Can a ball hit in the chest cause the heart to stop suddenly? Let's learn exactly about Commotio Cordis!

Have you ever heard of someone being hit in the chest by a fast-moving ball while playing cricket or any other sport? This is really scary, isn't it? Most of the time we think it's just a minor bruise. However, in rare cases, it can be a very serious condition that can be life-threatening . Today, we are going to talk about a very rare, sudden, and specific heart condition. This is called `Commotio Cordis` in medical terms. This means ``a disturbance of the heart'' in Latin.

What is `Commotio Cordis`? Simply put...

Simply put, `Commotio Cordis` is when a blow to the heart, at a specific point, at a specific moment, from a small, hard object (often a baseball or hockey puck), suddenly changes the normal rhythm of the heart, causing an abnormal heartbeat (`ventricular fibrillation`) and causing the heart to suddenly stop beating (`cardiac arrest`). Imagine, our heart is a very complex and very orderly organ. It beats according to a specific electrical signal system. In this `Commotio Cordis`, the electrical activity of the heart is disrupted at a very critical moment due to the impact of that external blow. This is like a well-functioning machine suddenly receiving a blow from the wrong place, disrupting its functioning.

How common is this condition called `Commotio Cordis`?

In fact, this is a very rare condition. Don't be alarmed. Even if you look around the world, less than 30 cases of `Commotio Cordis` are reported per year. So this is not a disease that affects everyone. However, even though it is rare, the damage it can cause is serious, so it is very important to be aware of this.

Can someone survive a condition called `Commotio Cordis`?

Yes, it definitely can! But it requires immediate medical attention . If someone is knocked to the chest like this and falls, it is very important to immediately perform `CPR` (Cardiopulmonary Resuscitation) and `defibrillate` the heart using an `AED` (Automated External Defibrillator).

Fortunately, as people have become more aware of this condition over time, the chances of survival have increased significantly due to the increased use of CPR and AED machines.

What are the symptoms of this condition?

The main symptoms of `Commotio Cordis` are:

• Pulling and falling as soon as you get hit in the chest. This is the main thing.
• An abnormal heart rhythm (`Ventricular Fibrillation`). This means that the lower chambers of the heart simply quiver instead of pumping blood properly.
• Sudden cardiac arrest (Cardiac Arrest).
• Loss of consciousness.

These symptoms come on suddenly. There may be no signs at first.

What causes `Commotio Cordis`?

For this condition to occur, several factors must come together. The main cause is a blow to the left side of the chest, right where the heart is, usually from a small, relatively strong object, such as a baseball, lacrosse ball, or hockey puck, at a 90-degree angle, at a speed of about 40-50 miles per hour. Think of a fast-moving leather ball when playing cricket, or any other sports equipment that hurts if it hits the body. But this does not happen with every blow. The most important thing is the time when this blow occurs. There is a very specific, very small period of time in our heart's `cardiac cycle`, a time when the lower chambers (`ventricles`) of the heart contract, pump blood, and then relax again. That is the very moment when this blow should occur. Then, due to the impact of that blow, the heart muscle, which should be relaxed, can suddenly become stimulated, leading to the previously mentioned `ventricular fibrillation` condition.

Can a punch cause a `Commotio Cordis`?

Yes, theoretically it is possible. But for that, all the conditions mentioned earlier have to be met. That is, the blow has to be to the left side of the chest, at a 90-degree angle, at a speed of 40 miles per hour or more, and at that precise moment in the heart. The chances of this happening with a blow delivered in a normal fight are very low.

Who is at higher risk of `Commotio Cordis`?

Although this condition can happen to anyone, some people are at higher risk:

• For those who play sports: Especially for those who play sports that use hard balls or equipment, such as baseball, lacrosse, softball, hockey. In our country, it is good to be careful about this in cricket as well.
• For young people under the age of 20: This condition usually affects people around the age of 15. This may be because the chest bone system of young people is not yet fully mature, making it more likely that the shock of a blow will be transmitted to the heart.
• For males: This is more common among boys than girls. This may be because boys often engage in more contact sports.

What are the complications of `Commotio Cordis`?

The main and most dangerous complication of this is sudden death from heart attack.According to the National Cardiovascular Registry, more than 220 people have died from this condition since 1996. Therefore, this is not something to be taken lightly.

How to recognize `Commotio Cordis`?

If someone, especially a young person, is struck in the left side of the chest while playing sports and suddenly falls, a doctor may suspect `Commotio Cordis`. However, this is a `diagnosis of exclusion` . This means that doctors first look to see if there are other common causes, such as a heart attack. If there are no such causes, they think `Commotio Cordis` may be the cause. After providing immediate `CPR` and `defibrillation`, the following tests may be done in a hospital:

• Electrocardiogram (EKG): Checks the electrical activity of the heart.
• Blood tests : To check for heart damage or other problems.
• Echocardiogram: A scan to look at the structure and function of the heart .
• Heart MRI or CT scan : Get clearer images of the heart.
• Heart catheterization: A test to check for things like blockages in the blood vessels of the heart.

How is `Commotio Cordis` treated?

Immediate medical attention is essential for a person experiencing `Commotio Cordis`. If you see such an event, immediately call 119/1990 and start `CPR` yourself. If possible, quickly find an `AED` machine and use it. After providing emergency treatment, the patient is admitted to the hospital and a complete examination is done to check for any other undiagnosed heart conditions. In the hospital, the heart's function is monitored.

Specific treatments

If an adult patient with `Commotio Cordis` is unconscious and unable to follow commands, doctors may use a treatment called `therapeutic hypothermia`. This involves sedating the patient, inserting a breathing tube, and lowering the body temperature to 32-34 degrees Celsius (89.6-93.2 Fahrenheit) for about 12-24 hours. This is done using special cooling machines, ice packs, frozen `IV` fluids, and cooling blankets. This helps reduce the rate at which oxygen is used by the brain and prevents swelling. Then, the body is slowly rewarmed over several hours.

Side effects of treatments

Treatments like `therapeutic hypothermia` can sometimes cause side effects. For example:

• `Pneumonia`
• Sepsis (blood poisoning)
• Abnormal heartbeat
• Coagulopathy (decreased ability of blood to clot)

How to reduce the risk of `Commotio Cordis`?

While this cannot be completely prevented, there are things you can do to reduce the risk:

• Wearing protective gear: Wearing chest protectors can provide some protection. However, there have been cases of 'Commotio Cordis' even when these were worn.
• Safe sports equipment: Using things like ``softer baseballs'', especially designed for young players.
• Awareness and preparation (this is the most important thing!):
• It is essential that coaches, teachers, and sports staff are trained in how to recognize `Commotio Cordis` and how to perform `CPR`.
• We need to ensure that sports venues have easily accessible, well-functioning AED machines.
• Having a well-planned and practiced Emergency Action Plan (EAP) is essential for prompt treatment.

Imagine, how much of a relief it would be if there was an `AED` where your child plays, or where you play, and someone who knew how to use it.

What to expect if you experience `Commotio Cordis`?

If doctors examine you and confirm that there are no other problems with your heart, you will not need any further treatment after recovering from `Commotio Cordis`. However, if they discover that you have a previously unknown, congenital or genetic heart condition, you will need to receive treatment for that.

Can I start playing again?

After your heart has been fully examined, including an EKG, Echocardiogram, MRI or CT scan of the heart, and a stress test, you may be able to return to playing sports. However, if your doctor sees any problems with your heart, or if there is a slight or significant risk of a recurrence of Commotio Cordis, you may be advised to avoid sports that involve impact that could damage your chest.

What is the future outlook for the `Commotio Cordis` situation?

`Commotio Cordis` is the second leading cause of sudden cardiac death among young athletes. The first is `hypertrophic cardiomyopathy` (hypertrophic cardiomyopathy). If treated promptly, the survival rate is about 59%. That means more than one in two people can be saved. However, those who do not receive `CPR` quickly, or those who have congenital heart disease, have a lower chance of survival.

How do I take care of myself?

If your cardiologist says there is nothing wrong with your heart, you may not need follow-up care. However, if they find a heart condition that you were not aware of, you should definitely get it treated. Even if you have no heart problems, it is a good idea to have a checkup at least once a year.

When should I go to the emergency room (ER)?

If you have a diagnosed heart condition, you may need emergency treatment again. If you experience any of these symptoms, tell someone nearby to call 119/1990 immediately:

• Chest pain
• Feeling like your heart is beating fast (`heart palpitations`)
• Shortness of breath
• Lightheadedness
• Passing out

What questions should I ask my doctor?

You can ask the doctor questions like:

• Do I have any heart conditions that require treatment?
• Can I play competitive sports again?
• What should I do to prevent further damage to my chest?

Being hit in the chest is a traumatic experience. However, the chances of survival after `Commotio Cordis` are much higher today than in the past. With prompt medical attention, most people can recover. If your doctor diagnoses you with a heart condition, follow their instructions exactly. `CPR` training and the availability of `AED` machines can bring great peace of mind to those who participate in sports that are at risk of `Commotio Cordis`.

Take-Home Message

Okay, so I hope you have a good understanding of the `Commotio Cordis` we talked about today. Remember, this is a very rare occurrence, but it can be very dangerous if it happens.

The most important thing is, if someone is suddenly knocked down by a blow to the chest while playing sports, don't take it lightly. Immediately provide emergency medical assistance (CPR, use of an AED, hospitalization).

As coaches, parents, and players, staying aware of this, getting CPR training if necessary, and checking for AEDs at sports venues can help save lives. Let's play safe, stay healthy!
