What Is The Relationship Between Cardiac Ischemia And Shortness Of Breath
Mathematical: The relationship can be expressed as a variant of darcy' law; flow (q) = pressure/resistance. In the human circulatory system: q = (map – rap)/tpr (map = mean aortic (or arterial) blood pressure in mmhg, RAP = mean right atrial pressure in mmhg and tpr = total peripheral resistance in dynes-sec-cm-5.) however, as map>>rap, , this can be simplified to: q~map/tpr. Map is obviously affected by htn. ...Read moreSee 1 more doctor answer

Category...: Cardiac arrest means that the heart is no longer beating and this can be due to different rhythm disturbances. One of the rhythm disturbances that can lead to the heart stopping is asystole, when there is no electrical activity present (ie "flat line" on the heart monitor!). ...Read moreSee 1 more doctor answer
Complicated.: It is an indirect relationship. Hypertension over time can lead to changes in the heart muscle and heart function. It may eventually lead to heart failure. When this ensues the output of the heart can eventually decline and cause serious symptoms. In the earlier stages if hypertension cardiac output actually goes up. ...Read moreSee 1 more doctor answer
Longer pain..: Insufficient blood flow to the heart usually during exertion or other forms of stress due to a partial blockage causes chest pain lasting 5 to 10 minutes and is referred to as angina. Persistent complete or near complete interruption of blood flow to the heart muscle results in permanent damage and is referred to as a heart attack. The pain usually lasts much longer than 5 to 10 minutes. ...Read moreSee 1 more doctor answer
Continuum: Angina can be quite severe and respond to rest, oxygen, nitroglycerin. And fully recover with no muscle death. The pain fibers are the same source. Some myocardial infarction can be asymptomatic all the way to the worst, ominous, pain ever! there is heart muscle death as the defining entity may need surgery or intervention. ...Read moreSee 1 more doctor answer
Blocked artery: Heart attacks are almost always caused by a blockage in one of the arteries that supplies the heart. This stops the flow of blood (and oxygen) to that area of the heart and eventually the involved area of muscle dies. Heart failure is most often the result of several small or one large heart attack that affects enough muscle to keep the heart from being able to pump blood effectively. ...Read moreSee 1 more doctor answer
Asystole is the end: Asystole, or a heart with no electrical activity, is how we all end up at death. A cardiac arrest can start there, but usually starts with a rapid rhythm that has low or no output or a noncontractile rhythm (ventricular fibrillation). These rhythms are often reversible, asystole is usually simply death. ...Read moreSee 1 more doctor answer
Sensation vs. Rhythm: Palpitations are the sensation of skipping or abnormal heart beats. These might be from abnormal beats, or just the normal rhythm beating fast or stronger than normal. Heart arrythmias are actual, documented (by ekg, holter, event monitor) abnormal heart contractions. ...Read more
