[torturing-characters-101]

Let's say a character with some sort of crazy hearing/sensory enhancements has the ability to pick up on the sound of someone's heart beat. If they had this ability... theoretically, would they be able to hear a heart attack before the person felt it? What would it should like? How much notice would they be able to provide??

Ooh, really good question, anon.

The answer is... potentially.

In order to explain why, we have to talk a little about what hearts sound like to the people who are trained to listen to them.

A healthy heart has 2 sounds per beat- Lub and Dub, also called S1 and S2. You can hear this in your own heart or a friend's if you have a stethoscope (or just an ear you can press against a friend) and listen at one of these locations:

You'll hear a heart that probably sounds like Lub-Dub Lub-Dub Lub-Dub, etc... The Lubs are S1 and the Dubs are S2. One Lub-Dub (S1-S2) cycle is a single heart beat.

But there are other sounds that can be heard if someone has a problem with their heart. For example, if one of the heart's 4 valves has a leak in it, you might hear a "Shhh" sound somewhere between or around the Lub and Dub. Like Lub-Shhh-Dub or Lub-Dub-Shhh. Depending on which part of the chest the "Shhh" sound is audible, you can tell which valve is faulty.

You might also hear an S3 or S4 sound. S3 and S4 are "extra" sounds that occur during the heart cycle. An S3 sound is like a "Uhh" and happens at the end of the Dub (Lub-Dub-Uhh). An S4 sound sounds like a "Buh" and weirdly enough happens before the Lub (Buh-Lub-Dub).

For the purpose of your question what we really want to focus on is that S4 sound. This is a sound that almost universally occurs in the early stages (first 1-3 days) of a heart attack.

See, the S4 sound is the sound of the top of the heart (atrium) straining as it tries to push blood into a damaged, overgrown, or swollen lower part of the heart (ventricle). Since heart attacks cause damage to the ventricle(s), you get this sound pretty soon after the damage starts occurring. You can even tell where the damage is in the heart (left or right) by where on the chest you hear the S4 most clearly.

But since heart attacks are not the only reason for damage to the ventricle, hearing an S4 sound does necessarily mean that a heart attack is currently occurring. It could have been that the person has had a heart attack in the past and they have scarring on their ventricle(s). It could also mean that they have had high blood pressure for a long time and their left ventricle is bigger and stiffer than it is supposed to be. It could be that they have heart failure and there is more pressure in their ventricles than there should be. It could be that they had an infection in their heart that left scarring in the past. It could be a problem they were born with.

Since these are all chronic problems, what your character would have to notice is a sudden start of an S4, probably combined with other symptoms. When the S4 sound starts, these symptoms might not be the "classic" heart attack symptoms yet. They might be feeling "off" or more out of breath than usual, or more tired than usual, or they might have some mild nausea or indigestion.

Your character might be able to provide at least a few hours of notice before the more classic symptoms show up.

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.

(sorry if this already got sent, my browser died while I was trying to send the ask)

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.

Marriage Equality Achieved!

Today, January 23, the marriage equality law officially takes effect. Thailand now recognizes the right of all couples, regardless of gender, to legally register their marriage.

At 6.15am, the first couple, 33 year old Ploynapas Jirasukon and 32 year old Kwanporn Kongphet arrived, hand in hand, to register their marriage. Together for 17 years since high school, the Bangkok-based couple radiated joy as they became Thailand’s first officially recognised LGBTQ+ married couple.

Ploynapas shared her excitement, “We’re thrilled to be the first couple to register our marriage. It’s a proud moment, but there’s still more to achieve, like equality in child custody and legal titles.”

Sumalee, 64, and Thanaporn, 59, became the first same-sex couple to register their marriage at Bang Rak today.

Traveling all the way from Phetchabun, they chose Bangkok's "district of love" for this special occasion.

Permsap and Puangphet, the second couple to register their marriage in Pathumwan District, shared that they had waited 17 years for this moment, calling it a meaningful achievement.

Although they could have registered in Pai, they chose Pathumwan to express pride in exercising the same legal rights as other Thais. They wore traditional Tai Yai attire from Mae Hong Son, reflecting one partner's heritage, to make the occasion special.

They described the milestone as a collective success for the LGBTQ+ community, achieved through shared efforts.

They hoped future legal changes would address honorific titles for transgender individuals, ensuring fairness for all. The couple encouraged others to stay determined in the fight for equality, believing that persistence leads to success. They also urged countries without equal marriage laws to continue advocating for change.

Reflecting on a past accident, they shared the difficulties caused by the lack of legal recognition. Despite being together for eight years at the time, one was unable to sign medical consent due to the law, underscoring the need for equal marriage rights.

I think my heart is still going haywire. Any tips on how to stabilise heartbeat?

[st4rw31rd0]

FUN FACT!!!

I was born with a weak heart what healed. I don't have a heart condition like CHD, AFib, ect. But my mom calls it "a shake in the heart"

So basically my heart was born with some missing nutritions, the doctors said that due to this i would either have to get surgery or i would have to stay in the hospital and wait to get the proper amount of nutritions my heart was missing, my mother waited and i earned those nutritions, therefore, im ok!
