How Does a Healthy Heart Work

Your heart is a muscular organ that pumps blood throughout your body. It’s about the size of your fist and sits in the middle of your chest.

The heart has four chambers: two atria (upper chambers) and two ventricles (lower chambers). Thick walls of muscle separate the chambers. They contract and relax in a coordinated way to pump blood.

Valves between the chambers open and close with each heartbeat. They prevent blood from flowing backwards.

The rhythmic contractions of your heart keep blood moving through your body. Your heart is a muscular pump that works nonstop for your entire life.

The average heart beats about 100,000 times a day. That’s about once every second!

Your heart also works as a team with your lungs. They share the important job of getting oxygen-rich blood to all the parts of your body.

The human heart is an amazing organ. It’s about the size of your fist and weighs around 10 ounces. This hard-working muscle pumps blood throughout your body 24/7. In an average lifetime, it will beat more than 3 billion times!

Your heart is located in the centre of your chest, slightly to the left. It sits behind and between your lungs. The heart is surrounded by a thin membrane called the pericardium.

The heart has four chambers: two upper chambers (the atria) and two lower chambers (the ventricles). There’s a wall of muscle separating the left and right sides of the heart (the septum).

Blood enters the heart through two large veins: the vena cava (upper veins) and the pulmonary veins (lower veins). The atria contract and force the blood into the ventricles. The ventricles then contract and push the blood out of the heart and into the arteries.

The right side of the heart pumps blood to the lungs, where it picks up oxygen. The left side of the heart pumps oxygen-rich blood to the rest of the body.

The heart pumps oxygen-rich blood to the rest of the body. The left side of the heart receives oxygen-rich blood from the lungs and pumps it to the rest of the body. The right side of the heart pumps oxygen-poor blood from the body to the lungs.

A-FIB VERSUS JUNCTIONAL RHYTHMS

. ATRIAL FIBRILLATION: On your rhythm strip, the two most important characteristics are: . 1) A rhythm that’s IRREGULARLY irregular (meaning there’s no way to predict the next beat) 2) No discernible P waves . In fact, if you notice an irregularly irregular rhythm and you’re having to convince yourself that you see P waves... it’s probably A-fib (multifocal atrial arrhythmias like WAP/MAT could fit the differential) . *In my opinion: Don’t get caught up in using fibrillation waves as an absolute criteria. Very fine A-fib can sometimes produce a near isoelectric line between beats. . JUNCTIONAL RHYTHMS: The pacemaker cells surrounding the AV junction are capable of initiating regular impulses but at a slightly slower natural rate than their sinus and atrial superiors. The heart is built this way so that when the pacemaker cells with the fastest intrinsic rates are in action, those below are suppressed and function primarily to pass along the impulse from above. . For these reasons, we s

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

What is The Cardiac Cycle ?

The cardiac cycle refers to the sequence of events that occur and repeat with each heartbeat. It can be divided into two main stages: Systole and diastole, each of which is divided into several small steps When systole and diastole are not specified otherwise refers to ventricular contraction and relaxation Respectively, Reminder Blood flows from low to low pressure Compression increases the pressure in a Chamber, while relaxation reduces the pressure. When the AVT valves open the anterior pressures are higher than the ventricular pressures and Off when the pressure gradient is reversed. Similarly, Semiluna valves open when ventricular pressure exceeds submerged /, pulmonary pressure And stop. If the opposite is true, The cycle was started by firing shots at the SA node, which encouraged the atria to lower .
