escape. 


The blood’s coming into top of the heart and the period of rest just after have all been messed up. If this continues unchecked, death will result. Sure, you might be able to administer shock to restore the heart to it’s regular rhythm, but this is usually done in one last frantic effort to save a life. Sometimes, little electrical devices known as pacemakers are installed at this point to clear the faulty electrical system. These sit there safe from their place on top of the chest, until a bad heart rhythm is detected deep down inside. The pacemaker is trained to recognize these automatically and then deliver a shock clearing the rhythm. If you have someone who’s hearing the end of life and has one of these, this device will have to be finally turned off. Doing so prevents the occurrence of unnecessary and sometimes traumatic situations. I mean, just imagine the image that poor person’s family would have to endure. It’s better to just explain the situation, I think.
