WHAT IS IT?
There is talk of heart failure when heart function is impaired or not pump enough blood supply to the organs, muscles and tissues. When the heart begins to fail, the body immediately detects it and triggers compensatory mechanisms, so that many patients fail to perceive symptoms manifest abnormal heart. These mechanisms are only effective for a while, so there comes a time when the body is unable to remedy the defect in the heart’s pumping. Read the rest of this entry »
Studies in consultations of various cardiologists, investigating the causes behind the first visits of patients, showed that 56 out of 100 come to present some kind of pain in the anterior chest, neck or left arm. Of these, only 15 actually suffer from heart problems.
In view of these results shows the sensitivity of the population to any pain like this. But it also reveals the existence of a large number of diseases that can cause this kind of pain when the heart is directly responsible. In many cases, despite making extensive medical study, you get to discover the cause that produces the pain, qualifying for nerve pain, reflex or the dreaded neurasthenia.
The somatic pain , which occurs in our own structures, have origins very different . Occurring in most of the viscera, in almost all tissues, specific receptors for pain (structures nerve cell terminals that transmit pain and captan). Read the rest of this entry »
Everyone knows too much cholesterol in the blood increases the risk of developing heart disease. But did you know that nearly 80% of the cholesterol in the blood is produced by your liver? Extenso reveals all about the effects of cholesterol on the heart …
When arteries are blocked …
Blood cholesterol is a fat carried in the blood. This is a base material of body cells and is necessary for the production of steroid hormones. However, when cholesterol is too much blood, it builds up in the arteries. These ducts are blocked then gradually to prevent the circulation of blood through the body. Blood carries oxygen and nutrients to body cells. Unable to move properly, the heart works harder and fatigue. Undernourished cells deprived of oxygen and die. It is at this point that the heart failure, stroke or myocardial infarction.
In Canada, 80% of heart disease could be prevented through a healthy diet and an active lifestyle and smokeless. And among the risk factors for cardiovascular disease, at least three can be connected to the power supply:
1. high levels of blood fats (hyperlipidemia)
2. fat accumulation in the abdomen (abdominal obesity)
3. and low consumption of vegetables and fruits. Read the rest of this entry »
[Heart block]. Slowing or stopping transmission of the electrical signal, or conduction, intracardiac generated by the sinus node and responsible for the contraction of the heart. Blocks cause heart rhythm disturbances, or arrhythmias. -> Arrhythmia, sinus node. Atrioventricular block, or atrioventricular syn. : AV block, syncope Stokes-Adams [atrioventricular heart block], is located between the atria and the ventricles. In the first degree block, incomplete or partial, all pulses reach the ventricles but slowed conduction (prolongation of the PR interval on the electrocardiogram). Read the rest of this entry »
The heart is responsible for carrying oxygen to the body by the bloodstream. When the heart beats too slow, can not perform this function as efficiently. This causes symptoms such as lightheadedness and fainting.
What is heart block?
The beats are controlled by electrical signals (impulses), which begin in one part of the wall of the heart called the sinus node and traveling through the heart causing it to contract. Signals travel from the atria (upper heart chambers) to the ventricles (lower chambers) through an area called the atrioventricular (AV). The AV node helps to synchronize the pumping action of the atria and ventricles.
If you have heart block, this means there is a problem that affects the transmission of electrical impulses through your heart. When the problem occurs in the atrioventricular node, prevents signals from passing through the atria into the ventricles. This is called atrioventricular block. There are three different degrees of atrioventricular block. Read the rest of this entry »
