Normal Heart Sounds With the aid of a stethoscope you can hear the characteristic sounds of the normal heartbeat, typically described as a "lub-dub." These sounds are produced by the closure of the heart valves. The first heart sound or "lub" results from closure of the tricuspid and mitral valves. It is a rather low-pitched and a relatively long sound which, as indicated in, represents the beginning of ventricular systole. The second heart sound, or "dub," marks the beginning of ventricular diastole. It is produced by closure of the aortic and pulmonary (pulmonic) semilunar vanes when the intraventricular pressure begins to fall. This "dub" sound is typically heard as a sharp snap because the semilunar valves tend to close much more rapidly than the AV valves. Because diastole occupies more time than systole, a brief pause occurs after the second heart sound when the heart is beating at a normal rate. Therefore, the pattern that one hears is one of: "lub-dub" pause, "lub-dub" pause, and so on. Sometimes, especially in young normal individuals, a third heart sound can be heard. This sound is produced by the very rapid influx of blood into the partially filled ventricle. It is typically very faint and as such difficult to hear.

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

Recent studies show that administration of PEA in glaucoma patients has a double effect, decrease the IOP and neuroprotection. The IOP is the major risk factor in glaucoma, constricts blood vessels and reduces the delivery of oxygen and nutrients to the retina and optic nerve (ON), causing a process of ischemia and cell death (apoptosis).
New research points out palmitoylethanolamide has a dual action in glaucoma:

1. It reduces high eye pressure by promoting fluid flow out of the eye, and

2. PEA protects nerve cells and retina cells via its neuroprotective and reparative properties.

In the Youtube the essence of the natural treatment of glaucoma with palmitoylethanolamide has been summarized. Daily dose: 2-3 times 400 mg palmitoylethanolamide.

Pulmonary fibrosis is a condition in which the tissue deep in your lungs becomes scarred over time. This tissue gets thick and stiff. That makes it hard for you to catch your breath, and your blood may not get enough oxygen. Causes of pulmonary fibrosis include environmental pollutants, some medicines, some connective tissue diseases, and interstitial lung disease. Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. In most cases, the cause cannot be found. This is called idiopathic pulmonary fibrosis

The majority of all headaches are tension related headaches. The blockage of blood circulation along with contraction/shortening of muscles is what causes this condition. This simple technique can take away most tension related headaches in seconds.

The heart, blood vessels, and blood are the parts that make up the circulatory system, which is defined as a closed system of blood vessels for the transport of gasses and nutrients. The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body.

The 12-lead ECG is a vital tool for EMT’s and paramedics in both the prehospital and hospital setting. It is extremely important to know the exact placement of each electrode on the patient. Incorrect placement can lead to a false diagnosis of infarction or negative changes on the ECG.

Basic ECG Interpretation Our ECG Interpretation Training and Reference Guides provide basic lessons for ECG analysis as well as a quick reference guide for over 40 types of ECG tracings. The arrhythmia drills and quizzes allow you to practice ECG interpretation. What is ECG Interpretation? An electrocardiogram or ECG, records electrical activity in the heart. An ECG machine records these electrical signals across multiple heart beats and produces an ECG strip that is interpreted by a healthcare professional. How Electrocardiograms Work - ECG Strips To briefly summarize the components of a normal ECG tracings, it consist of waveform components which indicate electrical events during one heart beat. These waveforms are labeled P, Q, R, S, T and U. P wave is the first short upward movement of the ECG tracing. It indicates that the atria are contracting, pumping blood into the ventricles. The QRS complex, normally beginning with a downward deflection, Q; a larger upwards deflection, a peak (R); and then a downwards S wave. The QRS complex represents ventricular depolarization and contraction. The PR interval indicates the transit time for the electrical signal to travel from the sinus node to the ventricles. T wave is normally a modest upwards waveform representing ventricular repolarization. ECG Interpretation illustration spacer image ECG Training - Introduction The focus of this introductory ECG course is to provide a tutorial about the main features of ECGs along with a method for analyzing ECGs. This method includes assessment of rhythm, calculating heart rate, observing P-wave forms, measurement of intervals and segments and the evaluation of other relevant waves. ECG practice exercises serve to reinforce the lesson content.
