Hi, I was wondering if it's feasible for someone playing football (soccer, not american football) to get commotio cordis if the ball hit them in the chest? I can find one or two case studies of it but would this be just too rare?

It's definitely possible, especially for a younger athlete.

Commotio Cordis is a condition in which an impact to the chest causes sudden cardiac arrest in the form of a heart rhythm called ventricular fibrillation. It is pretty rare, happening about 30 times per year, mostly in people younger than 20 years of age.

Most commonly, it happens in baseball, but it can in theory happen any time there is a blow to the left side of the chest hard enough at the exact wrong point in a heartbeat. The rarity comes from the fact that this "wrong point" occurs for less than 1/100 of a second per heart beat. In order to hit someone's chest hard enough, the ball would have to be traveling about 40mph, and make contact at that precise moment.

Soccer balls can be kicked as fast as about 60mph, so it would absolutely be possible.

Commotio cordis has about a 50% survival rate when treated immediately with CPR and an AED, so it has a very high survival rate compared to other reasons for cardiac arrest.

Regardless of it's rarity, it's pretty well known, so using it in a story wouldn't look particularly weird. And since there is actually a 50/50 chance of survival, it wouldn't be too odd that the person survived.

hii! what are the effects of prolonged tachycardia with fluctuating bpm ranging from 140-160 for around 30 minutes to a conscious patient? will it cause any brain damage?

The short answer is basically nothing and no.

Tachycardia is any heart rate above 100 in an adult. There are several different kinds of tachycardia, including sinus tachycardia, paroxysmal supraventricular tachycardia, atrial fibrillation with RVR, and ventricular tachycardia. Whether the tachycardia is bad for a person has to do with what kind of tachycardia it is, what the heart rate is, and how long the person is in that rhythm.

The first one we'll talk about is sinus tachycardia. Sinus tachycardia is a normal physiological response to the body's demand for more oxygen and nutrients. Sinus tach happens when someone has a fever, is dehydrated, has blood loss, is in shock, or is having a strong emotional response.

It's one of those things that doesn't need treated in and of itself, though figuring out and treating the cause is important. Once the cause is treated, the heart rate usually drops back down to normal.

There are also times when you intentionally bring the heart rate up above 100- for example, exercise. This is also considered sinus tachycardia. When you exercise, you want your heart rate to be in a target zone, which depending on age can be anywhere from 75-170bpm (the younger you are, the higher the target heart rate).

In the case of exercise, a heart rate of 140-160bpm for a half hour would be completely reasonable. In the case of dehydration or shock, you'd really need to fix the problem, but the heart rate itself isn't going to hurt anyone under about 60 who is otherwise healthy.

Paroxysmal Supraventricular Tachycardia (PSVT) is a condition in which the heart rate randomly increases into the high 100s-low 200s. This heart rate is so fast that the heart doesn't have time to fill with blood in between beats. Because of this, not as much blood is getting out of the heart to the brain and body, which means the person may feel faint, short of breath, or dizzy or even pass out.

People in PSVT may spontaneously convert back into a normal rhythm, or they may need a drug called adenosine given to change them back to a normal rhythm. Adenosine works kind of like a defibrillator- it briefly stops the heart in order to let it restart normally. If this happens frequently, someone may need an ablation- a procedure in which parts of the heart muscle that are causing the rapid heart rate are burned to permanently prevent future attacks.

In order to understand atrial fibrillation with RVR, you have to understand how the heart initiates beats normally. In the heart there are cells in a place called the SA pacemaker node, which send out small electrical signals that work to coordinate a beat across all the cells in the heart.

In atrial fibrillation, lots of cells outside this node try to initiate beats, which causes the top half of the heart to quiver. If a lot of these "beats" get through to the bottom of the heart, that's called Rapid Ventricular Response, or RVR. Afib RVR causes a rapid, irregular heart rate.

Afib RVR can cause the same problem as PSVT- namely that it causes the heart to beat so fast it can't refill with blood in between beats. Usually the first few times this happens the person converts out to a normal rhythm within about a week (or can be converted out with defibrillation or medications). Later this state can become permanent and has to be managed with medications that reduce the heart rate and blood thinners to prevent strokes and heart attacks, which happen because blood gets stuck and clots in the quivering upper part of the heart.

The last one, ventricular tachycardia, is the most dangerous because if not treated it can either become so fast virtually no blood is coming out of the heart (cardiac arrest) or become another dangerous rhythm called ventricular fibrillation (also cardiac arrest, but even worse).

This one is a life-threatening emergency and needs to be treated immediately with CPR (if the person is unconscious) defibrillation and medications.

This was a lot to answer your question, but all this to say that if your person is running 140s-160s because they're working out for a half hour, they're totally fine. If they're 140s-160s because of PSVT they're not fine but they're probably going to convert out of it with a medication or just time. If they're 140s-160s in RVR they're probably uncomfortable and need medical attention but they'll probably be alright. If they're in ventricular tachycardia, they need emergency care.

Of these, the only one that could really cause brain damage is the ventricular tachycardia, but it would have to be a lot faster than 140-160.

question for anyone with anxiety who experiences the fast heartrate and chest pain symptom

do you ever experience that before going to sleep or when waking up at times when you're otherwise relatively calm?

I'm asking cause that's been happening to me recently and I went to a doctor and got a heart monitor to get it checked out and they said the results were normal and I probably have anxiety. Think is it's not unreasonable to believe I do have anxiety, and I definitely do get increased heart rate for stress and adrenaline and caffeine reasons too, but those are all times I'm relatively stressed or over-excited and it's been happening when I'm relatively calm and literally like taking a nap.

I'm having a very hard time figuring out if this is medical gaslighting or not so I'd very much appreciate if anyone has any input on whether or not this could be an anxiety thing or other possible reasons this could be happening.

Thank you

I hope you get together soon,Cowboy. You looked so happy and I wish you all the best.

Previous anon-go through her previous posts-she and her gf did pretty well together. Respect it.

Thank you. We say we are "unwillingly single". She is the most amazing woman I have ever met and whether that is my heart's biasis talking or not she is just not someone I care to "get over" right now, perhaps never. The future is what it will be.

We are the best of friends. We agree we are each other's person and we are working hard (but it kind of comes easy) to strengthen our friendship and balance the heart ache.
