Hiatus Hernia and Palpitations

Took the title out of a forum. But i knew it for a long time. There is a link between the two and i'm going to try to explain it. Doctors don't know because they don't look at this from the mechanical point of view. Here is a video called just like that. The mechanics of breathing.
You don't have to look more than a few seconds at this video to realize diaphragm plays most important role in breathing. But you don't have to look more than a few seconds and the second video to realize what i'm trying to say. They don't regard it as a whole. Can't and wouldn't find an animation that would actually show both motions in the same time. Cause they didn't though of it.

Figure anything already?

What is hiatus hernia? Diaphragm is a large dome shaped muscle that separates the abdominal and thoracic cavities and also plays an important role in breathing.

Hiatus hernia is when you stomach pushes through you diaphragm and actually the tip of the stomach starts to actually pass through the hole in the diaphragm. It also happens of mechanical causes. Two of them actually. One is gas in the abdominal cavity due to gas retention. Second is nasal congestion. Nasal congestions make breathing more difficult and when the thorax expends not enough air gets in the lung creating a partial vacuum that also "sucks" the stomach through the diaphragm. Heart does not sit there loose on the diaphragm If it was like that it would move all the time and press against the sponge like, soft lungs. It is anchored both on diaphragm and thoracic wall with what they call connective tissue. Also on top of it is the aortic arch, vena cava that won't allow the heart to raise too much during breathing. As a result, if diaphragm raises too much because of gas and congested breathing it will simply start squeezing the heart. Also the tip of the stomach raisng through the diaphragm will start touching the heart interfering with expanding.

Heart like any muscle can only contract. For the left atrium to get filled with blood heart relies only on venous pressure which is low close to nothing cause blood returning from tissues doesn't have much pressure. If heat gets raised too much by the rising diaphragm it will simply would not have enough room for the left atrium to expand under the pressure of venous blood. It will also twist the heart because it is also anchored on the thoracic wall interfering with the heart's pacemaker. In other words the whole mechanics of the beating of the heart are affected by the combination of nose congestion and abdominal gas retention. Usually this happens a lot to sedentary people who sit all they at a computer desk. As soon as you start to move gas will eliminate from you abdominal cavity making more room to heart to beat. Also sober people realize when they have a severe nose congestion and start open the mouth to breath. Trouble begins when under influence of substances like alcohol or drugs. I will not enter now in the details but basically you don't realize you are having difficulties breathing through the nose or you are full of intestinal gas. If that situation gets prolonged in time it may actually lead to heart failure or even death because heart not be able to fill enough with venous blood due to lack of room to expand.

I personally when i have palpitation i simply try and start breathing on my mouth and they go away eventually. My nose congestion also occurs because of vapors of hydrochloric acid coming from stomach again due to hiatal hernia. As soon as i go for a walk and breath on my mouth for a few minutes the stomach gets back into the abdominal cavity and everything gets back to a more normal physiology.
