How Does Cold Weather Affect Atrial Fibrillation?

How Does Cold Weather Affect Atrial Fibrillation?


We're going to be discussing cold weather and atrial fibrillation and see how cold weather can actually affect a person's atrial of fibrillation. It's winter time now in the United States and there are several articles in the past that have discussed how cold weather can actually affect a person's atrial fibrillation. Now first does cold weather actually affect people getting episodes of afib, do people get more frequent episodes of afib during the winter time? There was a review article which came out of 2015 which showed, yes. They actually reviewed up to 15 different studies and the amount of increase for afib and the increase in hospitalizations ranged anywhere from 200 to up to 300% increase in the amount of afib hospitalizations during the winter time, depending on which individual study that that one study reviewed in.

In addition that same study also found an increased risk of stroke for people who have afib during the winter time periods, when in that risk of stroke came from anywhere from 20% all the way to 200 percent increased risk of stroke. There was also an additional study in 2018 recently published which showed also an increased risk of stroke for patients during the winter time periods and that risk of stroke in that study went up to almost 20% increased risk of stroke during the winter time periods. So why did this all happen first? Why do people get episodes of afib during the winter time? There is there's no real clear answer to that one it's unclear if the cold by itself affects the person's atrial fibrillation, it's not very clear whether it's just the temperature itself is what can cause atrial fibrillation or increased episodes of afib. However that what is more commonly associated with the winter time that can trigger episodes of afib are the increased illnesses that happen there in a winter time such as colds, flus, pneumonias also people who have respiratory problems like COPD or emphysema are most likely to exacerbation that disease during the winter time.

So in the winter time is probably more likely because of people getting sick for other reasons you get a cold you get a flu or pneumonia which are much more common in the winter months and that can certainly increase a person's risk for getting episodes of atrial fibrillation and also hospitalizations for afib. But as far as the increased risk of stroke I mentioned two studies that increase the show that increased risk of stroke during the winter time and why is that? There are some theories that the small little clotting proteins that are in your blood which help clot your blood that your body produces more of them during the winter time to help kind of keep your blood from being too thin or have making your blood thicker and that may increase your risk of stroke during the during the winter time.

So during this winter what are my tips to you in order to try to maintain a safe winter time. Obviously stay warm or wear layers minimize time outside in the extreme cold as best as possible and obviously try to minimize sick contacts as many people are going to be sick with colds and flus during the winter time and try to minimize sick contacts. But hopefully with these few tips you can have a healthy winter season thank you.

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. . . . đŸ’™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 .
