My analogy is sensible and your attempt to extend it, is nonsensical. I don't think you're interested in good faith discussion, but I'll try to make the world a slightly better place with some facts.
There are multiple classes of Antiarrhythmic agents that address different chemical channels, to the same effect. Heart trauma, from surgery scarring to infarctions, and variable base chemistry, requires an array of different channels to reduce heart rate consistently. Multiple channel treatments are often used in tandem or rotated. These are called beta blockers for simplicity. ie These drugs stop the signals from the spine from getting to the heart the same way they normally would.

Beta blockers are not magic, nor were they invented in the 50s or the 90s. The invention of a treatment does not correlate with the performance of a formal study accepted by modern medicine in some locale. Studies are necessarily narrow and it can take decades for a particular treatment vector to be confirmed or decried, despite the treatment being widely used prior in a more general application. Heart arrhythmias, have a very similar treatment across the world, across time.

As a heart patient of 50 years (first surgery at age 2), having spent a non-trivial amount of my life in hospital and bedridden at times, I am painfully aware that beta blockers are not one of them. Going from 200 bpm to 80 with an IV/pill is demonstrable and prevents the heart from tearing itself apart. Beta blockers save lives, period. Statistically, you will be treated with beta blockers as well, regardless of your feelings.
If you want to argue about blood thinners, the advances in that chemical realm are varied and a mixed bag. If you want to argue about valve technology, the blood flow dynamics and testing is generations beyond even my second valve replacement over 20 years ago due to automation, material technology, sample data, and evolved standards.
I hope this helps you in your next discussion about the topic.
