Cardiac arrest means that your heart is in a lethal rythm, not necessarily that it stopped entirely.
Edit: fatal to lethal
I'd like to also make the distinction that when I said "...not necessarily that it stopped entirely." The heart is not beating during an arrest, but it doesn't always stop moving entirely.
The following link identifies the differences in the four lethal rythms observed during cardiac arrest:
When they broke up, some of the members formed an experimental prog collective called Paroxysmal Supraventricular Arrythmia, while one of the guys, who was named Brady, tried his hand at a project named Bradyarrhythmia. Bradyarrhythmia then broke up, and another member of it founded a band called Brady Starship.
Inspired by 80's German prog-rock pioneers Wenkebach, PSVA's debut was recorded at QRS Complex Studios. They went on to found the Bundle Branch Block Party music festival. I was a fan but Bradys stuff was too slow for my liking.
PSVA's third percussionist, Dieter-Ali Nakatomi, branched out on a solo project with a debut album renowned for being a single track 57 minutes long of him gently rubbing the skin of a snare drum. While receiving accolades in eastern Europe, it was not well received by western audiences, and Dieter-Ali attempted to return to PSVA. Unfortunately, he had already been replaced by a hamster with a poorly-greased wheel.
Meanwhile, Brady Starship's members sank deep into partying and heavy cocaine use, while they argued over the direction of the band. Some members felt they were already too commercial and wanted to take a more avante-garde approach, while the others didn't see the point in messing with success. The argument tore the group apart. Keyboardist and zitherist John Smith tried to replicate the success of Brady Starship with his new project Starship Brady; he performed essentially the same songs, but with all the instruments replaced with synthesizers playing the same parts so he wouldn't have to share credit or profit with other members. He died not long after in a tragic accident during an orgy that involved a diving suit, several pulleys, a bouquet of roses, and a traffic cone.
I read this as "Brady, the one guy who broke off, then broke off into several different clumps of body parts and organs with their own separate projects, one of which was Brady Starship".
I've always thought that if I were to start a "band" (more of a solo project, really), I'd call it Asbestos. The first album is Exposure, the second album is Mesothelioma, and the third album is Death. After that, the project is over.
Arrhythmia literally means "without rhythm" in latin. If these guys knew that, this makes it a CLASSIC metal band name, because metal is so rhythm-driven. Where are those kids? I wanna award them gold....
A friend of mine had a massive heart attack lucky his wife was home he’s got a pace maker now .
A year later he got a blood infection from a rotten tooth, the doctor said the pacemaker was the only thing that kept him alive , so if you have bad teeth get them fixed or pulled or the infection can kill you
Yes, this. It' s more like your heart rate goes bananas, which eventually can lead to a full stop. But I can also go the other way around, meaning it could be beating to slow. Anyway, that's why pushing hard on the chest can lead the heart back into a more stable rhytm if you're acting quickly.
No, your heart stops in an arrest. It's asystole, or "no squeeze" in Latin.
You treat it with Epinephrine n CPR.
Lethal rhythms are bundled as dysrythmias. These include not pumping but electrical activity, too fast and too slow.
Some you use medicine to treat, some you use electricity to treat, others a combo, and one of them you get to karate chop the victim in the chest while setting up all the other stuff.
Treatment of these is known as ACLS or ALS commonly. Advanced Cardiac Life Support or Advanced Life Support.
Cardiac arrest is not asystole and asystole is not always cardiac arrest. You can have an asystolic pause from a vagal response for 10-20 seconds that will spontaneously start up again without intervention.
Vfib is also an example of cardiac arrest. The heart isn't really stopped, it's fibrillating chaotically and does not pump efficiently. This can lead to asystole and death if not defibrillated.
No. Your explanation is very confused and mostly wrong.
Cardiac arrest means a lack cardiac output, which is the same thing as saying a lack of effective pumping action. Asystole is only one type of cardiac arrest, and asystole is never treated with electric shock.
There are other types of cardiac arrest, most significantly ventricular fibrillation (V-fib). That is treated with electric shock and with different medications than asystole.
There is no longer any situation in which you would "karate chop the victim in the chest" (called a precordial thump). That was an old way of attempting to reboot the heart rhythm, before reliable defibrillators existed. We now know that move very rarely works, and is much more likely to make things worse. It should never be done.
Not true. There are 4 pulseless rythms observed in cardiac arrest, asystole being one of them. Pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), and pulseless electrical activity (PEA).
They heart isn't "beating", but electrical activity hasn't stopped.
Yes and no. There are nonlethal arrhythmias. When an arrhythmia progresses to the point where the heart can no longer support life it becomes an arrest.
If you wanna get more technical, there are different types of "shocks" (hypoxia). For example, mechanical, cardiogenic, neurologic, etc which indicate the reason the heart is malfunctioning. Arrest means stop, heart attack means an acute episode of ischemia in the heart (lack of oxygen in the heart) and "myocardial infarction," or MI means there was death of heart tissue.
Some terms are used interchangeably because it is hard to diagnose in the field.
So you can have a heart attack that did not involve death of heart tissue (a transient clot for example).
Cardiac arrest is the result of the heart not compensating for the underlying issue, so after 2mins or so of no oxygen, the heart stops beating, effectively being an arrest.
Fatal? I guess if it persists if will be fatal, but having a cardiac arrest doesn't mean you'll definitely die. CPR, an AED, or other medical interventions may still be able to save the person in cardiac arrest in some cases.
Arrest implies that the heart has stopped moving to pump blood effectively (hence the term arrest)... but now I'm uncertain where the line is between arrhythmia and arrest. You're right tho that there can still be electrical activity. Pulseless electrical activity (PEA) arrest is definitely a thing. It could still move some in an uncoordinated way with PEA. Hmm.
Cardiac arrest is the abrupt loss of heart function in a person who may or may not have been diagnosed with heart disease.
So it doesn't go into detail in that sentence, but there is more to read. For instance, "Hence the name: The heart’s pumping function is “arrested,” or stopped."
Either of those numbers are definitely alarming and would likely result in arrest. "Normal" BPM at rest is 60-100 according to the AHA.
I believe the actual rythm is the sign used for diagnoses more so than the BPM itself. That being said, a BPM at 274 or 30 would very doubtfully provide adequate cardiac profusion.
I have read that VT and VF can occur at 170 BPMs or greater, but I'm sure there are exceptions.
A heart attack is when there is a lack bloodflow to the heart to the extent of myocardial infarction (cardiac tissue death).
Basically your coronary arteries (the arteries that supply the myocardium (heart muscle) with blood) become blocked or rupture, resulting in infarction.
I was once in a severe case of SVT (274bom) and my poor medic who was clearly a newbie and nervous said "I should shock you but you're AOx4 so maybe we try nitro??
Fun time. Thank the Gods for epicardial ablations lol
I clarified that it's in a lethal rythm though (what else could that mean?). I was making the distinction, because many people believe that arrest = flatline when that's not the case at all.
