Are all heart beat irregularities dangerous? What makes your heart skip a beat?

  Abnormal heart rhythms can be dangerous or not dangerous than ones that aren't dangerous. Things are usually just little extra beats and your heart is quite unique. It can generate electricity anywhere through its entirety, and sometimes that manifests is just little extra beats. Sometimes they don't even feel it and it's just picked up in other ways. Often those kinds of things is not dangerous at all. The dangerous heart rhythm is usually seen in association with structural or functional problems in the heart. There'S also another group of rhythms that can occur usually due to changes in genetics. So the way your heart's put together electrically is not normal and the heart can't be otherwise very normal in that situation, but people can still be at risk of having life-threatening heart rhythm disturbances. So when people have an arrhythmia, sometimes they have symptoms. The symptoms can range from simply a sense of skipping them extra beats. Sometimes they ...

The Pathway of Blood

Here’s a great illustration on the pathway of blood flow through the heart. It may seem easy...but you should know this cold as well as the cardiac anatomy, both of which will make procedures and understanding hemodynamics easier. . . . 💙VENOUS BLOOD- Blood flows into the heart (into the right atrium) through two major veins (the superior and inferior vena cava) as well as from the coronary sinus (cardiac venous blood from the coronaries) and then out through the first AV valve (tricuspid valve) into the right ventricle. From there blood flows into the right ventricular outflow tract, across the first semilunar valve (pulmonic valve) and into the main and then left and right pulmonary arteries. Blood then enters the lungs to become oxygenated. . . . ❤️ARTERIAL BLOOD- now that blood is oxygenated flow goes from the lungs into the left atrium through 4 veins (usually) called the pulmonary veins. From the left atrium blood flows across the other AV valve (mitral valve) and into the left ...

Cardiac Structures Visualized From Within The Heart

  Take a trip inside the heart ! . . . 🎦Here’s a great video of the cardiac structures visualized from within the heart. . . . The heart is composed of 4 major valves . . ♦️The AV valves: Mitral and Tricuspid . . 🔹The Semilunar Valves: Aortic and Pulmonic . . . 💞The aortic valve is made up of three major cusps: the right, left, and non coronary cusps. The pulmonic valve is made up of the right, left, and anterior cusps. The mitral valve has two leaflets: the anterior and posterior leaflets. The tricuspid valve has three leaflets: the anterior, posterior, and septal leaflets. The mitral and tricuspid Valves have subvalvular apparatuses with papillary muscles and chordae. . . . 📝Keys about the heart valves: . . 🔑 they are collagenous, non conductible tissue, that form the fibrous trigone of the heart . . 🔑 the tricuspid valve always names the morphological right ventricle and (for the most part) is always apically displaced . . 🔑 the mitral valve is the only AV valve that shar...

Interactions between heart disease and kidney disease

There are a number of important interactions between heart disease and kidney disease. The interaction is bidirectional, as acute or chronic dysfunction of the heart or kidneys can induce acute or chronic dysfunction in the other organ. The clinical importance of such relationships is illustrated by the following observations: ●Mortality is increased in patients with heart failure (HF) who have a reduced glomerular filtration rate (GFR). ●Patients with chronic kidney disease have an increased risk of both atherosclerotic cardiovascular disease and HF, and cardiovascular disease is responsible for up to 50 percent of deaths in patients with renal failure. Consult with  cardiovascular doctor  with chronic kidney diseases. ●Acute or chronic systemic disorders can cause both cardiac and renal dysfunction ●Type 1 (acute) - Acute HF results in acute kidney injury (previously called acute renal failure). ●Type 2 - Chronic cardiac dysfunction (eg, chronic HF) causes progressive chron...
