What Are The 5 Lethal Cardiac Rhythms
You will learn about Premature Ventricular Contractions, Ventricular Tachycardia, Ventricular Fibrillation, Pulseless Electrical Activity, Agonal Rhythms, and Asystole. You will learn how to detect the warning signs of these rhythms, how to quickly interpret the rhythm, and to prioritize your nursing interventions.
Expert Care For This Common Type Of Irregular Heartbeat
Atrial fibrillation, or AFib, is the most common type of arrhythmia , in which the hearts two upper chambers do not beat in sync with the two lower chambers. Our patients sometimes describe it as feeling like theres a fish jumping in my chest.
A normal heart rate for adults ranges from 60 to 100 beats a minute. If you have atrial fibrillation, your heart may beat much faster, up to 100 to 175 times a minute, or much slower.
Although AFib by itself is not life-threatening, it can increase your risk of stroke and heart failure if not treated. In fact, it causes about 20 percent of all strokes because blood pools in the heart chambers and clots form.
AFib is the most common type of arrhythmia, affecting more than 5 million people in the U.S.a figure that keeps growing as the population ages. Our Cardiac Electrophysiology Program is a national leader in performing ablation procedures, such as cryoablation procedures, for AFib management. We also have the mid-Atlantics most experienced facility using the WATCHMAN device, which can prevent blood clots from forming and causing strokes in patients.

What Are The Types Of Bradyarrhythmias
A bradyarrhythmia is a slow heart rhythm that is usually caused by disease in the hearts conduction system. Types of bradyarrhythmias include:
- Sinus node dysfunction: Slow heart rhythms due to an abnormal SA node.
- Heart block: A delay or complete block of the electrical impulse as it travels from the sinus node to the ventricles. The level of the block or delay may occur in the AV node or HIS-Purkinje system. The heartbeat may be irregular and slow.

What Happens With A Normal Sinus Rhythm
Each heartbeat starts with a signal from the sinoatrial node, in your right atrium. The SA node is called the heart’s pacemaker because it adjusts your heart rate based on what you’re doing. It raises your heart rate when you exercise and slows it down when you sleep.
The signal spreads across the right and left atria. That makes them contract and forces blood into your ventricles. Then, the signal moves to the atrioventricular node node, which is near the middle of your heart.
From there, the signal travels through the ventricle walls. That makes them contract and squeeze blood out of the heart. The right ventricle sends blood to your lungs, while the left pumps it to the rest of your body. The walls then relax and wait for the next signal.
When everything is working smoothly, you have a normal sinus rhythm and your heart beats between 60 and 100 times per minute.
Arguments For Having Treatment To Restore The Heart Rhythm
If this kind of treatment is successful, it has two main advantages: On the one hand, it reduces symptoms of . On the other, the performance of the heart returns to normal. Other reasons for getting treatment to restore the heart rhythm include:
- Bothersome symptoms: For instance, if symptoms like palpitations or exhaustion don’t go away enough after treatment to control the heart rate.
- First-time, acute episode: If you have for the first time or if you havent had it for a long time. It is assumed that the chances of successfully restoring and maintaining the heart rhythm will then be higher.
- Heart failure : If it is thought that is causing heart failure, treatment to restore the heart rhythm could help to improve the hearts performance.
- If is being caused by a treatable condition: If atrial fibrillation is being caused by another medical condition, such as an overactive thyroid gland, that underlying condition is treated first. Should the heart rhythm not return to normal on its own after that, cardioversion is attempted. If treatment for the condition that is causing the atrial fibrillation is effective enough, the heartbeat often remains stable over the long term afterwards.
There are sometimes other reasons to try cardioversion for instance if the person is very sporty and finds it important to have their heart working at full capacity.

How Common Is Atrial Fibrillation
Some researchers have called Afib the new cardiovascular disease epidemic of the 21st century. Afib is especially common among older adults. Over 33 million people age 55+ have been diagnosed globally. Estimates predict that 12 million people in the U.S. will have Afib by 2030. Afib causes nearly half a million yearly hospitalizations in the U.S. and leads to more and more deaths with each passing year.
Symptoms Of Atrial Fibrillation And Atrial Flutter
A previous stroke or transient ischemic attack
Disease affecting the blood vessels
Some people without those risk factors are given aspirin, and some are not given any treatment to prevent strokes.
Even after atrial fibrillation or atrial flutter converts to normal rhythm, doctors usually continue anticoagulant treatment, often for the remainder of the persons life. This anticoagulant treatment is needed because the arrhythmia may come back without the person being aware of it. Dangerous blood clots can form during these episodes.

How Is Afib Treated
The most important step in Afib management is assessing a persons risk of stroke. For people with multiple stroke risk factors , anticoagulation medications are recommended. These drugs help prevent blood clots to lower the risk of stroke.
The second step is to slow the persons resting heart rate to 80 beats per minute. This can be accomplished with medications.
The third step involves deciding whether to control heart rhythm with antiarrhythmic medication or a medical procedure. For people who are in Afib all the time, cardioversion can restore normal rhythm. Medications or catheter ablation can then help maintain the rhythm.
Medications to control heart rate and rhythm and prevent complications include:
How Can I Reduce My Risk Of Developing Atrial Fibrillation
If you have other medical conditions or a family history of Afib, you may feel like its impossible to prevent. Its true that some risk factors cant be changed. However, the four major risk factors for Afib that we can change are obesity, physical inactivity, excessive alcohol consumption and tobacco use. Here are some tips to lower your risk:
- Limit your alcohol consumption.
- Quit smoking and using tobacco products. It can be hard to do this alone. With the right resources and support, you can achieve this goal and make your heart healthier.
As you lower these risk factors, you will also see other benefits like reduced blood pressure, lower cholesterol levels and weight loss. When it comes to heart health, each positive lifestyle change has a ripple effect. The more changes you can make, the more benefits you will enjoy in the long run.

Risks Associated With Atrial Fibrillation
The main danger of AF is the associated risk of stroke. This is present even if AF is only experienced some of the time, and whether or not the AF shows symptoms. One in every three strokes is linked to AF, and AF-linked strokes are more severe than other strokes. People with AF are also five times more likely to have a stroke compared to those who do not have AF.6
People with AF are also at increased risk of dementia. This link is independent of stroke and other risk factors, although whether the link is causal is not yet known.
What Is The Outlook With Atrial Fibrillation
Atrial fibrillation is generally not life threatening, many people live normal healthy lives with this condition, but it can be uncomfortable and often needs treatment.
This is because when the atria in the heart do not contract properly there is a risk of blood clot formation. Clots from the atria may break off and go to other parts of the body. A blood clot passing up to the arteries supplying the brain may cause a stroke.
For this reason, treatment may involve medication to control the heart rate or rhythm, and medication to prevent clots from forming in the blood.

Arguments Against Having Treatment To Restore The Heart Rhythm
The main arguments against having this treatment are the associated risks and limited chances of success:
- Associated risks: The medications that are used to restore the heart rhythm can themselves cause heart rhythm problems some of which are life-threatening. Cardioversion also temporarily increases the risk of a stroke. When the heartbeat returns to the normal rhythm, any blood clots in the left atrium might become dislodged and lead to a stroke. In the first few weeks after cardioversion there is also an increased risk of new blood clots forming in the heart. These risks can be lowered, but not completely eliminated, using preventive treatment with anticoagulants.
- Limited chances of success: Although it is often possible to restore the normal heart rhythm through cardioversion, most people develop again after some time.
- Limited advantages: Research has shown that compared to treatment to control the heart rate treatment to restore the heart rhythm doesnt increase life expectancy, and doesnt offer better protection from medical conditions caused by , such as strokes.
Treatment to restore the heart rhythm may also be less suitable
A lot of people still have to take medication to control their heart rate after cardioversion. This is because some people still have a high pulse even after the rhythm of their heart has returned to normal.
What Is Afib With Rvr
Some cases of Afib involve atrial fibrillation with rapid ventricular response . This is when the rapid contractions of the atria make the ventricles beat too quickly. If the ventricles beat too fast, they cant receive enough blood. So they cant meet the bodys need for oxygenated blood. This can lead to heart failure.

What Do I Need To Know About Atrial Fibrillation
- Atrial fibrillation is a heart rhythm problem which raises your risk of a stroke.
- AF makes you five times more likely to have a stroke. If youre diagnosed with AF, youll have an individual stroke risk assessment to make sure you get the right treatment and advice for you.
- Strokes due to AF tend to be more serious, with more damage to the brain and worse long-term effects. So if you have AF, youll be offered any treatment you need to reduce your risk of a stroke.
There are different types of heart rhythm problem , and atrial fibrillation is the most common. Around 1.4 million people in the UK have AF. Its a major risk factor for stroke, and around 20% of all strokes are caused by AF.
Can I Control An Afib Attack At Home
I highly recommend that all people diagnosed with AFib discuss at-home symptom management strategies with their primary provider. During mild attacks, it is possible for a person trained in symptom reducing techniques to manage their symptoms without the need for medical intervention.
Things like regular baseline assessment, heart rate monitoring, and at-home ECG devices can be very helpful for those living with atrial fibrillation. For more information about at-home options for managing AFib, please read my article about four common ways to stop an AFib attack.

What You Can Do To Stabilize Your Heart Rate
If youre in an emergency situation, the best way to stabilize your heart rate is to seek immediate medical attention.
In a non-emergency situation, consider exploring stress-relieving tools like mindfulness and meditation, modifying your diet and incorporating more movement into your daily routine. One of the most common and effective ways to stabilize your heart rate is to exercise consistently. Meanwhile, eating a heart-healthy diet, such as the Mediterranean diet, can also help stabilize your heart rate.
Spending time in nature is an underrated way to help stabilize your heart rate, according to John La Puma, M.D., the clinical director and founder of Chef Clinic in Santa Barbara, California. Even looking at nature can relax your physiology, he says. Real nature has mixed effectsfor some people, it relaxes you, and for others, it excites you. Either way, nature-based therapies are important heart health tools.

Related Conditions Of Atrial Fibrillation
Atrial fibrillation is a type of arrhythmia, or irregular heart rhythm. Other arrythmias include:
Atrial Flutter This condition is similar to afib, except the rhythm in the hearts upper chambers is somewhat more organized. Atrial flutter can become atrial fibrillation, and vice versa.
Supraventricular Tachycardia This broad term refers to many arrhythmias that can develop above the hearts lower chambers, which may cause episodes of heart palpitations that start and end suddenly.
Ventricular Fibrillation This condition is similar to afib, but affects the hearts lower chambers . Since these chambers pump blood to the entire body, its extremely serious and can be fatal if normal rhythm isnt restored within a few minutes.
Long QT Syndrome This heart disorder carries a risk of fast, chaotic heartbeats, which may cause fainting and may be life-threatening, according to the Mayo Clinic.
